What Is Ivermectin?

Ivermectin is an antiparasitic medication that belongs to a class of drugs known as anthelmintics. It works by interfering with the nervous system and muscle function of parasites, leading to paralysis and death of the organisms.

In humans, ivermectin has been approved and widely used for treating various parasitic infections, particularly those caused by roundworms and ectoparasites.
