I've been buying Capstar for large dogs >25lbs for 15 years. I don't own a dog, but my Maine C@@n thinks he's a dog. I simply cut the 57mg pill into five segments so now I have five 11.4mg doses for my cat. **Q: how long does the pill work? a month?** A: Capstar is better used as a solution to an infestation than a preventative flea medication. The pill only works for a few hours. It kills all adult fleas that feed almost immediately. If you have a flea problem in your home, you should give one pill to every pet at the same time for 3 days in a row. Then give again on 7th day, 11th day, and 14th day. One 6 pill package is sufficient per animal. You should also vacuum all carpet daily during the 2 weeks to remove any adult fleas. Fleas can only live a few days without feeding and the eggs hatch after about 48 hours, so you are stopping them from being able to procreate and without new eggs, there will be no new fleas. I've seen some pretty serious infestations be completely resolved using this method. You should also use a separate monthly prevention treatment to ensure the infestation doesn't return. **Q: Are the dog tablets the same as the cat ones? The packaging is misleading.** A: I have given these to both my dog and cat. They are both fine, and they work as long as you keep up your flea regimen. Bathing, Flea sprays Treating yard, topical treatments whatever your regimen may be. I have seen very few fleas on either of my animals since purchasing these tablets. Hope that helps! **Q: Does this kill ticks too? Thank you!** A: No, only adult fleas. ## Customer Reviews ### ⭐⭐⭐⭐⭐ More flexible dosing than long-term meds. *by on Reviewed in the United States September 28, 2026* These do the trick, and I prefer a short-duration med to the 1, 3, or 12 month products. That way, if there is a contraindication, it is out of their system within a few days.Note, the fleas clearly don't like these. I've noticed that as they are dying (or jumping overboard?) in the first couple of hours, they increase activity and may make the dog tickle MORE, and become a bit restless. This is a predictable response in our house and has not has any long-term issues. Good idea to lainder dog bedding while the pills attack. ### ⭐⭐⭐⭐⭐ This is a must-have for any dog owner who needs quick *by on Reviewed in the United States October 7, 2025* A Fast-Acting Lifesaver for Immediate Flea Relief!I highly recommend PetArmor CAPACTION (nitenpyram) Oral Flea Treatment for Dogs, Dogs Over 25 lbs (6 Doses). This product is a fantastic solution for dealing with sudden, heavy flea infestations.Speed and Effectiveness (5/5 Stars)The "Fast-Acting" claim is absolutely true. Within 30 to 45 minutes of giving my dog the tablet, the fleas started dropping off him like rain. It’s quite satisfying to see them die that quickly! The immediate relief this product provides is unmatched. It effectively kills the adult fleas currently on your dog, offering instant comfort.Ease of Use (5/5 Stars)The tablets are small and easy to administer. My dog, who is usually picky, took the pill wrapped in a piece of cheese without any issue. Having six doses is very convenient, as it allows you to treat subsequent flare-ups or use it for multiple pets (if they meet the weight requirement).Important Note (What it does NOT do)It is crucial to understand that CAPACTION is an "instant kill" product. It only kills the adult fleas that are on your dog at the time of treatment. It does not have any residual effect. This means it won't prevent new fleas from jumping onto your dog from the environment (carpet, bedding, yard).For long-term protection, you must pair this with a monthly preventative treatment (like a collar, topical spot-on, or another oral medication).Final VerdictThis is a must-have for any dog owner who needs quick, immediate relief from a flea emergency. It's a powerful tool to break the life cycle of fleas fast. Just remember to follow up with a long-term preventative.Overall Rating: 5 out of 5 stars for its purpose (immediate knockdown). ### ⭐⭐⭐⭐⭐ Does exactly what it says. Just for adult thicks and fleas *by on Reviewed in the United States September 7, 2026* Great to kill adults fleas and thick. But you need to find one medicine to prevent for them to keep coming.
