What It Is:
Revolution® is the brand name for selamectin, a topical parasiticide applied once a month at the base of a cat’s neck. It provides broad-spectrum protection against fleas, heartworm, ear mites, and certain ticks, as well as some intestinal parasites. Revolution® is prescription-only and is approved for use in cats and kittens six weeks of age or older.
🐾 What It Treats and Prevents
Revolution® protects against:
- Adult fleas (kills fleas before they lay eggs)
- Heartworm disease (prevents development of heartworm larvae)
- Ear mites (Otodectes cynotis)
- Cheyletiella mites (“walking dandruff”)
- American dog tick (Dermacentor variabilis) on cats
- Roundworms (Toxocara cati) and hookworms (Ancylostoma tubaeforme) when given monthly
It is often chosen for multi-parasite control in a single, convenient application.
🧪 How It Works
Selamectin, the active ingredient, is absorbed through the skin and distributed systemically. It interferes with parasite nerve and muscle function, leading to paralysis and death of susceptible parasites. Because it reaches multiple tissues, Revolution® can control both external and some internal parasites.
🐾 How to Use It
Revolution® is applied once every 30 days year-round:
- Remove one tube from the package
- Part the fur at the base of the neck between the shoulder blades
- Place the opening of the tube directly on the skin and squeeze out all contents
- Do not bathe or swim your cat for 24 hours after application
Always use the cat formulation and dose based on your cat’s weight. Treat all cats in the household to prevent reinfestation.
🔍 Safety and Precautions
Revolution® is generally safe, but observe for:
- Mild irritation or hair loss at the application site
- Excessive grooming if your cat licks the site immediately after application
- Rare systemic reactions such as vomiting, diarrhea, or lethargy
Use with caution in cats with:
- Known hypersensitivity to selamectin or formulation ingredients
- Under six weeks of age or weighing less than the minimum weight on the label
- Severe skin conditions at the application site
If adverse signs persist beyond 24 hours, contact your veterinarian.
🩺 Prognosis
With proper monthly use:
- Flea infestations are rapidly controlled, with most adult fleas killed within 24 hours
- Heartworm larvae are prevented from maturing into adult worms
- Ear mites and other mites** are eliminated within a few weeks
- Intestinal roundworms and hookworms are reduced when given monthly
Revolution® becomes more effective over consecutive months of continuous use.
