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.

  • Easy cat flea prevention.
Size: 6 Count
It does the trick, my cats do better with this medication, tubes of topicals don't work for them, and it is far easier to crush the tabs and mix it with their favorite food or with toppers. They will eat every drop, and the capstar tabs without any nonsense or struggle. It works. A good addition to your flea prevention program Effectiveness: Florida is rife with fleas, and this product works. It is cost-effective also. ... show more

  • It works on adult flees only
Size: 6 Count
Looks like it's working. My cat might be allergic to flees. She doesn't tolerate topical flee and tick poison. For all the people worh bad reviews: this poison is safer than monthly vet poison. It has downsides - only lasts few hours, only kills adult flees, can cause side effects. Good thing is - if your cat has side effects, they will resolve in few hours. So if you don't know life cycle of the flees, you might want to look it up. Nitenpyram is effective, kills many insects including cockroaches and mosquitoes. It kills mites too btw. But it doesn't last long. ... show more

  • Instant Relief for Flea Infestations – A Must-Have for Pet Owners!
Size: 6 Count
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.

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

  • Effective and Quick Flea Treatment
Size: 6 Count
I've been pretty happy with this flea treatment. The six doses in one pack are quite convenient. The fast-acting nature of the treatment is a huge plus. It's great that I can give it as often as once a day, and it's safe for cats and kittens from 2 to 25 lbs, which offers much-needed flexibility. However, I wish the effect lasted longer and the taste was improved for easier administration. All in all, a good product. ... show more

This product has been a game changer. The six-dose pack is a great deal. It's a quick treatment, effective in killing fleas, and can be given daily to cats aged 4 weeks and older. It's safe for cats and kittens from 2-25 lbs, and treats re-infestations, killing fleas within 30 minutes. No vet prescription needed. Highly recommended for cat owners! ... show more

  • Instant Flea Relief for Cats
Size: 6 Count
CAPSTAR (nitenpyram) Oral Flea Treatment for Cats works super-fast. Crushed pills (between 2 spoons) and mixed with soft food, the cats ate without hesitation and digestive side effects. Within an hour of ingesting the cats show some improvement less digging & scratching irritations by the next morning they looked significantly happier. Unfortunately, the duration isn't that long (about 2.5 days), but for instant relief from flea infestations especially with difficult to handle cats it's a game changer in providing them with relief. ... show more

  • THEY WORK
Size: 12 Count
I would have given a 5-STAR if not for being ripped off. These work great, BUT, I ordered a 2-pak and only received "1" box...was charged $64 for 6 pills instead of 12!!! I wrote to the seller, NO RESPONSE & thete's nowhere to ask for help. EXTREMELY DISAPPOINTED IN MY PURCHASE!! The product is really useful though & they do kill fleas right away. If you use these along with treating your lawn with triazicide you'll rid yourself of fleas for a year. We give a pill every other day for at least a week or so. I have 7 cats and not one of them has ever had an adverse reaction to the CapStar pill. ... show more

Doesn't work as well as it used to, but that might just be my own paranoia. Easy to administer.
