What It Is and How It Works
Ivermectin is a medication primarily used to treat parasitic infestations.

This action leads to paralysis and death of the parasites, effectively treating the infestation. Ivermectin does not work directly on viruses or bacteria and is not an antibiotic.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections, including:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An intestinal infection caused by the Strongyloides stercoralis worm.
- Scabies: A skin condition caused by the Sarcoptes scabiei mite.
- Head Lice: Infestation by the Pediculus humanus capitis louse.
Off-label uses have been explored, but these should only be considered under healthcare provider supervision due to varying evidence and safety concerns.

Dosing is highly individualized based on factors such as the patient’s weight, the specific infection, and other health conditions. It is critical to follow the prescribed dosing regimen and consult a healthcare provider for personalized instructions.
