Precautions:

Do not dispense dose applicator tubes without complete safety and administration information. Avoid oral ingestion. Cats may experience hypersalivation, tremors, vomiting and decreased appetite if Barrier  for Cats is inadvertently administered orally or through grooming/licking of the application site. The safety of Barrier  for Cats has not been established in breeding, pregnant, or lactating cats. The effectiveness of Barrier for Cats against heartworm infections (D. immitis) after bathing has not been evaluated in cats. Use of this product in geriatric patients with subclinical conditions has not been adequately studied. Several otherwise healthy, thin geriatric cats experienced prolonged lethargy and sleepiness after using this drug. (See ADVERSE REACTIONS.)

Adverse Reactions:

Field Study:Following treatment with imidacloprid and moxidectin topical solution or an active control, cat owners reported the following post-treatment reactions:

* These three cats were from the same household and included one 13-yr-old cat in good health, one 15-yr-old FIV positive cat in good health, and one 15-yr-old, underweight cat in fair health. Lethargy was noted for 24 to 36 hrs after the first treatment only; one cat was unsteady at 48 hrs. These cats were not on other medications.
OBSERVATION	Imidacloprid and Moxidectin Topical Solution n = 113	Active Controln = 38
Lethargy (protracted sleeping, poorly responsive)	3 cats* (2.7 %)	None observed
Behavioral changes (e.g., agitated, excessive grooming, hiding, pacing, spinning)	9 cats (8.0 %)	1 cat (2.6 %)
Discomfort (e.g., scratching, rubbing, head-shaking)	5 cats (4.4 %)	None observed
Hypersalivation (within 1 hour after treatment)	3 cats (2.7 %)	None observed
Polydipsia	3 cats (2.7 %)	None observed
Coughing and gagging	1 cat (0.9 %)	None observed

During another field study, a 16-year-old cat with renal disease slept in the same place without moving for two days following application. (See PRECAUTIONS.)

Laboratory Effectiveness Studies: Imidacloprid and moxidectin topicl solution was administered at the recommended dose to 215 cats in 20 effectiveness studies. One random-sourced cat exhibited signs consistent with either moxidectin toxicity or viral respiratory disease and died 26 hours after product application; necropsy findings were inconclusive as to the cause of death. A second cat that became ill 3 days after application of imidacloprid and moxidectin topical solution responded to treatment for respiratory infection and completed the study. A third cat became ill on day 3 and died with signs and lesions attributable to panleukopenia on day 7 after moxidectin application.

Post-Approval Experience: The following adverse events are based on post-approval adverse drug experience reporting. Not all adverse reactions are reported to FDA CVM. It is not always possible to reliably estimate the adverse event frequency or establish a causal relationship to product exposure using this data. The following adverse events in cats are uled in decreasing order of reporting frequency: hypersalivation, depression/lethargy, application site reactions (alopecia, pruritus, lesions, and erythema), decreased appetite, vomiting, hyperactivity, ataxia, trembling, and behavior disorder (hiding).

In some cases death has been reported.

In humans, ocular and dermal irritation, nausea, numbness or tingling of the mouth and lips, anaphylaxis, pruritus, vomiting, and tongue/taste abnormalities have been reported following exposure to this product.

The recommended minimum dose is 4.5 mg/lb (10.0 mg/kg) imidacloprid and 0.45 mg/lb (1.0 mg/kg) moxidectin, once a month, by topical administration.

Do not apply to irritated skin.

1. Remove one dose applicator tube from the package. As specified in the following table, administer the entire contents of the Barrier for Cats tube that correctly corresponds with the body weight of the cat.

* Cats over 18 lbs. should be treated with the appropriate combination of Barrier for Cats tubes.
Cat (lbs.)	Volume (mL)	Imidacloprid (mg)	Moxidectin (mg)
2–5	0.23	23	2.3
5.1–9	0.4	40	4
9.1–18*	0.8	80	8

2. While holding the tube in an upright position, twist the cap to break the seal and then apply. The cap will remain on the tube.3.Part the hair on the back of the cat’s neck at the base of the head, until the skin is visible. Place the tip of the tube on the skin and apply the entire contents directly on the exposed skin. Lift tube away from skin before releasing pressure on tube. 



3. Part the hair on the back of the cat’s neck at the base of the head, until the skin is visible. Place the tip of the tube on the skin and apply the entire contents directly on the exposed skin. Lift tube away from skin before releasing pressure on tube.

Do not get this product in the cat's mouth or eyes or allow the cat to lick the application site for 30 minutes. Treatment at the base of the head will minimize the opportunity for ingestion by grooming. In households with multiple pets, keep animals separated to prevent licking of the application site.

Stiff, matted hair or a damp, oily appearance of the hair may be observed at the application site on some cats. This is temporary and does not affect the safety and effectiveness of the product.

Heartworm Prevention: For prevention of heartworm disease, Barrier for Cats should be administered at one-month intervals. Barrier for Cats may be administered year-around or at a minimum should start one month before the first expected exposure to mosquitoes and should continue at monthly intervals until one month after the last exposure to mosquitoes. If a dose is missed and a 30-day interval between doses is exceeded, administer Barrier  for Cats immediately and resume the monthly dosing schedule. When replacing another heartworm preventative product in a heartworm prevention program, the first treatment with Barrier for Cats should be given within one month of the last dose of the former medication. At the discretion of the veterinarian, cats older than 6 months of age may be tested to determine the presence of existing heartworm infection before treatment with Barrier for Cats (See ADVERSE REACTIONS – Post-Approval Experience).

Flea Treatment: For the treatment of flea infestations, Barrier for Cats should be administered at one-month intervals. If the cat is already infested with fleas when the first dose of Barrier for Cats is administered, adult fleas on the cat will be killed. However, re-infestation from the emergence of pre-existing pupae in the environment may continue to occur for six weeks or longer after treatment is initiated. Cats treated with imidacloprid, including those with pre-existing flea allergy dermatitis have shown clinical improvement as a direct result of elimination of fleas from the cat.

Ear Mite Treatment: For the treatment of ear mites (Otodectes cynotis), Barrier for Cats should be administered once as a single topical dose. Monthly use of Barrier for Cats will control any subsequent ear mite infestations.

Intestinal Nematode Treatment: For the treatment and control of intestinal hookworm infections caused by Ancylostoma tubaeforme (adults, immature adults and fourth stage larvae) and roundworm infections caused by Toxocara cati (adults and fourth stage larvae), Barrier for Cats should be administered once as a single topical dose.
