What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to glutamate-gated chloride ion channels in the nerve and muscle cells of parasites. This binding increases permeability to chloride ions, leading to paralysis and death of the parasite. In humans, ivermectin is used to manage infections caused by various parasitic worms and external parasites.
Indications / Uses
Ivermectin is primarily approved for the treatment of certain parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal infection caused by roundworms)
Off-label, it has been used for other parasitic infections under professional supervision. The appropriateness of off-label use should be carefully discussed with a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets and topical formulations. The dosing of ivermectin is highly dependent on the specific condition being treated, patient weight, and other individual factors. It is crucial to follow healthcare provider instructions and prescription labels carefully.
