What It Is and How It Works
Ivermectin is an anti-parasitic medication that works by disrupting the nerve and muscle functions of parasites, leading to their paralysis and eventual death. This mechanism of action primarily affects parasites without significantly impacting human cells, which makes it an effective treatment option for several parasitic infections.
Indications / Uses
Ivermectin is primarily approved for the treatment of:
- Onchocerciasis (River Blindness): A disease caused by infection with the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: An infection by the intestinal roundworm Strongyloides stercoralis.
Off-label uses have been explored but should be approached cautiously and only under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form for oral administration. Proper dosing depends on the patient\’s weight, the specific condition being treated, and other individual factors such as liver function and concurrent medications. It\’s crucial always to follow the dosage prescribed by a healthcare provider and not to self-adjust.
