Heartgard FAQs - Everything You Need to Know

Heartgard helps to protect our cats and dogs against the ever-looming threat of heartworm infection. Keeping our pets safe from this potentially life threatening disease, Heartgard can be a great way to arm your pet against these vile creatures, but it helps to know all the facts before putting your pet on any new medication. Here are the answers to some of the most common questions about Heartgard.

“Can You Get Heartgard Without a Prescription?”

No. Heartgard is only available with a prescription. Contact your vet and get your pet protected today.

“What is the Generic of Heartgard?”

The only active ingredient in Heartgard is ivermectin, but there are no other heartworm medications besides Heartgard that contain only ivermectin. There are, however, other, branded generics that use ivermectin, along with other deworming drugs, like Tri-Heart Plus and Iverhart Max

“What Are the Side Effects of Heartgard?”

Heartgard might cause vomiting, diarrhea, and moderate depression in rare cases. Chances of having an adverse reaction increase in Collie type breeds and Australian Shepherds, due to a genetic inability to properly metabolize ivermectin.

“Where Can I Find Heartgard Coupons?”

Heartgard typcially has a special offer available and PetCareRx is constantly offering deals on all sorts of flea & tick and heartworm medications. Head to our Heartworm products page to check out our current promotions.

“What is the Difference Between Heartgard Plus vs Heartgard?”

Heartgard Plus uses the same heartworm killing medicine, ivermectin. The 'plus' in Heartgard Plus indicates the inclusion of pyrantel pamoate, which paralyzes and kills other intestinal worms, such as hookworms and roundworms.

“What Are Some Good Heartgard Alternatives?”

While most heartworm medications use the same active ingredient, ivermectin, to get rid of heartworm, there are a few that don't.

Sentinal Flavor Tabs, which prevent both heartworm AND fleas, uses milbemycin oxime and lufenuron.

Selamectin, the only active ingredient used in Revolution, provides topical treatment against heartworm, roundworm, hookworm, fleas, ear mites, scabies, and ticks.

Trifexis provides protection against heartworm, fleas, and other intestinal worms, using spinosad and milbemycin oxime.

Finally, Advantage Multi provides a topical solution to fleas, mites, heartworms, and other intestinal parasites, using the active ingredients of imidacloprid and moxidectin.
