What It Is and How It Works
Ivermectin is an anti-parasitic medication that belongs to the class of drugs known as anthelmintics. It works by binding to certain proteins in the parasites, causing an increase in the permeability of the cell membrane to chloride ions. This results in paralysis and death of the parasites. In humans, it is primarily used to treat specific parasitic infections.
Indications / Uses
Ivermectin is FDA-approved for the treatment of several parasitic infections:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An intestinal infection caused by the Strongyloides stercoralis parasite.
- Scabies and lice (off-label): While not officially approved for these uses, ivermectin is sometimes prescribed to treat these conditions.
Off-label use of ivermectin for viral infections is controversial and requires medical supervision. It is crucial to rely on clinical guidance for such treatments.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several dosage forms, including oral tablets and topical creams. The dosing regimen depends on the condition being treated, patient age, weight, and health status.
Patients with liver or kidney issues, special populations like children or the elderly, or those who are pregnant or breastfeeding require cautious dosing and professional guidance.
