Take Action with CapAction

Fleas can be a nightmare—but with CapAction, they don’t have to be. CapAction (nitenpyram) begins killing fleas in just 30 minutes with a single tablet. Just one oral dose stops an infestation right in its tracks.

Starts Killing Fleas in Just 30 Minutes

When it comes to fleas, every minute counts. This fast-acting formula begins working within 30 minutes, so your pet can be free of fleas as soon as possible.

No Rx Needed

CapAction comes in formulations for both dogs and cats, yet no prescription is needed. One dose of CapAction is all it takes to kill the adult fleas on your pet. If those pesky fleas come back and re-infest your pet, don’t worry—CapAction can be safely administered once a day to keep your pet flea-free.

Breaking the Flea Life Cycle

Be patient—it can take months to get rid of a flea infestation, but CapAction is here to help. Here’s how to do it:

1. Treat Your Pets: You can safely administer CapAction as often as once a day to kill adult fleas—treat all your pets to avoid reinfestation.

2. Treat Your Home: Household sprays, powders, and foggers can help kill the fleas hiding in your home.

3. Treat Your Yard: Flea and tick yard sprays will help kill outdoor fleas at the source, so your pet won’t keep bringing them in.

Questions & Answers

18 Customer Questions

Do the cats willingly eat the tablet, or do they have to be pilled?

Answer by Skooby13 • Aug 19, 2025
The pills are tiny, but I crush them and mix them into a pureé lickable cat treat and haven't had any problems with the cats taking the whole dose.

How often do you have to administer. This is a feral cat.

Answer by Chewy • Feb 03, 2021
This treatment starts working quickly and efficiently, killing 90% of adult fleas within 6 hours. A single dose should kill the adult fleas on your cat. In the event of re-infestation, you can safely give your cat another dose as often as once per day.

1/25/21 I want to know is this pill water proof.2 Does the fleas have to bit first. Is this a month long or 1 day medication the website is not very good

Answer by Chewy • Jan 26, 2021
CapAction is an orally administered tablet that does not wash off. Once your pet has swallowed the tablet, the active ingredient, nitenpyram, goes to work within 30 minutes. Once the nitenpyram enters the bloodstream, the fleas ingest it when they bite your pet. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day. CapAction is safe for dogs, puppies, cats, and kittens 2 pounds of body weight or greater and 4 weeks of age or older.

how long does the product last on the cat to treat fleas?

Answer by Chewy • Mar 08, 2022
A single dose of CapAction should kill the adult fleas on your pet. If your pet gets re-infested with fleas, you can safely give another dose as often as once per day. It will begin working within 30 minutes.

On a budget & worried with fleas? Get this!!!

I’ve had a wonderful experience with this treatment and the cost couldn’t be better. It’s nice to have a product that isn’t hundreds even is less than $50 and actually works. The only downside is administering it with a smart cat isn’t easy and it sometimes needs to be daily or weekly. I only switched for a while because of a hair matting issue and I wanted the prescription to get use. Overall, if you’re a cat lover or parent and on a budget get this and he flea/parasite worry free!!!

Worked Immediately!

My poor babies were infested with fleas. Nothing else seemed to work, until getting this. Was a lil worried about oral. No need, the pills are tiny an slathered

My poor babies were infested with fleas. Nothing else seemed to work, until getting this. Was a lil worried about oral. No need, the pills are tiny an slathered with their favorite cat treat, it was easy peasy. Started working within a few minutes. They did do some twitching and a few parkours when the fleas started reacting. I do love that it is safe to use on kittens to seniors. This is now what I will be using if flea treatment is needed.

The lack of awareness and respect.

Not a complaint on chewy, a complaint on FedEx. Delivered 2 boxes to my house, product left in the snow with a clean clear covered porch not 15 feet from where

Not a complaint on chewy, a complaint on FedEx. Delivered 2 boxes to my house, product left in the snow with a clean clear covered porch not 15 feet from where it was delivered. I don't understand how you can be contracted with a company who has no awareness or respect for anyone.

We came home from vacation to find fleas - generally I use natural methods but couldn't get ahead of the problem... I bathed my cats, flea-combed, washed all bedding, theirs and mine! Seeing my 3 cats suffer got to me and I had to make a decision on something to knock down the fleas on my cats while continuing treatment on all areas at home. This product does what it claims! I crushed a pill for each cat placing it in wet food, spaced out over 1 hour apart, so glad I did! My first kitty- 18 lb pixie-bob - went Crazy running around and it Was hard watching, and unable to console him, but after about 40 minutes he went and laid in the bathroom sink and slept peacefully. My other 2 kitties didn't have such a rough time with it but Dead Fleas were found where the cats were and when I brushed each of them. I held back on giving a second dose next day but if needed it's good to know this works! Just please read all info on pkg and treat all other areas at the same time.

Fleas just started showing up

My indoor cat somehow caught fleas. I don't know how long she's had them but I noticed her scratching more and when I went to pet her I saw one scurry. I only saw one but I hate bugs so I've got her a flea collar which didn't work out. It stunk and we weren't seeing any improvement on the scratching and also weren't seeing fleas. I decided to buy this product and give her one pill. About 15 fleas popped up within a half hour. Great product

Effective!

This is not a monthly flea med fyi! This kills current fleas in 24-48hr time span. It works great during a flea infestation followed with a monthly treatment! No

How fast it arrived

This product kills any live flea within about 30 min. It works great for my cat because he is allergic to flea saliva and every bite matters! You can give this product

This product kills any live flea within about 30 min. It works great for my cat because he is allergic to flea saliva and every bite matters! You can give this product every day if need be, but I use it at the end of his 30 day treatment because it always eats off before 30 days. He has a week where he starts getting bit again at around week 3. Crazy how sick fleas make him and he licks all his hair out because of it and licks sores that cause secondary infections. It really is a lot for the cat.

Between this and the other brand I noticed no differences really. My stray cat which I’ve brought inside has stopped scratching, and I haven’t found any fleas in the house since (several weeks ago).

This product works great, but keep in mind that it is not for long term flea control. This is kill the adult fleas within about 30 minutes. In my experience it works best in addition to a topical flea repellant a day or two after you give this medication.

Cheaper than Capstar

I mashed these up and mixed it with food. They would not eat any of it so it must taste awful. I gave it all to them already as community cats. Maybe that will help
