Additional Information
Precautions
- Minimum Age and Weight: Do not use in cats under 9 weeks of age or weighing less than 2 lbs.
- Sick or Underweight Cats: Never apply Barrier to sick, debilitated, or underweight cats regardless of their age or current body weight.
- Breeding, Pregnant, Lactating Cats: Safety has not been established in breeding, pregnant, or lactating cats; always consult your veterinarian before use.
- Geriatric Cats: Use with caution in older cats that may have undiagnosed underlying health conditions and consult your veterinarian first.
- Licking Prevention Critical: Accidental ingestion or licking of the product may cause hypersalivation, tremors, vomiting, and decreased appetite in cats.
- Bathing Efficacy Not Evaluated: Effectiveness against heartworm after bathing has not been evaluated; avoid bathing the cat close to application time.
- Keep Children Away: Children should not come into contact with the application site for at least 30 minutes after applying.
- Eye Irritant for Humans: Avoid eye contact, wash hands thoroughly after handling, and flush eyes with water immediately if accidental contact occurs.
Possible Side Effects
- Hypersalivation: Excessive drooling can occur if the cat grooms the treated area; applying at the head base reduces licking access.

- Tremors: Neurological tremors have been reported following accidental ingestion of the product; contact your veterinarian immediately if this occurs.
- Application Site Reactions: Stiff, oily hair at the application site may appear temporarily; this is cosmetic and does not affect product safety.

Frequently Asked Questions
Q1: What does Barrier Topical Solution (Purple Box) treat and prevent in cats?
Ans: This is a monthly spot-on treatment for cats that prevents heartworms, eliminates adult fleas, treats flea problems, controls ear mites, and handles roundworm and hookworm infections in kittens and adult cats over 9 weeks old.
Q2: How does Barrier for Cats compare to Advantage Multi for Cats?
Ans: Barrier for Cats contains the same active ingredients as Advantage Multi, 10% imidacloprid and 1% moxidectin, at identical concentrations. Both are FDA-approved monthly prescription topicals offering equivalent five-in-one parasite protection, with the primary difference being the brand name and price.
Q3: How do the two active ingredients in Barrier for Cats work?
Ans: Imidacloprid targets the nervous system of fleas, causing paralysis and rapid death within 12 hours of application. Moxidectin is absorbed into the bloodstream after topical application, where it disrupts the nervous systems of heartworm larvae, roundworms, and hookworms, preventing development and eliminating existing infections.
Q4: Can Barrier be used in cats weighing more than 18 lbs?
Ans: For cats over 18 lbs, an appropriate combination of Barrier tube sizes should be used to reach the correct dose, as directed by your veterinarian. Never use a single Purple Box tube alone for cats exceeding 18 lbs without veterinary guidance.
Q5: Is the monthly cat spot-on safe for pregnant or lactating cats?
Ans: Barrier for Cats has not been tested for safety in breeding, pregnant, or nursing cats. If your cat is in any of these stages, talk to your vet before starting parasite prevention.
