Limitations of Use:

Not recommended for the treatment of diabetic ketoacidosis (1)

Not recommended in patients who smoke or who have recently stopped smoking (1)

2 Dosage And Administration

Only administer via oral inhalation using the AFREZZA inhaler (2.2)

Administer at the beginning of each meal (2.2)

See full prescribing information for the recommended starting mealtime dosage in insulin-naïve patients and patients who are using subcutaneous mealtime insulin or pre-mixed insulin (2.3)

Modify dosage based on the patient's metabolic needs, blood glucose monitoring results, and glycemic control goal (2.3)

If blood glucose control is not achieved in patients requiring high AFREZZA doses, consider discontinuing AFREZZA (2.4)

2.1 Lung Function Assessment Prior to Administration

AFREZZA is contraindicated in patients with chronic lung disease because of the risk of acute bronchospasm in these patients. Before initiating AFREZZA, perform a medical history, physical examination and spirometry (FEV₁) in all patients to identify potential lung disease [see Contraindications (4) and Warnings and Precautions (5.1)].

2.2 Important Administration and Discard Instructions

Only administer AFREZZA via oral inhalation using the AFREZZA Inhaler. Administer AFREZZA at the beginning of each meal. Administer AFREZZA using a single inhalation per cartridge (if the dose is greater than the contents of a single cartridge, more than one cartridge is needed) [see Dosage and Administration (2.3)]. For additional administration instructions on how to use the AFREZZA Inhaler [see Dosage and Administration (2.6)] and see the Instructions for Use.

The AFREZZA Inhaler can be used for up to 15 days from the date of first use. After 15 days of use, the inhaler must be discarded and replaced with a new inhaler.

2.3 Recommended Starting Mealtime Dosage

For insulin naïve patients, start on 4 units of AFREZZA at the beginning of each meal.

For patients using subcutaneous, mealtime (prandial) insulin:

Determine the appropriate AFREZZA dose for each meal by converting from the injected insulin dose using Figure 1.

When switching from another insulin to AFREZZA, a different insulin dose may be needed requiring increased frequency of blood glucose monitoring [see Warnings and Precautions (5.2)].

For patients using subcutaneous, pre-mixed insulin:

Estimate the mealtime injected dose by dividing half of the total daily injected pre-mixed insulin dose equally among the three meals of the day. When switching from another insulin to AFREZZA, a different insulin dose may be needed. When switching a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2)].

Convert each estimated injected mealtime dose to an appropriate AFREZZA dose using Figure 1.

Administer half of the total daily injected pre-mixed dose as an injected basal insulin dose.

For AFREZZA doses exceeding the contents of a single cartridge at mealtime, inhalations from more than one cartridge are necessary. To achieve the required total mealtime dose, use a combination of 4 unit, 8 unit, and 12 unit cartridges. Examples of cartridge combinations for doses of up to 24 units are shown in Figure 1. For doses above 24 units, use combinations of different multiple cartridges.
Figure 1. Mealtime AFREZZA Starting Dose Conversion Table

2.4 Mealtime Dosage Modification

Modify the AFREZZA dosage based on the patient's metabolic needs, blood glucose monitoring results, and glycemic control goal.

Dosage modifications may be needed with changes in physical activity, changes in meal patterns (i.e., macronutrient content or timing of food intake), changes in renal or hepatic function or during acute illness [see Warnings and Precautions (5.3) and Use in Specific Populations (8.6, 8.7)].

Carefully monitor blood glucose control in patients requiring high AFREZZA doses. If blood glucose control is not achieved with increased AFREZZA doses in these patients, consider discontinuing AFREZZA.

2.5 Dosage Modifications for Drug Interactions

Dosage modification may be needed when:

AFREZZA is used concomitantly with certain drugs that increase and/or decrease the glucose lowering effect [see Drug Interactions (7.1, 7.2, 7.3)].

Switching from another insulin to AFREZZA [see Dosage and Administration (2.2) and Warnings and Precautions (5.2)]

2.6 Administration Instructions

Refer patients to the Instructions for Use for detailed instructions and visuals on how to prepare, administer, and store AFREZZA; use the AFREZZA cartridges; and use the AFREZZA inhaler. Critical administration instructions are as follows:

Keep the inhaler level with the white mouthpiece on top and purple base on the bottom after a cartridge has been inserted into the inhaler. Loss of drug effect can occur if the inhaler is turned upside down, held with the mouthpiece pointing down, shaken, or dropped after the cartridge has been inserted but before the dose has been administered. If any of the above occur, replace the cartridge before use.

Hold the inhaler away from the mouth and fully exhale.

After the inhaler is placed in the mouth and the lips form a seal, tilt the inhaler down towards the chin while keeping the head level.

With the mouth closed around the mouthpiece, inhale deeply through the inhaler.

Hold the breath for as long as comfortable and at the same time remove the inhaler from the mouth.

After holding the breath, exhale and continue to breathe normally.

Hypersensitivity to regular human insulin or any of the excipients in AFREZZA [see Warnings and Precautions (5.7)]

During episodes of hypoglycemia (4)

Chronic lung disease, such as asthma, or chronic obstructive pulmonary disease (4)

Hypersensitivity to regular human insulin or any of the excipients in AFREZZA (4)

5 Warnings And Precautions

Hypoglycemia or Hyperglycemia with Changes in Insulin Regimen: Carry out under close medical supervision and increase frequency of blood glucose monitoring. For patients with type 2 diabetes mellitus, oral antidiabetic treatment dosage modifications may be needed. (5.2)

Hypoglycemia (may be life-threatening): Increase frequency of glucose monitoring in patients at higher risk for hypoglycemia and those who have reduced symptomatic awareness of hypoglycemia. (5.3)

Decline in Pulmonary Function: Assess pulmonary function (e.g., spirometry (FEV₁)) before initiating, after 6 months of therapy, and annually, even in the absence of pulmonary symptoms. In patients who have a decline of ≥ 20% in FEV₁ from baseline, consider discontinuing AFREZZA. (2.5, 5.4)

Lung Cancer: In patients with active lung cancer, a prior history of lung cancer, or in patients at risk for lung cancer, consider whether the benefits of AFREZZA use outweigh this potential risk. (5.5)

Diabetic Ketoacidosis: In patients at risk for DKA, increase the frequency of glucose monitoring and consider changing to alternate route of insulin delivery. (5.6)

Hypersensitivity Reactions: Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including AFREZZA. If hypersensitivity reactions occur, discontinue AFREZZA, treat per standard of care and monitor until symptoms and signs resolve. (5.7)

Hypokalemia (may be life-threatening): Monitor potassium levels in patients at risk of hypokalemia. (5.8)

Fluid Retention and Heart Failure with Concomitant Use of Thiazolidinediones (TZDs): Observe for signs and symptoms of heart failure; consider dosage reduction or discontinuation if heart failure occurs. (5.9)

5.1 Acute Bronchospasm in Patients with Chronic Lung Disease

Because of the risk of acute bronchospasm, AFREZZA is contraindicated in patients with chronic lung disease such as asthma or COPD [see Contraindications (4)]. Before initiating therapy with AFREZZA, evaluate all patients with a medical history, physical examination, and spirometry (FEV₁) to identify potential underlying lung disease.

Acute bronchospasm has been observed in AFREZZA-treated patients with asthma and COPD. In a study of patients with asthma whose bronchodilators were temporarily withheld for assessment, bronchoconstriction and wheezing following AFREZZA dosing was reported in 29% (5 out of 17) and 0% (0 out of 13) of patients with and without a diagnosis of asthma, respectively. In this study, a mean decline in FEV₁ of 400 mL was observed 15 minutes after a single AFREZZA dose in patients with asthma. In a subset study of patients with COPD (n=8), a mean decline in FEV₁ of 200 mL was observed 18 minutes after a single AFREZZA dose.

5.2 Hypoglycemia or Hyperglycemia with Changes in Insulin Regimen

Glucose monitoring is essential for patients receiving insulin therapy. Changes in insulin strength, manufacturer, type, or method of administration may affect glycemic control and predispose to hypoglycemia [see Warnings and Precautions (5.3)] or hyperglycemia. These changes should be made under close medical supervision and the frequency of blood glucose monitoring should be increased. For patients with type 2 diabetes, dosage modifications of concomitant oral antidiabetic treatment may be needed [see Drug Interactions (7.1, 7.2, and 7.3)].

5.3 Hypoglycemia

Glucose monitoring is essential for patients receiving insulin therapy. Hypoglycemia is the most common adverse reaction associated with insulins, including AFREZZA. Severe hypoglycemia can cause seizures, may be life-threatening, or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place an individual and others at risk in situations where these abilities are important (e.g., driving or operating other machinery).

The timing of hypoglycemia usually reflects the time-action profile of the administered insulin formulation. AFREZZA has a distinct time action profile [see Clinical Pharmacology (12)], which impacts the timing of hypoglycemia. Hypoglycemia can happen suddenly, and symptoms may differ across patients and change over time in the same patient. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic nerve disease, in patients using certain medications [see Drug Interactions (7.4)], or in patients who experience recurrent hypoglycemia.

Factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content or timing of meals), changes in level of physical activity, or changes to co-administered medication [see Drug Interactions (7)]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations (8.6, 8.7)].

Risk Mitigation Strategies for Hypoglycemia

Patients and caregivers should be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended.

5.4 Decline in Pulmonary Function

AFREZZA causes a decline in pulmonary function over time as measured by FEV₁. In clinical trials excluding patients with chronic lung disease and lasting up to 2 years, AFREZZA-treated patients experienced a small [40 mL (95% CI: -80, -1)] but greater FEV₁ decline than comparator-treated patients. The FEV₁ decline was noted within the first 3 months, and persisted for the entire duration of therapy (up to 2 years of observation). In this population, the annual rate of FEV₁ decline did not appear to worsen with increased duration of use. The effects of AFREZZA on pulmonary function for treatment duration longer than 2 years has not been established. There are insufficient data in long term studies to draw conclusions regarding reversal of the effect on FEV₁ after discontinuation of AFREZZA. The observed changes in FEV₁ were similar in patients with type 1 and type 2 diabetes.

Assess pulmonary function (e.g., spirometry) at baseline, after the first 6 months of therapy, and annually thereafter, even in the absence of pulmonary symptoms. In patients who have a decline of ≥ 20% in FEV₁ from baseline, consider discontinuing AFREZZA. Consider more frequent monitoring of pulmonary function in patients with pulmonary symptoms such as wheezing, bronchospasm, breathing difficulties, or persistent or recurring cough. If symptoms persist, discontinue AFREZZA [see Adverse Reactions (6)].

5.5 Lung Cancer

In clinical trials, two cases of lung cancer, one in controlled trials and one in uncontrolled trials (2 cases in 2,750 patient-years of exposure), were observed in patients exposed to AFREZZA while no cases of lung cancer were observed in patients exposed to comparators (0 cases in 2,169 patient-years of exposure). In both cases, a prior history of heavy tobacco use was identified as a risk factor for lung cancer. Two additional cases of lung cancer (squamous cell and lung blastoma) occurred in non-smokers exposed to AFREZZA and were reported by investigators after clinical trial completion. These data are insufficient to determine whether AFREZZA has an effect on lung or respiratory tract tumors.

In patients with active lung cancer, a prior history of lung cancer, or in patients at risk for lung cancer, consider whether the benefits of AFREZZA use outweigh this potential risk.

5.6 Diabetic Ketoacidosis

In clinical trials enrolling patients with type 1 diabetes, diabetic ketoacidosis (DKA) was more common in AFREZZA-treated patients (0.43%; n=13) than in comparator-treated patients (0.14%; n=3). Patients with type 1 diabetes should always use AFREZZA in combination with basal insulin. In patients at risk for DKA, such as those with an acute illness or infection, increase the frequency of glucose monitoring and consider discontinuing AFREZZA and giving insulin using an alternate route of administration.

5.7 Hypersensitivity Reactions

Severe, life-threatening, generalized allergy, including anaphylaxis, can occur with insulin products, including AFREZZA.

If hypersensitivity reactions occur, discontinue AFREZZA, treat per standard of care and monitor until symptoms and signs resolve [see Adverse Reactions (6)]. AFREZZA is contraindicated in patients who have had hypersensitivity reactions to AFREZZA or any of its excipients [see Contraindications (4)].

5.8 Hypokalemia

All insulin products, including AFREZZA, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death.

Monitor potassium levels in AFREZZA-treated patients at risk for hypokalemia (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations and patients receiving intravenously administered insulin).

5.9 Fluid Retention and Heart Failure with Concomitant Use of PPAR-gamma Agonists

Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure.

Patients treated with insulin, including AFREZZA, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist should be considered.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described below reflect exposure of 3,017 patients to AFREZZA and include 1,026 patients with type 1 diabetes and 1,991 patients with type 2 diabetes. The mean exposure duration was 8.2 months for patients with type 1 diabetes and those with type 2 diabetes. In the overall population:

1,874 patients were exposed to AFREZZA for 6 months and 724 patients for greater than one year.

620 and 1,254 patients with type 1 and type 2 diabetes, respectively, were exposed to AFREZZA for up to 6 months.

238 and 486 patients with type 1 and type 2 diabetes, respectively, were exposed to AFREZZA for greater than one year (median exposure = 1.8 years).

AFREZZA was studied in placebo and active-controlled trials (n = 3 and n = 10, respectively).

The mean age of the population was 50.2 years and 20 patients were older than 75 years of age; 51% of the population were males; 83% were White, 5% were Black or African American, and 2% were Asian; 10% were Hispanic. At baseline, the type 1 diabetes population had diabetes for an average of 16.6 years and had a mean HbA1c of 8.3%, and the type 2 diabetes population had diabetes for an average of 10.7 years and had a mean HbA1c of 8.8%. At baseline, 33% of the population reported peripheral neuropathy, 32% reported retinopathy and 20% had a history of cardiovascular disease.

Table 1 shows the frequency of common adverse reactions, excluding hypoglycemia, associated with the use of AFREZZA in the pool of controlled trials in type 2 diabetes patients. These adverse reactions were not present at baseline, occurred more commonly on AFREZZA than on placebo and/or comparator and occurred in at least 2% of patients treated with AFREZZA.

Hypoglycemia

Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including AFREZZA [see Warnings and Precautions (5.3)]. The incidence of severe and non-severe hypoglycemia in AFREZZA-treated patients versus placebo-treated patients with type 2 diabetes is shown in Table 3. A hypoglycemic episode was recorded if a patient reported symptoms of hypoglycemia with or without a blood glucose value consistent with hypoglycemia. Severe hypoglycemia was defined as an event with symptoms consistent with hypoglycemia requiring the assistance of another person and associated with either a blood glucose value consistent with hypoglycemia or prompt recovery after treatment for hypoglycemia.

Table 3. Incidence of Severe and Non-Severe Hypoglycemia in a Placebo-Controlled Study of Patients with Type 2 Diabetes

AFREZZA (N=177) Placebo (N=176)

Severe Hypoglycemia 5.1% 1.7%

Non-Severe Hypoglycemia 67% 30%

Cough

Approximately 27% of patients treated with AFREZZA reported cough, compared to approximately 5% of patients treated with comparator. In clinical trials, cough was the most common reason for discontinuation of AFREZZA therapy (3% of AFREZZA-treated patients).

Pulmonary Function Decline

In clinical trials lasting up to 2 years, excluding patients with chronic lung disease, patients treated with AFREZZA had a 40 mL (95% CI: -80, -1) greater decline from baseline in forced expiratory volume in one second (FEV₁) compared to patients treated with comparator anti-diabetes treatments. The decline occurred during the first 3 months of therapy and persisted over 2 years (Figure 2). A decline in FEV₁ of ≥ 15% occurred in 6% of AFREZZA-treated patients compared to 3% of comparator-treated patients [see Warnings and Precautions (5.4)].
Figure 2. Mean (+/-SE) Change in FEV ₁ (Liters) from Baseline for Type 1 and Type 2 Diabetes Patients

Weight Gain

Weight gain has occurred with some insulin therapies, including AFREZZA. Weight gain has been attributed to the anabolic effects of insulin and the decrease in glycosuria. In a clinical trial of patients with type 2 diabetes [see Clinical Studies (14.3)], there was a mean 0.49 kg weight gain among AFREZZA-treated patients compared with a mean 1.13 kg weight loss among placebo-treated patients.

6.2 Postmarketing Experience

The following adverse reaction has been identified during post approval use of AFREZZA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: bronchospasm.

7 Drug Interactions

Drugs that may increase the risk of hypoglycemia (7.1, 7.3)

Drugs that may decrease blood glucose lowering effect of AFREZZA (7.2, 7.3)

Drugs that may affect hypoglycemic signs and symptoms (7.4)

7.1 Drugs That May Increase the Risk of Hypoglycemia

The risk of hypoglycemia associated with AFREZZA use may be increased with antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, salicylates, somatostatin analogs (e.g., octreotide), and sulfonamide antibiotics. Dose modification and increased frequency of glucose monitoring may be required when AFREZZA is given concomitantly with these drugs.

7.2 Drugs That May Decrease the Blood Glucose Lowering Effect of AFREZZA

The glucose lowering effect of AFREZZA may be decreased when given concomitantly with atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline) and thyroid hormones. Dose adjustment and increased frequency of glucose monitoring may be required when AFREZZA is given concomitantly with these drugs.

7.3 Drugs That May Increase or Decrease the Blood Glucose Lowering Effect of AFREZZA

The glucose lowering effect of AFREZZA may be increased or decreased when co-administered with alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Dose modification and increased frequency of glucose monitoring may be required when AFREZZA is given concomitantly with these drugs.

7.4 Drugs That May Affect Hypoglycemia Signs and Symptoms

The signs and symptoms of hypoglycemia may be blunted when beta-blockers, clonidine, guanethidine, and reserpine are given concomitantly with AFREZZA.

8 Use In Specific Populations

8.1 Pregnancy

Risk Summary

Limited available data with AFREZZA use in pregnant women are insufficient to determine drug-associated risks for adverse developmental outcomes. Available information from published studies with human insulin use during pregnancy has not reported a clear association with human insulin and adverse developmental outcomes (see Data ). There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations ). In animal reproduction studies, there were no adverse developmental outcomes with subcutaneous administration of carrier particles (vehicle without insulin) to pregnant rats during organogenesis at doses 21 times the human daily dose of 99 mg AFREZZA, based on AUC (see Data).

The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with HbA1c >7 and has been reported to be as high as 20-25% in women with HbA1c >10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Clinical Considerations

Disease-associated maternal and/or embryo/fetal risk

Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, stillbirth, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, still birth, and macrosomia- related morbidity.

Data

Human Data

There are limited data with AFREZZA use in pregnant women. Published data do not report a clear association with human insulin and major birth defects, miscarriage, or adverse maternal or fetal outcomes when human insulin is used during pregnancy. However, these studies cannot definitely establish the absence of any risk because of methodological limitations including small sample size and lack of blinding.

Animal Data

In pregnant rats given subcutaneous doses of 10, 30, and 100 mg/kg/day of carrier particles (vehicle without insulin) from gestation day 6 through 17 (organogenesis), no major malformations were observed at doses up to 100 mg/kg/day (21 times the human systemic exposure at a daily dose of 99 mg AFREZZA, based on AUC).

In pregnant rabbits given subcutaneous doses of 2, 10, and 100 mg/kg/day of carrier particles (vehicle without insulin) from gestation day 7 through 19 (organogenesis), adverse maternal effects were observed in all dose groups (at human systemic exposure following a daily dose of 99 mg AFREZZA, based on AUC).

In pregnant rats given subcutaneous doses of 10, 30, and 100 mg/kg/day of carrier particles (vehicle without insulin) from gestation day 7 through lactation day 20 (weaning), decreased epididymis and testes weights were observed in F1 male offspring, however, no decrease in fertility was noted, and impaired learning were observed in F1 pups at ³ 30 mg/kg/day (6 times the human systemic exposure at a daily dose of 99 mg AFREZZA, based on AUC).

8.2 Lactation

Risk Summary

There are no data on the presence of AFREZZA in human milk, the effects on the breastfed infant, or the effects on milk production. One small published study reported that exogenous subcutaneous insulin was present in human milk. No adverse effects in infants were noted. The carrier particles are present in rat milk (see Data ). Potential adverse reactions that are related to inhalational administration of AFREZZA are unlikely to be associated with potential exposure of AFREZZA through breast milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for AFREZZA and any potential adverse effects on the breastfed infant from AFREZZA or from the underlying maternal condition.

Data

Subcutaneous administration of the carrier particle in lactating rats resulted in excretion of the carrier particle in rat milk at levels that were approximately 10% of the maternal exposure. Given the results of the rat study, it is highly likely that the insulin and carrier in AFREZZA are excreted in human milk.

8.4 Pediatric Use

The safety and effectiveness of AFREZZA to improve glycemic control in pediatric patients with diabetes mellitus has not been established. AFREZZA has not been studied in pediatric patients.

8.5 Geriatric Use

In the AFREZZA clinical studies, 671 (12%) patients were 65 years of age or older, of which 42 (0.8%) were 75 years of age or older. In these studies, 381 (13%) of AFREZZA-treated patients were 65 years of age or older, of which 20 (0.7%) were 75 years of age or older. No overall differences in effectiveness of AFREZZA have been observed between patients 65 years of age and older and younger adult patients [see Clinical Studies (14)]. Clinical studies of AFREZZA did not include sufficient numbers of patients 65 years of age and older to determine whether there were differences in safety between these patients and younger adult patients.

Pharmacokinetic and pharmacodynamic studies to assess the effect of age on pharmacokinetics or pharmacodynamics on insulin human, respectively, have not been conducted.

8.6 Hepatic Impairment

The effect of hepatic impairment on the pharmacokinetics of AFREZZA has not been studied. Frequent glucose monitoring and a lower dosage may be necessary in AFREZZA-treated patients with hepatic impairment [see Warnings and Precautions (5.3)].

8.7 Renal Impairment

The effect of renal impairment on the pharmacokinetics of AFREZZA has not been studied. Some studies with human insulin have shown increased circulating levels of insulin in patients with renal failure. Frequent glucose monitoring and a lower dosage may be necessary in AFREZZA-treated patients with renal impairment [see Warnings and Precautions (5.3)].

10 Overdosage

Excess insulin administration may cause hypoglycemia and hypokalemia [see Warnings and Precautions (5.3, 5.8)].

Mild episodes of hypoglycemia due to insulin overdose can usually be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise, may be needed.

Severe episodes of hypoglycemia (due to insulin overdose) with coma, seizure, or neurologic impairment may be treated with intramuscular or subcutaneous glucagon or concentrated intravenous glucose. After apparent clinical recovery from hypoglycemia, continued observation and additional carbohydrate intake may be necessary to avoid recurrence of hypoglycemia. Hypokalemia should be corrected appropriately.

11.1 AFREZZA Cartridges

Human insulin is a rapid acting human insulin produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12). Chemically, human insulin has the empirical formula C₂₅₇H₃₈₃N₆₅O₇₇S₆ and a molecular weight of 5808. Human insulin has the following primary amino acid sequence:

AFREZZA (human insulin) inhalation powder is available in single-use plastic cartridges filled with a white powder containing insulin (human), which is administered via oral inhalation using the AFREZZA Inhaler only.

Insulin is adsorbed onto carrier particles consisting of fumaryl diketopiperazine (FDKP) and polysorbate 80.

AFREZZA Inhalation Powder is a dry powder supplied as 4 unit, 8 unit or 12 unit cartridges.

11.2 AFREZZA Inhaler

The AFREZZA Inhaler is breath-powered by the patient. When the patient inhales through the device, the powder is aerosolized and delivered to the lung. The amount of AFREZZA delivered to the lung will depend on individual patient factors.

12 Clinical Pharmacology

12.1 Mechanism of Action

Insulin lowers blood glucose levels in adult patients with diabetes mellitus by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in adipocytes, inhibits proteolysis, and enhances protein synthesis.

12.2 Pharmacodynamics

The time course of insulin action (i.e., glucose lowering) may vary considerably in different patients or within the same patient. The average pharmacodynamic profile [i.e., glucose lowering effect measured by glucose infusion rate (GIR) over time in a euglycemic clamp study] after administration of a single AFREZZA dose of 4, 12, and 48 units in 30 patients with type 1 diabetes is shown in Figure 3(A), and key characteristics regarding the timing of the effects are described in Table 4:

Table 4. Timing of Insulin Effect (i.e., mean pharmacodynamics effect) After Administration of a Single AFREZZA Dose in Patients (N=30) with Type 1 Diabetes Mellitus

Parameter for Insulin Effect AFREZZA 4 units AFREZZA 12 units AFREZZA 48 units

Time to first measurable effect ~12 minutes ~12 minutes ~12 minutes

Time to peak effect ~35 minutes ~45 minutes ~55 minutes

Time for effect to return to baseline ~90 minutes ~180 minutes ~270 minutes

Figure 3. Results After Administration of AFREZZA 4, 12, and 48 Units in Patients with T1DM (N=30) A) Mean Insulin Effect (Baseline-Corrected Glucose Infusion Rate); and B) Pharmacokinetic (Baseline-Corrected Serum Insulin Concentration Profiles)

On average, the pharmacodynamics effect of AFREZZA, measured as area under the glucose infusion rate – time curve (AUC GIR) increased linearly with doses up to 48 units (106, 387, and 1581 mg/kg for 4, 12, and 48 units doses, respectively).

Intrapatient variability in AUC GIR and GIR_max was approximately 28% (95% CI 21-42%) and 27% (95% CI 20-40%), respectively.

12.3 Pharmacokinetics

The area under the plasma concentration versus time curve (AUC) of insulin increased dose proportionally up to 48 units. Intrapatient variability of AUC and peak concentration (C_max) of insulin was approximately 16% (95% CI 12-23%) and 21% (95% CI 16-30%), respectively.

Absorption

The pharmacokinetic profiles for orally inhaled AFREZZA 4, 12, and 48 units from a study in 30 patients with type 1 diabetes are shown in Figure 5(B). The time to maximum serum insulin concentration (t_max) ranged from 10-20 minutes after oral inhalation of 4 to 48 units of AFREZZA.

Elimination

The apparent terminal half-life ranged from 120 to 206 minutes. Serum insulin concentrations declined to baseline by approximately 60 to 240 minutes.

Metabolism and Excretion

The metabolism and excretion of AFREZZA are comparable to regular human insulin.

Carrier Particles

Clinical pharmacology studies showed that carrier particles [see Description (11.1)] are not metabolized and are eliminated unchanged in the urine following the lung absorption. Following oral inhalation of AFREZZA, a mean of 39% of the inhaled dose of carrier particles was distributed to the lungs and a mean of 7% of the dose was swallowed. The swallowed fraction was not absorbed from the GI tract and was eliminated unchanged in the feces.

Drug Interaction Studies

Bronchodilators and Inhaled Steroids

Albuterol increased the AUC insulin after AFREZZA administration by 25% in patients with asthma [see Drug Interactions (7.2)]. AFREZZA is contraindicated in patients with asthma.

In a study in healthy volunteers no significant change in insulin exposure was observed when fluticasone was administered following AFREZZA administration.

12.6 Immunogenicity

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of insulin human or of other insulin human products.

Increases in anti-insulin antibody concentrations were observed in patients treated with AFREZZA. Increases in anti-insulin antibodies were observed more frequently in patients treated with AFREZZA than in patients treated with subcutaneously injected mealtime insulin. There was no clinically significant effect of anti-drug antibodies on safety or effectiveness (as measured by HbA1c and fasting plasma glucose) of AFREZZA over the treatment duration of the studies which spanned 3 to 24 months.

13 Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

In a 104 week carcinogenicity study, rats were given doses up to 46 mg/kg/day of the carrier and up to 1.23 mg/kg/day of insulin, by nose-only inhalation. No increased incidence of tumors was observed at systemic exposures equivalent to the insulin at a daily AFREZZA dose of 99 mg, based on a comparison of relative body surface areas across species.

No increased incidence of tumors was observed in a 26 week carcinogenicity study in transgenic mice (Tg-ras-H2) given doses up to 75 mg/kg/day of carrier and up to 5 mg/kg/day of AFREZZA.

AFREZZA was not genotoxic in Ames bacterial mutagenicity assay and in the chromosome aberration assay, using human peripheral lymphocytes with or without metabolic activation. The carrier alone was not genotoxic in the in vivo mouse micronucleus assay.

In fertility study in male and female rats at subcutaneous doses of 10, 30, and 100 mg/kg/day of carrier (vehicle without insulin), there were no adverse effects on male fertility at doses up to 100 mg/kg/day. In female rats dosed 2 weeks prior to mating until gestation day 7, there was increased pre- and post-implantation loss at 100 mg/kg/day but not at 30 mg/kg/day (21 times and 6 times, respectively the human systemic exposure at a daily dose of 99 mg AFREZZA, based on AUC).

14 Clinical Studies

14.1 Overview of Clinical Studies of AFREZZA in Adults for Diabetes Mellitus

AFREZZA has been studied in adults with type 1 diabetes in combination with basal insulin. The efficacy of AFREZZA, in combination with basal insulin, in type 1 diabetes patients was compared to insulin aspart in combination with basal insulin.

AFREZZA has been studied in adults with type 2 diabetes in combination with oral antidiabetic drugs. The efficacy of AFREZZA in type 2 diabetes patients was compared to placebo inhalation.

14.2 Adults with Type 1 Diabetes

Patients with inadequately controlled type 1 diabetes participated in a 24-week, open-label, active-controlled study to evaluate the glucose lowering effect of mealtime AFREZZA used in combination with a basal insulin. Following a 4-week basal insulin optimization period, 344 patients were randomized to AFREZZA by oral inhalation (n=174) or insulin aspart given subcutaneously (n=170) at each meal of the day. All patients received basal insulin. Mealtime insulin doses were titrated to glycemic goals for the first 12 weeks and kept stable for the last 12 weeks of the study.

Results

At Week 24, treatment with mealtime AFREZZA and basal insulin provided a mean reduction in HbA1c that met the pre-specified non-inferiority margin of 0.4%. AFREZZA and basal insulin provided less HbA1c reduction than insulin aspart and basal insulin, and the difference was statistically significant. More patients in the insulin aspart and basal insulin group achieved the HbA1c target of ≤7% (Table 5).

14.3 Adults with Type 2 Diabetes

A total of 479 adult patients with type 2 diabetes inadequately controlled on optimal/maximally tolerated doses of metformin only, or 2 or more oral antidiabetic (OAD) agents participated in a 24-week, double-blind, placebo-controlled study. Following a 6-week run-in period, 353 patients were randomized to AFREZZA by oral inhalation (n=177) or an inhaled placebo powder without insulin (n=176). Insulin doses were titrated for the first 12 weeks and kept stable for the last 12 weeks of the study. OADs doses were kept stable in the study.

Results

At Week 24, treatment with AFREZZA plus OADs provided a mean reduction in HbA1c that was statistically significantly greater compared to the HbA1c reduction observed in the placebo plus OADs group (Table 6).

Revised 02/2023

MEDICATION GUIDE AFREZZA® (uh-FREZZ-uh) (insulin human) inhalation powder, for oral inhalation use

What is the most important information I should know about AFREZZA? AFREZZA can cause serious side effects, including:

Sudden lung problems (bronchospasms). Do not use AFREZZA if you have long-term (chronic) lung problems such as asthma or chronic obstructive pulmonary disease (COPD). Before starting AFREZZA, your healthcare provider will give you a breathing test to check how your lungs are working.

What is AFREZZA?

AFREZZA is a man-made insulin that is breathed-in through your lungs (inhaled) and is used to control high blood sugar in adults with diabetes mellitus.

AFREZZA is not for use to treat diabetic ketoacidosis. AFREZZA must be used with basal insulin in people who have type 1 diabetes mellitus.

It is not known if AFREZZA is safe and effective for use in people who smoke. AFREZZA is not for use in people who smoke or have recently stopped smoking (less than 6 months).

It is not known if AFREZZA is safe and effective in children under 18 years of age.

Who should not use AFREZZA? Do not use AFREZZA if you:

Have chronic lung problems such as asthma or COPD.

Are allergic to regular human insulin or any of the ingredients in AFREZZA. See the end of this Medication Guide for a complete ul of ingredients in AFREZZA.

Are having an episode of low blood sugar (hypoglycemia).

What should I tell my healthcare provider before using AFREZZA? Before using AFREZZA, tell your healthcare provider about all your medical conditions, including if you:

Have lung problems such as asthma or COPD

Have or have had lung cancer

Are using any inhaled medications

Smoke or have recently stopped smoking

Have kidney or liver problems

Are pregnant, planning to become pregnant, or are breastfeeding. AFREZZA may harm your unborn or breastfeeding baby.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins or herbal supplements. Before you start using AFREZZA, talk to your healthcare provider about low blood sugar and how to manage it.

How should I use AFREZZA?

Read the detailed Instructions for Use that comes with your AFREZZA.

Take AFREZZA exactly as your healthcare provider tells you to. Your healthcare provider should tell you how much AFREZZA to use and when to use it.

Know the strength of AFREZZA you use. Do not change the amount of AFREZZA you use unless your healthcare provider tells you to.

Take AFREZZA at the beginning of your meal.

Check your blood sugar levels. Ask your healthcare provider what your blood sugar should be and when you should check your blood sugar levels.

Keep AFREZZA and all medicines out of the reach of children.

Your dose of AFREZZA may need to change because of:

Change in level of physical activity or exercise, weight gain or loss, increased stress, illness, change in diet, or because of other medicines you take.

What should I avoid while using AFREZZA? While using AFREZZA do not:

Drive or operate heavy machinery, until you know how AFREZZA affects you

Drink alcohol or use over-the-counter medicines that contain alcohol

Smoke

What are the possible side effects of AFREZZA?

AFREZZA may cause serious side effects that can lead to death, including:

See “What is the most important information I should know about AFREZZA?”

Low blood sugar (hypoglycemia). Signs and symptoms that may indicate low blood sugar include:

Dizziness or light-headedness, sweating, confusion, headache, blurred vision, slurred speech, shakiness, fast heartbeat, anxiety, irritability or mood change, hunger.

Decreased lung function. Your healthcare provider should check how your lungs are working before you start using AFREZZA, 6 months after you start using it and yearly after that.

Lung cancer. In studies of AFREZZA in people with diabetes, lung cancer occurred in a few more people who were taking AFREZZA than in people who were taking other diabetes medications. There were too few cases to know if lung cancer was related to AFREZZA. If you have lung cancer, you and your healthcare provider should decide if you should use AFREZZA.

Diabetic ketoacidosis. Talk to your healthcare provider if you have an illness. Your AFREZZA dose or how often you check your blood sugar may need to be changed.

Severe allergic reaction (whole body reaction). Get medical help right away if you have any of these signs or symptoms of a severe allergic reaction:

A rash over your whole body, trouble breathing, a fast heartbeat, or sweating.

Low potassium in your blood (hypokalemia).

Heart failure. Taking certain diabetes pills called thiazolidinediones or “TZDs” with AFREZZA may cause heart failure in some people. This can happen even if you have never had heart failure or heart problems before. If you already have heart failure it may get worse while you take TZDs with AFREZZA. Your healthcare provider should monitor you closely while you are taking TZDs with AFREZZA. Tell your healthcare provider if you have any new or worse symptoms of heart failure including:

Shortness of breath, swelling of your ankles or feet, sudden weight gain.

Treatment with TZDs and AFREZZA may need to be changed or stopped by your healthcare provider if you have new or worse heart failure.

Get emergency medical help if you have:

Trouble breathing, shortness of breath, fast heartbeat, swelling of your face, tongue, or throat, sweating, extreme drowsiness, dizziness, confusion.

The most common side effects of AFREZZA include:

Low blood sugar (hypoglycemia), cough, sore throat.

These are not all the possible side effects of AFREZZA. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 (1-800-332-1088).

General information about the safe and effective use of AFREZZA. Medicines are sometimes prescribed for purposes other than those uled in a Medication Guide. Do not use AFREZZA for a condition for which it was not prescribed. Do not give AFREZZA to other people, even if they have the same symptoms that you have. It may harm them.This Medication Guide summarizes the most important information about AFREZZA. If you would like more information, talk with your healthcare provider. You can ask your pharmacist or healthcare provider for information about AFREZZA that is written for health professionals.

Instructions For Use Section

INSTRUCTIONS FOR USEAFREZZA® (uh-FREZZ-uh)(insulin human) inhalation powder, for oral inhalation use

This “Instructions for Use” contains information on how to use AFREZZA^® (insulin human) Inhalation Powder.

Read this Instructions for Use before you start using AFREZZA and each time you get a new AFREZZA Inhaler. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

Your healthcare provider should show you how to use your AFREZZA Inhaler the right way before you use it for the first time.

Important information about AFREZZA:

AFREZZA comes in 3 strengths (see Figure A):

4 units (blue cartridge)

8 units (green cartridge)

12 units (yellow cartridge)

Figure A

If your prescribed AFREZZA dose is higher than 12 units, you will need to use more than 1 cartridge.

If you need to use more than 1 cartridge for your dose, throw away the used cartridge before getting a new one. You can tell when a cartridge has been used, because the cup has moved to the center.

Do not try to open the AFREZZA cartridges. The AFREZZA Inhaler opens the cartridge automatically during use.

AFREZZA cartridges should only be used with the AFREZZA Inhaler. Do not try to breathe in the AFREZZA insulin powder in any other way. Do not put cartridges in your mouth and do not swallow cartridges.

Use only 1 AFREZZA Inhaler at a time. The same inhaler should be used for the 4 unit, 8 unit or 12 unit cartridges.

Store the inhaler in a clean, dry place with the mouthpiece cover on until your next dose.

Throw away your AFREZZA Inhaler after 15 days and get a new one.

If you are having problems with your AFREZZA Inhaler or if it breaks and you need a new one, call 1-877-323-8505.

Know your AFREZZA Inhaler:

Know your AFREZZA cartridges:

How to take your dose of AFREZZA: Always be sure you have the right number of AFREZZA cartridges for your dose available before you start. AFREZZA cartridges must only be used with the AFREZZA Inhaler.

Step 1: Select the AFREZZA cartridges for your dose

If your prescribed AFREZZA dose is more than 12 units you will need to use more than 1 cartridge to get your right dose.

Use the dosage chart below to determine the least numberof AFREZZA cartridges you can use for your dose. Othercartridge combinations can be used. Figure B

Select Cartridges Important: Use the AFREZZA dose chart above (see Figure B) to help you choose the right number of AFREZZA cartridges needed for your dose.

Open Packages Remove a buler card from the foil package.Tear along perforation to remove one strip.

Push Cartridges to Remove Remove a cartridge from the strip by pressing on the clear side to push the cartridge out. Remove the right number of cartridges for your dose. Pushing on the cup will not damage the cartridge. AFREZZA cartridges left over in an opened strip must be used within 3 days.

Before Proceeding: Check that you have the right AFREZZA cartridge(s) for your dose.Use only 1 inhaler for multiple cartridges. Throw away your AFREZZA Inhaler after 15 days and get a new one.

Step 2: Loading a cartridge

Hold Inhaler Hold the inhaler level in one (1) hand with the white mouthpiece on the top and purple base on the bottom.

Open Inhaler Open the inhaler by lifting the white mouthpiece to a vertical position.Before you put the AFREZZA cartridge in your inhaler, make sure it has been at room temperature for 10 minutes.

Place Cartridge Hold the cartridge with the cup facing down. Line up the cartridge with the opening in the inhaler. The pointed end of the cartridge should line up with the pointed end in the inhaler.Place the cartridge into the inhaler. Be sure that the cartridge lies flat in the inhaler.

If any of these occur, throw away the cartridge and load a new cartridge.

Close Inhaler Lower the mouthpiece to close the inhaler (this will open the drug cartridge).You should feel a snap when the inhaler is closed.

Step 3: Inhaling AFREZZA

Remove the Mouthpiece Cover Important: Keep the inhaler level during and after removal of the purple mouthpiece cover.

What is the most important information I should know about AFREZZA? AFREZZA can cause serious side effects, including: Sudden lung problems (bronchospasms). Do not use AFREZZA if you have long-term (chronic) lung problems such as asthma or chronic obstructive pulmonary disease (COPD). Before starting AFREZZA, your healthcare provider will give you a breathing test to check how your lungs are working.
What is AFREZZA? AFREZZA is a man-made insulin that is breathed-in through your lungs (inhaled) and is used to control high blood sugar in adults with diabetes mellitus. AFREZZA is not for use to treat diabetic ketoacidosis. AFREZZA must be used with basal insulin in people who have type 1 diabetes mellitus. It is not known if AFREZZA is safe and effective for use in people who smoke. AFREZZA is not for use in people who smoke or have recently stopped smoking (less than 6 months). It is not known if AFREZZA is safe and effective in children under 18 years of age.
Who should not use AFREZZA? Do not use AFREZZA if you: Have chronic lung problems such as asthma or COPD. Are allergic to regular human insulin or any of the ingredients in AFREZZA. See the end of this Medication Guide for a complete ul of ingredients in AFREZZA. Are having an episode of low blood sugar (hypoglycemia).
What should I tell my healthcare provider before using AFREZZA? Before using AFREZZA, tell your healthcare provider about all your medical conditions, including if you: Have lung problems such as asthma or COPD Have or have had lung cancer Are using any inhaled medications Smoke or have recently stopped smoking Have kidney or liver problems Are pregnant, planning to become pregnant, or are breastfeeding. AFREZZA may harm your unborn or breastfeeding baby.
Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins or herbal supplements. Before you start using AFREZZA, talk to your healthcare provider about low blood sugar and how to manage it.
How should I use AFREZZA? Read the detailed Instructions for Use that comes with your AFREZZA. Take AFREZZA exactly as your healthcare provider tells you to.

Signs and symptoms that may indicate low blood sugar include: Dizziness or light-headedness, sweating, confusion, headache, blurred vision, slurred speech, shakiness, fast heartbeat, anxiety, irritability or mood change, hunger. Decreased lung function. Your healthcare provider should check how your lungs are working before you start using AFREZZA, 6 months after you start using it and yearly after that. Lung cancer. In studies of AFREZZA in people with diabetes, lung cancer occurred in a few more people who were taking AFREZZA than in people who were taking other diabetes medications. There were too few cases to know if lung cancer was related to AFREZZA. If you have lung cancer, you and your healthcare provider should decide if you should use AFREZZA. Diabetic ketoacidosis. Talk to your healthcare provider if you have an illness. Your AFREZZA dose or how often you check your blood sugar may need to be changed. Severe allergic reaction (whole body reaction). Get medical help right away if you have any of these signs or symptoms of a severe allergic reaction: A rash over your whole body, trouble breathing, a fast heartbeat, or sweating. Low potassium in your blood (hypokalemia). Heart failure. Taking certain diabetes pills called thiazolidinediones or “TZDs” with AFREZZA may cause heart failure in some people. This can happen even if you have never had heart failure or heart problems before. If you already have heart failure it may get worse while you take TZDs with AFREZZA. Your healthcare provider should monitor you closely while you are taking TZDs with AFREZZA. Tell your healthcare provider if you have any new or worse symptoms of heart failure including: Shortness of breath, swelling of your ankles or feet, sudden weight gain. Treatment with TZDs and AFREZZA may need to be changed or stopped by your healthcare provider if you have new or worse heart failure.

How to take your dose of AFREZZA: Always be sure you have the right number of AFREZZA cartridges for your dose available before you start. AFREZZA cartridges must only be used with the AFREZZA Inhaler.
Step 1: Select the AFREZZA cartridges for your dose

If your prescribed AFREZZA dose is more than 12 units you will need to use more than 1 cartridge to get your right dose.
Use the dosage chart below to determine the least numberof AFREZZA cartridges you can use for your dose. Othercartridge combinations can be used. Figure B

Select Cartridges Important: Use the AFREZZA dose chart above (see Figure B) to help you choose the right number of AFREZZA cartridges needed for your dose.
	Open Packages Remove a buler card from the foil package.Tear along perforation to remove one strip.
	Push Cartridges to Remove Remove a cartridge from the strip by pressing on the clear side to push the cartridge out. Remove the right number of cartridges for your dose. Pushing on the cup will not damage the cartridge. AFREZZA cartridges left over in an opened strip must be used within 3 days.

Before Proceeding: Check that you have the right AFREZZA cartridge(s) for your dose.Use only 1 inhaler for multiple cartridges. Throw away your AFREZZA Inhaler after 15 days and get a new one.

Step 2: Loading a cartridge
	Hold Inhaler Hold the inhaler level in one (1) hand with the white mouthpiece on the top and purple base on the bottom.
	Open Inhaler Open the inhaler by lifting the white mouthpiece to a vertical position.Before you put the AFREZZA cartridge in your inhaler, make sure it has been at room temperature for 10 minutes.
	Place Cartridge Hold the cartridge with the cup facing down. Line up the cartridge with the opening in the inhaler. The pointed end of the cartridge should line up with the pointed end in the inhaler.Place the cartridge into the inhaler. Be sure that the cartridge lies flat in the inhaler.
If any of these occur, throw away the cartridge and load a new cartridge.
	Close Inhaler Lower the mouthpiece to close the inhaler (this will open the drug cartridge).You should feel a snap when the inhaler is closed.
Step 3: Inhaling AFREZZA
	Remove the Mouthpiece Cover Important: Keep the inhaler level during and after removal of the purple mouthpiece cover.

	Exhale Hold the inhaler away from your mouth and fully blow out (exhale).
	Position Inhaler in Mouth Keeping your head level, place the mouthpiece in your mouth and tilt the inhaler down towards your chin, as shown. Close your lips around the mouthpiece to form a seal. Tilt the inhaler downward while keeping your head level.
	Inhale Deeply and Hold Breath With your mouth closed around the mouthpiece, inhale deeply through the inhaler. Hold your breath for as long as comfortable and at the same time remove the inhaler from your mouth. After holding your breath, exhale and continue to breathe normally.

Step 4: Removing a used cartridge
	Replace Mouthpiece Cover Place the purple mouthpiece cover back onto the inhaler.
	Open Inhaler Open the inhaler by lifting up the white mouthpiece.
	Remove Cartridge Remove the cartridge from the purple base.
	Throw away (or recycle) the Cartridge Throw away the used cartridge in your regular household trash.Alternatively, the used cartridge (composed of HDPE, assigned recycling number 2) can be recycled.

Multiple cartridge dosing
If you need more than one (1) AFREZZA cartridge for your dose, see the AFREZZA dosage chart above (Figure B).
Repeat steps 2 through 4 for each AFREZZA cartridge you need for your prescribed AFREZZA dose.

Switching between AFREZZA and injected insulin:
	Contact your healthcare provider before switching insulins. AFREZZA is a mealtime insulin. Do not switch from AFREZZA to a long acting insulin. Do not switch from a long acting insulin to AFREZZA.
