Description

Capstar (nitenpyram) is a fast-acting flea treatment tablet for use in dogs and cats that starts killing fleas in only 30 minutes. A single dose of Capstar kills 90% of adult fleas within 4 hours for dogs and 6 hours for cats, ridding your pet of these pesky parasites. Capstar is for dogs, puppies, cats, and kittens 2 pounds of body weight or greater and 4 weeks of age or older. Key Features Capstar is for dogs, puppies, cats and kittens 2 pounds of body weight or greater and 4 weeks of age and older. Dosing Capstar is available in 2 dosages: Cats and dogs from 2 to 25 pounds (11.4 mg) Dogs from 25.1 - 125 pounds (57 mg) Administration To give Capstar tablets, place the oral tablet directly in your pet’s mouth or hide it in food. Use with Other Medications If your pet is currently receiving a monthly or longer-lasting flea preventative medication but still becomes infested with fleas, it is safe to administer Capstar to address a flea infestation. Capstar may also be used together with other products, including heartworm preventatives, corticosteroids, antibiotics, vaccines, deworming medications, and shampoos. Re-infestations Capstar kills adult fleas on dogs and cats, offering quick relief for your furry friend. While Capstar works fast to kill adult fleas and alleviate a current infestation, a subsequent preventative solution is recommended to prevent future re-infestations from any existing flea eggs and larvae in the environment. If you notice more fleas have found their way onto your dog or cat in the days following treatment, continue treating your dog or cat with Capstar with up to one dose per day. Important Safety Information Capstar is safe to use in puppies and kittens 4 weeks of age and older, and 2 pounds of body weight or greater. Always read, understand, and follow the label and use directions.

    • This stuff really works!
Size: 6 Count
I use capstar when needed for a feral cat community I feed. I mash it up and place it in the food ( try to mix it in the top of the wet food to make sure it’s eaten) and it really helps. There’s one cat that seems to have a flea allergy and he scratches to the point where he has patches of hair missing from all the scratching. The first time I gave it to him, his hair grew back within 2 weeks. Unfortunately I have to do this more regularly since I can’t control the flea exposure. Regardless, it’s the best way to help ferals and strays with flea problems (I don’t think they can taste it in the food). It’s a bit expensive but worth it for me. I haven’t seen any bad reactions and overall it’s pretty safe to use even for nursing momma cats. Been using it for over a year now and will continue to do so. Highly recommend! ... show more

Size: 6 Count
Review Image by Heaven Heaven
Review Image by Heaven Heaven
We recently tried the CAPSTAR (nitenpyram) Oral Flea Treatment for our pets, and it has been a game-changer in dealing with flea infestations. As a pet owner with multiple animals, flea treatments are essential, and this product provides fast, effective relief for our furry friends. Fast-Acting and Highly Effective What stands out about CAPSTAR is how quickly it works. After just a single dose, we saw immediate results. Within 30 minutes, fleas were dropping off our pets, and within a couple of hours, the infestation was significantly reduced. It’s perfect for those times when your pets need instant relief, especially if you’re dealing with an active flea problem. Safe and Easy to Administer This treatment is incredibly easy to give to our pets. The pills are small and can be given either directly or mixed with food. Both of our pets had no problem taking it, and it didn’t cause them any distress. The oral formula is safe and gentle, so we didn’t have to worry about harsh side effects. Works Quickly Between Other Treatments While this treatment doesn’t provide long-term flea prevention, it is an excellent quick-fix for an immediate infestation. It works well when paired with a monthly flea preventive to ensure your pets stay flea-free in the long run. It’s perfect for situations when you need fast relief before starting a longer-term flea prevention routine. Great Value for the Price For the results it delivers, the CAPSTAR Flea Treatment is a great value. It’s affordable and effective, especially for pet owners who are dealing with sudden flea issues. One dose is enough to take care of the problem, making it a practical option for those who need quick action. Final Verdict: A Must-Have for Fast Flea Relief If you’re looking for immediate, fast-acting flea relief for your pets, CAPSTAR Oral Flea Treatment is the product to choose. It’s effective, easy to administer, and works quickly to eliminate fleas, providing much-needed comfort for your pets. ✔ Pros: Fast-acting, easy to administer, effective, safe for pets ✘ Cons: Doesn’t provide long-term prevention (but works well with other treatments) Would I buy it again? Yes, especially for quick flea relief! ... show more

    • Works fast but only a couple days
Size: 6 Count
Works fast but read fine print. Only lasts a few days. No negative side effects on all our pets but need something that lasts a full month. Will go back to applying the liquid to the back of their neck. Good value for the price if you only need something that works fast and lasts a couple days.

    • Excellent buy for immediate relief!
Size: 6 Count
This ABSOLUTELY works!!! It was NO exaggeration when I read that you will see dead fleas fall off your cats. I have two - one 14 yrs of age with extremely dense hair so fleas are hard to catch or even see - i noticed flea dirt on her though and her scratching more - so i gave her a pill - about an hour or two later, she was sitting on a pillow next to me - she got up and i noticed 5 or 6 dead fleas on the pillow - so an EXCELLENT buy. I also noticed on my second cat a couple from where she was sleeping as well. This worked amazingly - but remember - you have to use another flea prevention as well as this does not kill larvae or eggs! I was okay with that as I just wanted something immediately to give my babies some relief and this absolutely did so. After reading side effects - my cats did both have bursts of energy followed by extensive cleaning (i took mine outside and brushed them to help with itching), followed by extreme lethargy - these were all listed side effects btw - and after about 5 hours - they were back to their perky but also cat nap like selves. DEFINITELY worth the money for instant relief for your babies!!!! ... show more

    • 1 pill on my chubby cat worked within an hr.
Size: 6 Count
I didn't even know we had a flea problem until I started noticing her scratching alot and then started seeing "black dots" in her fur when I brushed her. No bites on me 🤷. Not once. Other customers were not lieing! Lol. Tried this for the 1st time after reading reviews. The fleas literally start jumping ship within an hr of giving it to her. My kitty is a lil chubby and this worked great. She loves tuna. I heard in the reviews some cats did not like it, or they were put down the cats throat, so to be sure not to waste money (cause it's not cheap) I waited till she was nice and hungry at dinnetime, crushed up 1 pill (they are tiny) and mixed it in with about 2 Tbs tuna and a tiny bit of water. She is picky and she ate it all up. About 1hr later started running around, itching like crazy, even meowing like a a deep meeeow like she was not happy at all. I put her in my room and closed to the door while I sprayed the furnature with a flea spray. About an hr later went to let her back out. There were 2 adult fleas on my bed. 1st time ever seeing the buggers! Sprayed them a few times but they did die. When I let her out she went and hid behind the TV entertainment center in the corner for about another hr. Came out on her own looking much happier. I am following up with a second pill in a couple of days to a week, then a 3rd dose in 2 or 3 weeks. I also bought her some natural chewable treats that naturally repel bugs. Lots of great reviews on those as well. ... show more
