What It Is and How It Works
Ivermectin is a well-established antiparasitic drug. It works by binding to proteins in the neuronet cells of parasites, leading to increased membrane permeability, paralysis, and death of the parasite. This mechanism primarily affects invertebrates, making it effective against worms and certain external parasites like lice and mites. For human applications, it is most commonly prescribed in its oral form for the treatment of intestinal strongyloidiasis and onchocerciasis (river blindness).
Indications / Uses
Ivermectin is indicated for the treatment of:
- Intestinal strongyloidiasis: An infection caused by the parasitic worm Strongyloides stercoralis.
- Onchocerciasis: Also known as river blindness, caused by the Onchocerca volvulus.
- Scabies and head lice: Mild-to-moderate off-label use under specialist supervision.
Recent attention has turned toward its potential use in treating other infections, including viral infections, but these uses are under investigation and not approved by regulatory authorities without strict clinical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablets, topical creams, and lotions. Dosing varies based on the condition being treated, patient weight, and other health factors:

- Older adults or those with liver issues may require dosing adjustments.
Always follow the prescription label instructions or consult your healthcare provider for personalized dosing recommendations.
