What It Is and How It Works
Ivermectin is an anti-parasitic agent that works by binding to certain chloride channels in nerve and muscle cells of parasites, leading to paralysis and death of the parasite. This mechanism helps clear parasitic infections like onchocerciasis and strongyloidiasis.
Indications / Uses
For humans, ivermectin is approved for treating specific parasitic infections, such as:
- Onchocerciasis (river blindness)
- Intestinal strongyloidiasis
- Scabies, in some cases, particularly resistant or severe forms
Off-label, ivermectin has been explored for other parasitic infections and conditions, but such uses should only be pursued under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form for human use, with several strengths. Dose and duration depend on the specific infection, patient weight, and clinical guidelines. For any condition, follow healthcare provider instructions closely. Factors like liver or kidney function and interactions with other medicines are important considerations in determining the appropriate dose.
How to Take It Correctly Step-by-Step

- Take ivermectin on an empty stomach with a full glass of water.
