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.

  • Get the adult fleas off FAST
Style: 6 Count Size: 2-25 lbs
You will probably read a few reviews letting you know that the fleas moved around after falling off. They may not die instantly, but they are dying. I have been using this product for some time, but I have never had an infestation as bad as this year. I am of course combining this with an oral flea medicine from the vet to make sure it is good and strong. However here's a Pic of the fleas that fell off in jsut the first hour. That's like 27 fleas. And my dogs is sleeping so good. In a bit he will get a bath to extract the rest and a dose of this every day for a few days to keep them all dead. ... show more

  • Great while you wait for Prescription Meds
Style: 6 Count Size: 2-25 lbs
I have visiting dogs with me for a month and while I wait to get them seen by my vet for Bravecto these are amazing! You have to administer it daily and you want to keep your dogs contained as the fleas literally fall off of them (and most that fall off don't seem dead so you need to deal with that as well). I followed up with a rosemary flea shampoo and this has been a lifesaver! ... show more

  • Efficient and radical!
Style: 6 Count Size: 2-25 lbs
When I just adopted my puppy, we went to Sonoma and the person that hosted us didn’t tell us that her house was infested by fleas. I woke up to my puppy screaming in the middle of the night, and I didn’t even need a light, the parasites were crawling all over her. Of course, it happened on a Sunday, and the following day was July 4th, so the three veterinarian and pet stores within a 50 miles radius were closed. Thank GOD for Amazon, that delivered this product. As she was a puppy, she could only have half a dose, and even that was too much. But after 12hours of torture, she eventually got a break from the monsters and was able to sleep. All this to say, after using this product for a year now, as I constantly battle with fleas all year round because both my cats are outdoorsy, this is the most efficient and fast remedy I’ve found for my dog. Although, as efficient as it is, it is not a full remedy against fleas, and has to be completed with anti flea treatments, full house eradication and thorough shower with adequate anti flea shampoos of all your pets. I took one star off because even though this product has done wonders, I feel like over time the fleas have built a resistance against it and is now after a year not as efficient ... show more

  • Kills fleas
Style: 12 Count Size: Over 25 lbs
This product is amazing I have tried everything to rid my dogs of fleas. I researched how to kill fleas on my dog and this product was recommended. I looked on Amazon and they had it so I ordered a package and found within an hour the fleas were dying. I didn't realize how many were on the dogs they were so infested. Now after 3 days they are wagging their tails again and wanting to play. I am so satisfied with this product I will never use anything else again. Great product highly recommend it. ... show more

  • Didn't work at all for Alaskan Malamutes
Style: 6 Count Size: Over 25 lbs
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 ingredients. 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 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 are 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 a long 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 I'm 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 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 cost/body, add Diatomaceous Earth to the floors, dog beds, rugs, etc and THEN try reapplying topical prevention. I just have to decide of I am going to use some of the 8 tubes I have left of the Amazon brand or try something else - might pick up the Frontline Plus that's on sale at Costco tomorrow. ... show more
