How long does dewormer stay in a cat's system?

【Expert answer】
Any Q

Your cat might still have worms after deworming as dewormers take 2-4 days to take effect, or sometimes a second dose is also needed. The worms will usually be gone in 2 to 3 weeks after you give your cat a dewormer. It may need a second deworming a few weeks later to get rid of all the worms. What is this?


How long does the dewormer last?

It can take as little as two hours for the worms to start dying off. However, in most cases, the process starts about 12 hours after administering the dewormer. You may continue to see worms in your pup's poop for about a week. If they had a serious infestation, you may see worms for up to two weeks.

What happens after deworming a cat?

Are there any side effects from deworming medication? Although side effects of dewormer medications are uncommon, some cats may have vomiting, diarrhea, loss of appetite, or increased salivation. These symptoms, if occurred, are usually seen within 24 hours of taking the medication and should spontaneously resolve.

How long does dewormer take to absorb?

Most deworming treatments work in two to six hours after administration. Some medications will dissolve the worms while some will paralyze them. Paralyzed worms pass through the intestinal tract and are passed out in your puppy's poop. This is why you will notice that your puppy poops worms after deworming.

Do cats pass worms after treatment?

After treatment, the tapeworm dies and is usually digested within the intestine, so worm segments do not usually pass into the stool.
