What It Is and How It Works
Ivermectin is an antiparasitic that is effective against a range of internal and external parasites in animals and humans. In humans, it works by binding to glutamate-gated chloride channels, which leads to increased permeability of cell membranes to chloride ions. This action results in paralysis and death of the parasite, effectively clearing the infection from the host body.
While it primarily targets parasitic infections, its mechanism of modulating specific ion channels has raised interest in other potential therapeutic areas, though these uses are still under investigation and should only occur under strict medical supervision.
Indications / Uses
Ivermectin tablets are chiefly used for the treatment of:
- Strongyloidiasis: A parasitic disease caused by Strongyloides stercoralis, prevalent in tropical and subtropical areas.
- Onchocerciasis (\ »River Blindness\ »): A disease caused by infection with the parasitic worm Onchocerca volvulus, causing severe itching and skin changes, with potential for blindness.
Though some off-label uses have been discussed, such as potential antiviral properties, they should be approached with caution and discussed with a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in tablet form for human use. Typical dosing varies based on the condition being treated and patient-specific factors such as weight, age, and kidney or liver function. Ivermectin tablets are dosed based on body weight and usually recommended as a single dose, but follow your healthcare provider\’s instructions or prescription label. Special populations, including those who are pregnant, breastfeeding, or have liver/kidney disease, require careful dosing considerations.
