What It Is and How It Works
Ivermectin is an antiparasitic agent belonging to the avermectin class. It works by binding to specific chloride channels in the nerve and muscle cells of parasites, which increases the permeability of the cell membrane, leading to paralysis and death of the parasite. This mechanism does not affect human cells in the same way, which accounts for its selective toxicity towards parasites.
Indications / Uses
Ivermectin is approved for treating several parasitic infections, such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Certain lice and scabies infestations
Off-label uses, including the treatment of COVID-19, have not been supported by sufficient clinical evidence and should only be undertaken under strict medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form, often prescribed in a single dose based on body weight. The exact dosage should always be determined by a healthcare provider. Factors such as age, weight, liver function, and concurrent medication may influence dosing decisions. Pregnant or breastfeeding women and individuals with liver disease require special dosing considerations.
