What It Is and How It Works
Ivermectin is an antiparasitic medication that binds to chloride ion channels in nerve and muscle cells of parasites, leading to paralysis and death of the parasites.

While primarily targeting parasite infections, its effects on human neural cells are minimal, which contributes to its safety when used appropriately under medical guidance.

- Onchocerciasis (river blindness)

While some have speculated on ivermectin\’s potential in treating viral infections, such use should be approached cautiously and only under professional medical guidance due to the lack of robust evidence supporting such treatments.

Ivermectin is most commonly available in tablet form, but it can also be found as a topical cream or lotion for skin conditions. The typical dosing for oral ivermectin varies based on the condition being treated, patient weight, and severity of the infection. It is essential to follow the healthcare provider’s prescription. Factors such as liver or kidney impairment, pregnancy, and concurrent medications can influence dosing and should be assessed by a healthcare professional.
