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.

  • A Must-Have for Pet Owners
Size: 6 Count
I've been a fan of this product for a while now. It's incredibly effective, and fast acting to boot! The fact that it can kill fleas in just 30 minutes is amazing. The only downside is that it doesn't work on eggs or larvae, just the adult fleas. But honestly, it works so swiftly that you can quickly follow up with any other treatment you prefer, be it drops, a flea dip, or even a flea bath. Despite this minor flaw, I wholeheartedly recommend this product to all pet owners. It's a game changer! ... show more

  • Cat outside, no fleas in or out!
Size: 6 Count
Well, while we can’t keep our 1 and half year old cat inside at this stage, 100% of the time, we had to let him have outside time. Of course, when he came into the house, we saw fleas, or if we combed him outside. It was scary to see so many and with our other cat, he didn’t have that issue and with having cats throughout my life, I guessed that some cats are more likeable to fleas, like some people are more liked by mosquitoes. What was great, with Capstar, was in giving our cat a tablet daily, was that soon, the fleas were gone. It took our cat about two weeks, with daily use. The proof was combing and/or brushing our cat. We could see that the fur didn’t have fleas or the excrement. We also didn’t see the fleas on the bed, carpet, furniture, etc. While it’s a little concerning to give him a tablet lie this, for me, it’s easier than topical. Naturally, I was worried about giving him this tablet daily, since I wasn’t sure how he would react. Initially, he did have a stomach reaction, and started eating grass or tall weeds, right after taking it, though after about a week, he was ok. These days, after longer use, does not have that issue. I do a small modification, though, to give it to him. I don’t put it as a tablet in his throat. I just ‘grind the tablet’ so it’s a powder, then mix it with his favorite liquid cat treat. It mixes with it well. The only time he wouldn’t eat it was when it wasn’t mixed well. (To explain on topicals, while our cat is extremely fastidious, he is constantly getting into shrubs, etc., so a topical isn’t ideal for him. Kudos to those where that works! So…Capstar pills are easy to deal with. They are fairly thin and small, maybe like the size if a thick shirt button. Each pill is individual in a foil, easy to tear off. To grind it to powder, you can use a can or something like it, to get the powder effect. It takes just a little bit of hitting it in the indiviual pill package, in the foil, then open the pill pocket by popping it and put it in the cat dish. It may be in one spot, so mixing it helps. This worked and is wonderful as we love having our cat inside when he needs to be, and allowing him outside, as he has to have his time being in the sun and visiting other outside cats. It also helps, so you aren’t worried about fleas being everywhere in the house. For improvements to the manufacturer, make the product 7 tabs instead of 6, please, and for the larger quantities. Also, find ways to give deals in some way. I know you have a captive audience, though sending some deal is important and appropriate, please. I would say that this, overall, has been helpful for having a cat who seems to be a flea attractor when he is outside and he needs to have his cat roaming, so this is a worthy product to try. His appetite is still great and no side effects after the initial week approx. ... show more

  • Very Effective!
Size: 6 Count
This works to kill present fleas, which is ecspecially useful if a cat is severely infected and works great to use on an outdoor cat before bringing them indoors. However it's not meant to prevent reinfestation as it is very short lived. A monthly topical is still needed but I still use this once or twice a month on my indoor cat anyway as an extra measure because it's so efficient. ... show more

  • Impressed with Fast and Effective Results
Size: 6 Count
I've been pretty happy with this flea treatment. It's truly effective and fast acting. Having 6 doses included is a huge advantage, plus it's safe for cats and kittens. No vet prescription needed is another plus. However, it could use a longer lasting effect. It's also not that easy to find in stores and different flavors for picky cats would be a nice addition. But overall, it's a solid product! ... show more

  • Impressed with the Fast-Acting Solution
Size: 6 Count
This product is terrific. I was thrilled with its effectiveness - it's fast acting, and the fact that 6 doses are included is a big plus. It's suitable for cats weighing 2-25 lbs, easy to administer, and it starts killing fleas in just 30 minutes. What's more? It treats re-infestations, safe for cats and kittens, no vet prescription needed, and suitable for cats 4 weeks and older. I highly recommend it to other cat owners! ... show more

  • I won't buy this again
Size: 6 Count
Just made my cat very sick. Luckily it only lasted one day but if it would have gone into the second day she would have been to the vet. She was lethargic and didn't move from the same spot all day long except to go to the bathroom she also did not eat all day long which is very not normal for her

  • Quick and Effective Flea Treatment
Size: 6 Count
The reason that I like this product is because of its effectiveness. These fast-acting tablets come in six doses, which is a selling point. It's great that it's suitable for cats weighing between 2 to 25 lbs. The fact that it treats re-infestations is a bonus. And the best part? It starts killing fleas in just 30 minutes. I couldn't be happier with this product! ... show more

  • Yes, it really works!
Size: 6 Count
I've tried getting rid of fleas in the past, and i was skeptical as to weather or not this solution could really be this easy and effective. It really is! I can't say i watched dead fleas fall off, I was too grossed out to check, but I can say that I looked a day later and they were all gone. The pill is tiny and easy to administer, no need to cut it in half or grind up. Just toss it in the food and your greedy cat will gobble it up. There were also no side effects or changes in behavior. Everything was normal. Be sure to use with a good flea collar, because there are certainly fleas still hanging out in your cat's favorite lounge spot, and you don't want a secondary infestation. ... show more
