FAQ:

Q: Which heartworm medicine is the best?

A: Treating for heartworm means killing the worms in the dog’s heart. The drug melarsomine is what will kill heartworms in dogs. The vet gives this drug in a series of deep intramuscular injections, and it’s very effective against adult heartworms. Melarsomine is called an adulticide.

Q: What is the safest effective flea medication?

A: Afoxolaner (Brand name NexGard) Fluralaner (Brand name Bravecto) Nitenpyram (Brand names include CapStar) Spinosad (Brand name Comfortis)

Q: Does heartworm Meds kill all worms?

A: Monthly heartworm medications work by killing heartworm larvae before they develop into adults. In addition to heartworms, many of these products kill other parasitic worms such as roundworms, hookworms and whipworms, as well as other insects and parasites such as fleas, ticks and mites.

Q: What is the best heartworm treatment?

A: Treatment for heartworm involves the administration of two medications. Melarsomine —administered through a series of injections—eradicates adult worms, and ivermectin kills the microfilaria (larval stage). Additionally, a vet may prescribe antibiotics or steroids, depending on the stage and severity of infection.
