How Long Does Revolution for Cats Last?
Revolution for cats is a popular topical medication designed to prevent and treat various internal and external parasite infestations. Its effectiveness and convenience make it a trusted choice among pet owners and veterinarians alike. But how long does it actually last, and why is it vital to administer it on schedule?
Monthly Protection and Coverage Duration
Revolution, whose active ingredient is selamectin, provides one month of protection from the date it is applied. This month-long protection includes:
- Adult fleas – kills existing fleas and prevents reinfestation
- Flea eggs – stops the life cycle by preventing hatching
- Heartworm disease – prevents the development of heartworms
- Ear mites, roundworms, and hookworms – treats and controls infestations
For a cat to be fully protected year-round, monthly application of Revolution is essential. Missing a dose could leave your cat vulnerable to potentially harmful infections and infestations.
Revolution vs. Revolution Plus
There are two formulations of the product:
- Revolution: Contains selamectin and is primarily effective against fleas, heartworms, ear mites, hookworms, and roundworms.
- Revolution Plus: Combines selamectin with sarolaner for broader coverage, including ticks and greater efficacy against fleas. This formulation also protects against flea tapeworms by killing fleas that may carry them.
Like the original, Revolution Plus also provides month-long protection and should be reapplied every 30 days to maintain effectiveness.
How Fast Does It Work?
- Revolution starts killing fleas within hours and eliminates most of them within 36 hours.
- Revolution Plus expands on that with action beginning within 6 hours of reinfestation and maintains 100% flea kill efficacy for 5 weeks.
This fast action helps stop the flea life cycle and reduces the chance of developing related skin conditions or tapeworms.
Administration Schedule and Instructions
To ensure continual protection, Revolution should be applied:
- Once a month
- On the same day each month, or adjust based on when the last dose was applied if a dose is ever missed
Proper application involves:
- Parting the fur at the base of the neck
- Applying directly to the skin using the entire content of the tube
- Avoiding washing or bathing the cat for 24 hours post-application, after which the product remains waterproof
This routine ensures optimal coverage. Always dispose of the used tubes safely and wash hands after application.
Weight-Based Dosage
The effectiveness for a full month is based on accurate dosing for the cat’s weight:
- Cats < 5 lbs: 15 mg of selamectin
- 5.1–15 lbs: 45 mg of selamectin
- 15.1–22 lbs: 60 mg of selamectin
Veterinarians will prescribe the proper dosage, and it's important not to exceed or underestimate it.
Impact of Missed Doses
Missing a dose can result in lost protection. If forgotten, apply the medication as soon as possible and then resume the regular monthly schedule. Never double the dose to make up for a missed one.
Key Safety Considerations
- Safe for cats at least 8 weeks old and weighing over 2.8 lbs (1.27 kg)
- Side effects are rare but may include mild skin reactions, lethargy, or digestive disturbances
- Do not use in sick or underweight cats or those with known neurological issues, especially with Revolution Plus
- Humans should avoid contact with the product and wash exposed skin immediately if touched
Storage Guidelines
- Store below 30°C (86°F)
- Keep out of reach of children and animals
- Revolution is flammable and should stay in its original packaging
Conclusion
Revolution and Revolution Plus each provide effective 30-day protection against a variety of parasites. To keep your feline friend safe from fleas, ticks, worms, and more, stick to a consistent monthly application schedule. This routine, combined with proper dosage and usage, helps ensure your pet stays healthy and happy all year round. Always consult your veterinarian to find the right protection plan for your cat's specific needs.
