What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the avermectin class. It functions by binding to specific ion channels in nerve and muscle cells of parasites, leading to paralysis and death of the parasite. While it effectively treats a variety of parasitic infections in humans, its use for non-parasitic conditions is more complex and subject to ongoing research. It\’s important to understand the mechanism primarily targets parasites and not human cells, contributing to its therapeutic benefit with a favorable safety profile.
Indications / Uses
Ivermectin is mainly indicated for the treatment of infections caused by certain parasites. Approved uses include:
- River blindness (Onchocerciasis): Caused by the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: An infection caused by the roundworm Strongyloides stercoralis.
- Scabies: A skin condition caused by mites, treatable with topical formulations.
- Occasionally used off-label for other parasitic conditions under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets and topical formulations. Dosage depends on the type of infection, severity, and patient-specific factors:
- Oral tablets: Commonly used for internal parasitic infections, adjusted according to body weight.
- Topical gels or creams: Used for skin conditions such as scabies; dosage varies by formulation.
Healthcare professionals consider age, liver/kidney function, potential interactions, pregnancy, and breastfeeding status when determining dosing.
