What It Is and How It Works
Ivermectin is an antiparasitic medication that works against a variety of parasites. The drug attaches to the parasite\’s nerve and muscle cells, leading to paralysis and eventual death of the parasite. This action helps to clear the infection from the body. While primarily used for parasites, its potential effects are being studied in other conditions, although current evidence and regulatory approvals for such uses remain limited.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections, including:
- Onchocerciasis: Also known as river blindness, caused by the worm Onchocerca volvulus.
- Strongyloidiasis: Infection by the roundworm Strongyloides stercoralis.
- Other parasitic infections: Including certain types of lice and scabies under specific guidelines.
Off-label uses have been explored but should only be pursued under the guidance of a healthcare professional due to the necessity of safe and evidence-based prescribing.
