Get 6-in-1 Parasite Protection with Revolution Plus



Protect Against Fleas, Worms & Mites with Advantage Multi


Prescription Worm Medicine for Cats

Help your cat get rid of internal pests with parasite & deworming medicine. Chewy has a great selection of prescription deworming medicine including tapeworm medicine, roundworm and hookworm treatment, and ringworm medicine. We also have combination products that get rid of several types of worms at once.

Most types of prescription worm medicine come as oral medications in tablet, chewable tablet, or soft chew form. Many treat tapeworms, roundworms, hookworms and whipworms, as well. These treatments can protect for a month or more and help break the cycle of parasite reinfection.

In addition to deworming pills, you can get prescription parasiticides to treat conditions like mange and ear mites. Some of these are long-acting topicals that protect against fleas and ticks, too. Cats with ringworm will require an antifungal medicine and not a dewormer, since ringworm is not actually caused by a worm.

One of the most important prescription cat medicine formulas you will need is heartworm medicine. See your vet for a heartworm test and prescription and remember to give your kitty her medication year-round. You can find everything you need to keep your furry friends healthy in the Chewy pet pharmacy. Shop for cat parasite medicine, worm medicine for dogs, preventative flea and tick products and everything else to keep your best friend pest-free healthy. Chewy has vet-recommended parasite & deworming medicine and so much more!

Frequently Asked Questions about Prescription Worm Medicine for Cats

How do I get cat parasite and deworming medicine prescriptions online at Chewy Pharmacy?

Get cat parasite and deworming medicine prescriptions online at Chewy Pharmacy by first visiting your vet for an exam and the necessary tests. Your vet can then prescribe medication for you to order online from our pharmacy. Simply add your pet’s name and vet information at checkout and we will contact your vet for the prescription. That’s all you need to do to order your cat deworming and parasite medicine prescriptions from Chewy!

What is cat dewormer?

Dewormer treats roundworms, hookworms and whipworms by paralyzing and killing them, while tapeworms are killed and broken into smaller sections your cat can then pass. Some parasites, like hookworms and whipworms, are so small you may not see them in your cat’s stool at all. That is why you should visit your vet regularly and have her perform an exam and test your cat’s stool for parasites.

How do I set up Autoship for my prescription cat parasite and deworming medicine?

Set up Autoship for your prescription parasite and deworming medicine by choosing Autoship when you check out. Then, select your delivery frequency—you can always cancel or change this at any time. You must have a valid prescription or refill on file for Autoship to occur. If you do not have a prescription, or if your prescription is close to expiring, one of our team members will contact your vet to obtain the necessary information. Autoship makes getting deworming and parasite medicine for your cat fast and easy!

Does cat dewormer cause diarrhea?

Dewormers can cause diarrhea and frequent defecation is a common side effect, too. The symptoms usually pass within a day or two and your kitty should be back to feeling normal by then, as well. Common side effects from dewormers include diarrhea, excessive salivation, vomiting or hair loss at the application site for topicals. Talk to your your vet if any side effects cause you concern.

What prescription cat deworming and parasite medicine is best?

The best prescription deworming and parasite medicine for your feline will depend on which parasites or worms she has and what other problems you want to prevent or treat. Preventatives like Heartgard and Interceptor Plus protect against heartworm and treat and control intestinal worms, as well, while NexGard and Bravecto protect against fleas and ticks that can carry parasites. You can also buy standalone dewormers and targeted treatments for problems like mange, mites and ringworm. Ask your vet which products might be best for your cat.
