What It Is and How It Works
Ivermectin is an antiparasitic medication. It works by binding to glutamate-gated chloride channels found in the nerve and muscle cells of parasites, leading to increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. This mechanism effectively reduces the symptoms of parasitic infections and helps the body\’s immune system clear the organism.
Indications / Uses
Ivermectin tablets are primarily used to treat certain types of parasitic infections:
- Onchocerciasis (River Blindness): Caused by infection with the parasite Onchocerca volvulus.
- Strongyloidiasis: Caused by the roundworm Strongyloides stercoralis.
While some have explored its use for other conditions, such off-label uses should be considered cautiously and only under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, with the 3mg tablet being the most common for human use. Dosing depends greatly on the condition being treated, the patient\’s body weight, and individual health considerations such as liver function and concurrent medications.
Pediatric dosing is determined by weight and should only be done under medical supervision. Special populations, like those with liver issues or pregnant women, require tailored dosing strategies that take into account potential risks and benefits.
