Prescription Heartworm Prevention

Chewy carries multiple brands of Heartworm medicine for dogs including Heartgard, Interceptor, Tri-Heart, Sentinel, Trifexis, and Revolution. Most heartworm medicine uses the active ingredient Ivermectin to kill the immature form of the heartworm while also helping to control intestinal worms.

Heartworm disease can be devastating to your pet’s health, and the best possible heartworm treatment is actually prevention—which means it’s crucial to take preventive measures like choosing a monthly prescription heartworm medicine for your cat or dog.

Thanks to the Chewy Pet Pharmacy, you can keep your pal protected year-round with an assortment of targeted, veterinarian-prescribed heartworm medicines that are formulated to help prevent heartworm in cats or dogs, including kittens and puppies. Heartworm prevention is available in oral heartworm treatments like flavored chewable tablets and soft chews that are easy to give as a treat, and they also come in single-dose liquid that’s applied topically to the skin and fur—which is great for cats that are not very fond of medicines. Of course, for kitties, you can always slip a tablet inside a cat pill pocket to turn the medication into a treat.

These FDA-approved heartworm treatments are the same ones you’d get at your vet’s office. They contain active ingredients that work by eliminating the immature stage of the heartworm parasite, even if your pet has already been exposed through an infected mosquito. Each pill or single-dose tube is formulated to work for up to a month. Heartworm medicine must be given monthly without missing a dose in order to continue offering heartworm protection all year long.

Most heartworm treatment products come with six doses to provide six-month coverage, which means you need to be sure to select the appropriate amount to keep your pal protected year-round. Best of all, you can have it delivered to your door—all you need is a veterinarian’s prescription. When it comes to preventing heartworm, make sure to consult your veterinarian so you can select a monthly heartworm prevention treatment that’s right for you and your pal.

To keep your pets healthy indoors and outdoors, make sure you choose the heartworm prevention medicine that is formulated for your pet’s age and weight. At the Chewy's online pet pharmacy, you can find flavored heartworm tablets and chews, plus topical liquids for cats and dogs that are 2 pounds to 100 pounds, so you can be sure to find the right one to suit your fur baby’s proportions—from the mini to the mightiest. Make sure to pick up a prescription flea and tick medicine too for more complete protection from biting pests. Chewy Pharmacy makes it easy—just add all your essentials to your cart, like dog treats, cat food, cat litter or dog toys, along with your prescription pet medications.
