Quick Facts About Ivermectin
- Primarily used to treat certain parasitic infections such as onchocerciasis and intestinal strongyloidiasis.
- Works by paralyzing and killing parasitic organisms.

What It Is and How It Works
Ivermectin works by binding to specific ion channels in the nerve and muscle cells of parasites. Specifically, it targets glutamate-gated chloride channels, causing an increase in permeability to chloride ions and resulting in the paralysis and death of the parasite. It is particularly effective against certain parasitic worms and topical infestations like head lice.
Indications / Uses
Ivermectin is mainly indicated for the treatment of parasitic infections like:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal threadworm)
- Scabies
- Pediculosis (lice)
Off-label use has been considered in the context of COVID-19; however, scientific consensus and clinical guidelines do not uniformly support its efficacy or safety for this indication. Consult a healthcare professional before considering off-label uses.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including:
- Oral tablets
- Topical creams and lotions
- Injectable forms (primarily for veterinary use)
The typical dosing depends on the condition being treated, patient weight, age, and any comorbid conditions. Patients with liver issues, elderly patients, or pregnant women should consult their healthcare providers for individualized dosing advice. Always follow the prescription label or instructions from your healthcare provider over general guidelines.
How to Take It Correctly Step-by-Step
