Capstar for Dogs (nitenpyram), Fast-Acting Oral Flea Treatment for Dogs Over 25+ lbs, Vet-Recommended Flea Medication Tablets Start Killing in 30 Minutes, 6 Doses

My dog had been dealing with skin irritation and constant scratching for a couple of weeks, especially around her tummy. Nothing seemed to give her relief, and the red spots were getting worse. After using Capstar, I started seeing results within 24 hours. The redness on her tummy became much lighter, and she stopped scratching as much. You could tell her skin was finally starting to heal. I really appreciate how fast-acting this product is—it made a noticeable difference in just one day. Definitely effective and worth it if your dog is struggling with fleas and related skin irritation. Would absolutely use again if needed!

10/10 recommend, it works great. My four dogs were going to itchtown USA pretty much non stop. I spent $90 buying pet armor topical treatments for both my dogs and cats and it didn’t work at all. Both still had fleas and honestly feels like it made it worse. I got pretty desperate and tried this stuff and they itched a little bit for the first and second day but they pretty much have stopped all scratching, and over grooming. Also when I gave them a bath I didn’t find any fleas lol it was like they’d all fallen off? Pretty wild. Either way, use this stuff, bathe your animal the next day and change all bedding everywhere/vacuum everything and you’ll be good to go.

My go to flea medicine for my small dogs. Very easy for them to take, affordable and works great. My dogs love being outside when the weather gets nice, this medicine keeps them protected and it lasts. It's rare I see a flea on them, but if I do I know that will be the only flea because the medicine won't let any others appear. Capstar brand is great for dogs and cats.

Seems to provide relief for symptoms. Pricing is quite high for amount of treatments, so docking a star for that.

First, let me point out that CapStar is NOT a preventative! It is supposed to kill adult fleas on the dog but it doesn't prevent them from getting fleas again - not does it kill anything but adult fleas, which means you still need something (monthly topical or oral flea medicine) to kill the eggs and the larvae or those will obviously mature into adults and you and your pet are stuck in the vicious cycle. That being said, here is my first and only experience with CapStar. We have never had flea issues until this year. I have two Alaskan Malamutes - one 105 pound "short hair" and one 110 pound long hair. Clearly, they both have the Malamute thick double coat. We usually like K9 Advantix II for flea treatment/prevention. Early this summer, I bought the Amazon brand that has the same ingrediens as K9 Advantix II. It arrived with no expiration date and I'm not sure if that's the reason that it doesn't seem to work, that it's not the same formula or perhaps the fleas have become resistant... or it's just an especially overwhelming year for fleas. Either way, I thought by trying this first and THEN putting their prevention on within a day or two, it would work. I gave them each a CapStar pill, nervously watched for adverse reactions and thanked God they didn't seem to have any issues. It also didn't seem to help the flea situation - they continued scratching and biting as before. Because I didn't want to give them back to back, I waited for about 48 hours before giving another CapStar to each of them. Once again, no reaction but the scratching and chewing hasn't subsided at all nine hours later. In fact, I almost feel like both times, they were actually scratching more after the CapStar tablets?? It makes me wonder if it is actually not killing the fleas but just irritating them and making them more active and angry (or at least more hungry LOL). I really needed this to work and was hoping that in conjunction with a topical preventative, we would be able to both kill AND prevent reinfstation with a two prong attack. Sadly, we are just out more money, time and effort. I should mention that along side this effort, I treated the bedrooms that have carpet (the rest of the house has hard floors and we have a no-knap, outdoor rug in the living room because it can be power washed). Anyway, I sprayed the Vet's Best Flea & Tick Home Spray on the carpet, mattresses and washed bedding & blankets. It's difficult to get every possible location that a flea could be hiding but I was fortunate to be able to see a flea and spray Vet's Best directly on it. The Vet's Best spray killed it in less than 10 seconds. It does say that you can apply it to your dog's coat and rub it in down to their skin. That sounded too unrealistic with their thick coats but because it is natural, smells really nice IMO and obviously works, I think I will still attempt that on most of their coat/body, add Diatomaceous Earth to the floors, dog beds, rugs, etc and THEN try reapplying topical prevention. I just have to decide if I am going to use some of the 8 tubes I have left of the Amazon brand or try something else - I might pick up the Frontline Plus that's on sale at Costco tomorrow. *Edit* - I called my vet after posting this review to ask if Frontline Plus was working on fleas in our area (mid-Michgan in lower peninsula). I also spoke with the vet directly when taking this guy (in photo) in for his appointment that fall. The vet said that fleas had become more resistant to topicals and developed a thicker exoskeleton. In her opinion, she said the only thing that was working was oral prevention (like Nexgard). Ultimately, that's what we did - put them both on Nexgard until the cold Michigan winters helped kill the outdoor population and we could all breathe a sigh of relief. We never returned to topicals since this experience but have friends with multiple dogs (2 German Shepherds and a long hair Alaskan Malamute) who continued to use Advantix II (the name brand version) directly from their vet and said they haven't experienced issues. Hope my struggle and experience was helpful in some way but no matter which way you go, I think you can skip the unnecessary step of Capstar and not only save a bit of money but save your dog from extra chemicals that don't offer any real relief or added benefit.

10/10. The fleas literally started dropping off my dogs. We got a random infestation on 4 dogs and they were miserable to say the least. Within a few hours they were already itching so much less and we were seeing the benefit of the medication. I will be buying again to have some just in case for the future!

My two pups somehow got fleas and so I purchased this product but it didn’t get rid of them. I purchased it a second time and it seemed to have helped with the flea issue.

This worked great and started working almost immediately. It was easy to give my dog and helped really fast. I was very happy with how quickly it kicked in.
