What It Is and How It Works
Ivermectin is a medication that belongs to the anti-parasitic class of drugs. It functions by interfering with the nerve and muscle functions of parasites, leading to their paralysis and eventual death. By targeting the parasite\’s neural and muscular systems, ivermectin effectively stops the parasite\’s ability to reproduce and spread, thereby alleviating the infection in humans.
Indications / Uses
Ivermectin is primarily approved for the treatment of certain parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal infection)

In some cases, ivermectin may be used off-label for other parasitic infections; however, such uses should always be under the supervision of a healthcare professional, as there are risks and varying levels of evidence for efficacy.

Ivermectin is available in several formulations, including oral tablets and topical creams. Typical dosing varies based on the specific condition being treated, the patient\’s body weight, and other individual health factors.
