What It Is and How It Works
Ivermectin is an antiparasitic medication. Its primary mechanism involves binding to chloride ion channels in the nerve and muscle cells of parasites. This leads to increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. This mechanism is effective in treating parasitic infections such as onchocerciasis and strongyloidiasis.
Indications / Uses
Ivermectin is primarily used for treating parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Lice infestations

Off-label, it has been scrutinized for potential antiviral properties, though more evidence is needed for such applications. Patients should only use it as directed by a healthcare provider for approved conditions.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including 3 mg and 6 mg tablets, topical creams, and injectables. The appropriate dosage depends on the condition treated, patient weight, and other factors such as kidney/liver function and co-morbid conditions.
