What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to glutamate-gated chloride ion channels, which are vital for the nerve and muscle function of parasites. This binding leads to paralysis and death of the parasite. While effective against certain types of parasitic infections, its mechanism does not specifically target viral infections such as COVID-19.
Indications / Uses
The primary approved use of ivermectin includes the treatment of:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Scabies
- Head lice (topical form)
While some have considered ivermectin for COVID-19, this use is off-label and lacks strong evidence. Off-label use should only occur under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including:
- Oral tablets
- Topical creams and lotions
- Injectable formulations (for veterinary use)
Dosing depends on the specific infection being treated, patient age, weight, and other medical conditions. Always follow the prescription label and consult a healthcare provider for guidance.

When taking ivermectin, adhere to the following guidelines:
- Take the medication on an empty stomach with water.
- If a dose is missed, take it as soon as remembered unless it is close to the next dose. Do not double the dose.
- Store at room temperature away from moisture and heat.
- Do not share your medication with others.
