What It Is and How It Works
Ivermectin is an antiparasitic medication that operates by binding to chloride ion channels in parasites’ nerve and muscle cells, leading to paralysis and death. This action is effective against various parasites affecting humans, but the mechanism means it is not effective against viruses or bacteria.
Indications / Uses
Approved uses of ivermectin include treatment for:
- Strongyloidiasis: A parasitic infection caused by a roundworm.
- Onchocerciasis (River Blindness): Caused by the worm Onchocerca volvulus and transmitted by blackfly bites.
- Scabies and Lice: When other treatments fail or are not advisable.
Some off-label uses have emerged, but these should only be considered under professional supervision due to limited and mixed evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available as oral tablets and topical creams. Dosing typically depends on the type and severity of the infection, patient weight, and other health considerations.
- Adults: Dosing is often weight-based, and specific conditions may require repeated doses.

All dosing should follow prescription labels and recommendations from healthcare professionals.
