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

  • 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

  • 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.

  • Gets rid of adult fleas fast
Size: 6 Count
Great flea medication. Cats take to it well. Seems to cure their itchiness. Works well. Good value for money. No weird scents. I administer with a pill shooter, fits well into cap. Recommends following up with a routine flea treatment thats longer lasting, but this is perfect for getting rid of adult fleas. ... show more

  • Victory for the feline front
Size: 6 Count
Ben Says: Bowser, Mario, and Luigi may be cats, but they fought like lions. We do our best to keep the cats flea-free with regular topical treatments, but sometimes those tiny pests stage a comeback. When that happens, it’s time to launch the counterattack — Capstar for Cats. Within hours of dosing, the scratching slowed, and the enemy fell fast. The hardest battle was convincing the cats to actually take the pill — they saw right through my “treat” deception. But once down, it worked beautifully. Fast, effective, and an absolute must for emergency flea warfare. Peace has returned to the kingdom… at least until the next invasion. ... show more

  • Mostly effective, needs to taste better
Size: 6 Count
I like how this flea treatment works quickly, killing fleas in just 30 minutes. It doesn't have a strong odor and doesn't leave any residue on my cat's fur. Plus, it's safe for kittens and cats from 2 to 25 pounds. However, the taste isn't great, and I wish it was more affordable. Also, better availability in stores would help. Overall, a decent product that gets the job done. Product should be a brown color to match kibble and be easier to feed pet. He thought it was part of the plate. ... show more
