Ivermectin is a medication used to treat parasitic infections. It belongs to the class of drugs known as antiparasitic agents and works by paralyzing the nervous system of parasites, resulting in their death.

Ivermectin is most commonly used to treat infections caused by roundworms, threadworms, and other parasites. It is also effective against scabies and lice infestations. In veterinary medicine, ivermectin is used to treat heartworms and other parasites in dogs and other animals.

Recently, there has been controversy surrounding the use of ivermectin as a treatment for COVID-19. While some studies have suggested that ivermectin may have potential therapeutic benefits for COVID-19 patients, the evidence is limited and conflicting, and the drug has not been approved for this use by regulatory agencies.

It is generally well-tolerated, but common side effects include nausea, diarrhea, and skin rash. In rare cases, it can cause more serious side effects such as liver damage or allergic reactions.
