What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to a class called avermectins. Its primary function is to bind onto the nerve and muscle cells of parasites, causing paralysis and eventually leading to their death. This action prevents the parasites from reproducing and spreading, effectively eradicating the infection in the host body. Ivermectin is particularly effective against infections caused by roundworms, threadworms, and other specific parasites.
Indications / Uses
Ivermectin is approved for use in treating several parasitic diseases. These include:
- Onchocerciasis: Also known as river blindness, caused by Onchocerca volvulus.
- Strongyloidiasis: A condition caused by a type of roundworm known as Strongyloides stercoralis.
- Scabies: Skin infestation caused by the mite Sarcoptes scabiei.
- Lice: Infestations caused by head lice or other lice species.
It is important to note that while ivermectin has been discussed for potential off-label uses, such applications should only occur under the supervision of a healthcare professional due to varying evidence and guidelines.

- Oral Tablets: Commonly used for systemic infections such as onchocerciasis and strongyloidiasis. Dosage may depend on body weight and type of infection.
