Revolution Plus vs Stronghold Plus for Cats: Which Is Better?
Finding two nearly identical parasite treatments with different names can leave any cat parent confused. In this Revolution Plus vs. Stronghold Plus comparison, we explain what these two products have in common, how they differ, and exactly what you need to check before purchasing either one.
Perhaps your veterinarian recommended Revolution Plus, but you found Stronghold Plus online at a much more attractive price. The packaging looks similar; both are monthly topical treatments, and both are produced by the same pharmaceutical company, Zoetis.
So, is there any meaningful difference between them? Let’s dive into the science.
The Direct Answer: Are They the Same?
For most cat parents comparing Revolution Plus vs. Stronghold Plus, there is no meaningful difference in their core medical effectiveness. They are regional twin medications.
Both products contain the exact same two active ingredients in matching weight-based strengths:
- Selamectin: Helps control fleas, ear mites, roundworms, hookworms, and immature heartworm larvae.
- Sarolaner: Belongs to the isoxazoline group of parasite treatments, adding robust flea, tick, and mite activity.
The corresponding tubes of both products deliver a matching minimum dose of approximately 6mg/kgof selamectin and 1mg/kgof sarolaner when used according to their approved weight categories.
However, they should not be described as identical in every single respect. Their approved parasite claims, packaging, prescription status, and instructions can vary depending on the country in which they are sold.
Side-by-Side Comparison
Because they share the same active ingredient foundation, their core coverage profiles are nearly identical.

While the core protection against these six major parasite categories is the same, the exact tick species and additional parasites named on their labels differ by region.
For example, the U.S. Revolution Plus label lists specific tick species approved for treatment and control based on local U.S. data. Meanwhile, the current UK Stronghold Plus information explicitly includes biting lice and notoedric mange among its authorized regional uses. These variations simply reflect the specific studies reviewed and claims approved by veterinary regulators in each distinct market.
⚠️CRITICAL WARNING: Stronghold Is Not the Same as Stronghold Plus
Do not confuse Stronghold Plus with plain Stronghold when ordering online.
Stronghold Plus contains both selamectin and sarolaner (matching Revolution Plus). Plain Stronghold contains only selamectin, not sarolaner, so it does not provide the same tick coverage. Always check that the word “Plus” appears prominently on the packaging before ordering.
Why Do They Have Different Names?
The biggest difference between these two products is simply regional branding and authorization.
Revolution Plus is the name used in the United States and Australia. Stronghold Plus is authorized under that name in the UK, Europe, and selected international markets. Zoetis changes the names to comply with local trademark laws and regional veterinary regulations.
These regional differences frequently include:
- Weight displayed in pounds (lbs) vs. kilograms (kg)
- Package design and tube colors
- Approved regional tick species listed on the box
- Country-specific safety instructions and package sizes
- Local prescription and import requirements
These variations do not mean that one product is weaker or stronger than the other; they mean that each product must be used according to its own approved packaging and local veterinary guidelines.
The Real Difference: Price, Availability
When comparing Revolution Plus vs. Stronghold Plus online, price is often the main reason shoppers consider the international product. Stronghold Plus may sometimes cost less because of regional pricing, currency differences, distribution arrangements, and open competition between international pet pharmacies.
Is It Safe to Switch Between Them?
Because the products contain the exact same active ingredients in corresponding dose strengths, a veterinarian may consider them comparable treatment options.
However, do not apply Stronghold Plus immediately after Revolution Plus or use both products during the same monthly treatment period. Overlapping doses could expose your cat to more medication than intended.
Before making a switch, always confirm:
- When the previous dose was applied (maintain a strict 30-day gap).
- Your cat’s current weight (moving into a higher weight range may require a different tube strength).
- Whether your cat has previously reacted to either active ingredient.
- Whether heartworm protection has been interrupted.
For kittens, both products are generally intended for use from eight weeks of age, subject to the minimum body weight printed on the regional packaging.
Important Safety Considerations
Both products contain sarolaner, which belongs to the isoxazoline class. Isoxazoline medicines have been associated with neurological reactions such as tremors, poor coordination (ataxia), and seizures in a small percentage of animals.
Revolution Plus should be used cautiously in cats with a history of neurological disorders, and the Stronghold Plus label lists convulsions as a very rare reported reaction.
Other possible reactions may include:
- Temporary hair loss or changes to the coat at the application site
- Redness or itching
- Lethargy or reduced appetite
- Drooling, vomiting, or diarrhea
Contact a veterinarian promptly if your cat experiences a severe or persistent reaction. Additionally, the safety of these products has not been fully established in pregnant, nursing, or breeding cats. Use in these animals should be discussed with a professional first.
How Do They Compare With Longer-Lasting Treatments?
Both products are normally applied monthly. However, some cat owners prefer a treatment with a longer interval between applications to avoid the hassle of monthly spot-ons.

Frequently Asked Questions
Are Revolution Plus and Stronghold Plus the same medicine?
Yes. They contain the exact same active ingredients—selamectin and sarolaner—in corresponding tube strengths and are made by the same manufacturer (Zoetis). However, their approved regional uses, packaging language, and prescription rules differ by country.
Does Stronghold Plus cover the same main parasites?
Yes. Both treatments cover the same six core parasite categories: fleas, ticks, ear mites, roundworms, hookworms, and heartworm disease. Exact species and certain additional claims vary by regional label.
Is Stronghold Plus a generic version of Revolution Plus?
No. Stronghold Plus is an official Zoetis regional brand name, not an unrelated generic copycat flea medicine.
Can I apply Stronghold Plus right after using Revolution Plus?
No. Do not overlap the treatments. Maintain your strict 30-day schedule. Confirm the next application date with a veterinarian if you cannot remember when the last dose was given.
Do these products treat tapeworms?
They do not directly treat an existing adult tapeworm infection. Their flea-killing activity reduces the risk of flea-transmitted tapeworms (Dipylidium caninum), but a cat with an active infection will need a separate deworming medicine.
Can indoor cats use these treatments?
Yes. Indoor cats can still encounter fleas brought in on your clothes, mosquitoes carrying heartworm larvae that enter through open windows, or mites carried by other household pets.
Final Verdict
The Revolution Plus vs. Stronghold Plus decision is mainly about regional branding, availability, pricing, and local veterinary regulations. Neither option is automatically more effective because they share the same chemical DNA.
Choose the correct product for your cat’s exact weight, purchase exclusively from a trustworthy supplier, and avoid overlapping monthly doses. When changing products or restarting interrupted heartworm protection, always confirm the treatment schedule with your veterinarian.
