How Quickly Does Revolution Start Working on Fleas and Parasites?
When it comes to protecting your feline friend from parasites, timing is everything. Parasite infestations such as fleas, ticks, and internal worms can escalate quickly, causing discomfort and health risks for your pet. Revolution and Revolution Plus are trusted topical prescriptions designed to combat these parasites effectively and, most importantly, fast.
Understanding Revolution and Revolution Plus
Revolution contains selamectin, a parasiticide that targets a broad range of internal and external parasites in cats. Revolution Plus combines selamectin with sarolaner, adding protection against four types of ticks. Both are applied monthly and are suitable for cats and kittens at least 8 weeks old and weighing over 2.8 lbs.
Speed Matters: How Quickly Does It Work?
The effectiveness of Revolution and Revolution Plus starts rapidly after application. Here’s a breakdown of its action:
- Revolution Plus: Begins killing fleas within 6 hours of reinfestation.
- In studies, it eliminated 100% of adult fleas within 36 hours after application.
- Provides month-long protection against ticks and other parasites.
This quick action is essential in halting the flea life cycle and relieving your pet from itching and potential skin irritations.
Effective Parasite Coverage
Both Revolution and Revolution Plus handle a wide array of parasites, ensuring your cat receives comprehensive protection:
- Fleas (adults and eggs)
- Heartworms
- Ear mites
- Hookworms and roundworms
- Ticks (only with Revolution Plus)
- Flea tapeworms (Revolution Plus indirectly by killing fleas)
Why Quick Action Is Important
Fleas can begin laying eggs within 24–36 hours of landing on a host. Revolution Plus disrupts this timeline by eliminating them before they reproduce. Quick elimination of parasites helps:
- Reduce allergic reactions and dermatitis caused by flea bites
- Prevent further infestations in the home
- Stop the transmission of other parasite-borne diseases
How to Apply for Best Results
To maximize the speed and effectiveness of Revolution or Revolution Plus:
- Use the cap to puncture the tube seal.

- Apply the full contents of the tube directly to the skin.
- Avoid massaging it in or touching the application site.
- Don’t bathe the cat for at least 24 hours post-application.
After 24 hours, the product becomes waterproof, maintaining its efficacy even when your cat grooms or encounters water.
