What It Is and How It Works
Ivermectin is an antiparasitic agent commonly prescribed to treat various worm infections, specifically onchocerciasis and intestinal strongyloidiasis. The mechanism of action involves binding to glutamate-gated chloride ion channels in parasites, leading to paralysis and death of the organism. It is selective for parasites and does not affect human neurons in the same way.
Indications / Uses
The approved uses of ivermectin include treatment of parasitic infections such as:
- Onchocerciasis: Also known as river blindness, primarily found in parts of Africa and sharing a vector (black fly) which facilitates transmission.
- Strongyloidiasis: An intestinal infection caused by the roundworm Strongyloides stercoralis.
Off-label, ivermectin has been explored for various uses, including scabies and lice, and has been a subject of interest for other indications. Always discuss off-label use with a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is mainly available in oral tablet form but can also be found in topical solutions for head lice and certain skin conditions.
