## Description

How quickly does CAPACTION dog flea treatment work? Start killing your dog's fleas in the time it takes to watch one episode of your favorite sitcom. That's right - CAPACTION Oral Flea Treatment starts its job in thirty minutes, providing your dog with immediate relief. Almost all the adult fleas on your dog should be gone within four hours! CAPACTION is a pet flea medicine that can be used once a day if need be, although a single dose should do an effective job.

Review: Ehh - Ordered for my little dog as he was getting fleas so bad, they seemed to work okay, but not killing all of the fleas.. also didn't like that they had to be given almost every 24 hrs.. seems not healthy for my dog. Won't order again.
Review: Works best in combination with monthly flea treatment - Fast acting and Great on flea Infestation. However, it only works on adult fleas and doesn't kill the eggs. This is what you need to know to be satisfied with this product. I use this in conjunction with monthly flea treatment. I first give to my dog, with 30 min to 1 hr. Bath dog in fea shampoo. Treat yard, patio, wash dog bedding and spray with flea spray after the drying cycle. I also spray down the house. Yes you need to do all this especially right before flea season. Some have commented the their dog continues to scratch however you need to understand that they will because they have flea bites all over their body. Think of it like this, getting bit by a mosquito and you scratch and scratch. The saliva of the fleas and or mosquitoes causes you to itch until it heals or you put some kind of soothing ointment, lotion or medication on it. Therefore, I will bath my dog once more in an oatmeal shampoo with in the week. Then I will give another pill 48hrs later then save the rest just in case there is another infestation. This product work well and great in combination of monthly flea treatment that also kills eggs and treat for mosquitoes

## Questions & Answers

**Q: Is there a difference in this box labeled small dog with 11.4mg nitenpyram and the box labeled small dog AND cat with 11.4mg nitenpyram for $10 more?**
A: Only difference is the volume of medication in the pill.  I've been buying Capstar for large dogs >25lbs for 15 years.   I don't own a dog, but my Maine C@@n thinks he's a dog.  I simply cut the 57mg pill into five segments so now I have five 11.4mg doses for my cat.

**Q: how long does the pill work? a month?**
A: Capstar is better used as a solution to an infestation than a preventative flea medication. The pill only works for a few hours. It kills all adult fleas that feed almost immediately. If you have a flea problem in your home, you should give one pill to every pet at the same time for 3 days in a row. Then give again on 7th day, 11th day, and 14th day. One 6 pill package is sufficient per animal. You should also vacuum all carpet daily during the 2 weeks to remove any adult fleas.  Fleas can only live a few days without feeding and the eggs hatch after about 48 hours, so you are stopping them from being able to procreate and without new eggs, there will be no new fleas. I've seen some pretty serious infestations be completely resolved using this method. You should also use a separate monthly prevention treatment to ensure the infestation doesn't return.

**Q: Are the dog tablets the same as the cat ones? The packaging is misleading.**
A: I have given these to both my dog and cat. They are both fine, and they work as long as you keep up your flea regimen. Bathing, Flea sprays Treating yard, topical treatments whatever your regimen may be. I have seen very few fleas on either of my animals since purchasing these tablets. Hope that helps!

**Q: Does this kill ticks too?  Thank you!**
A: No, only adult fleas.
