Quick Facts Scannable
- Ivermectin is used to treat parasitic infections such as river blindness and scabies.

What It Is and How It Works
Ivermectin belongs to a family of antiparasitic agents known as avermectins. It combats parasitic infections by targeting the glutamate-gated chloride channels found in the nerve and muscle cells of invertebrates. This action inhibits the influx of chloride ions, leading to paralysis and eventual death of the parasite.
While highly effective against various parasites, ivermectin does not directly treat bacterial or viral infections. Its antiparasitic action relies on disrupting the neurological processes of parasites without significantly affecting the host through off-target effects.
Indications / Uses
Ivermectin is primarily approved for treating multiple parasitic infections, including:
- Onchocerciasis: Commonly known as river blindness, it is caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An infection resulting from the Strongyloides stercoralis parasite.
- Scabies: A skin condition caused by Sarcoptes scabiei mites.
While ivermectin has been explored for other medical uses, such as certain viral infections, these applications remain contested and require further validation through clinical trials and regulatory approval.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets, topical creams, and injectable solutions. Dosing is highly individualized, taking into account factors such as the type of infection, patient weight, and overall health status.
For adults, a common dose might be a single oral dose based on body weight in kilograms. Children and individuals with specific health conditions may require adjusted dosages. Always follow the prescription and advice given by your healthcare provider.
How to Take It Correctly Step-by-Step
Proper administration of ivermectin is crucial for efficacy and safety. Here is a general guide:
- Take ivermectin on an empty stomach, at least 1 hour before or 2 hours after meals.
- If a dose is missed, take it as soon as you remember, unless it is almost time for the next dose. Do not double up doses.
- Store tablets in a cool, dry place, away from direct sunlight.
- Avoid consuming alcohol while taking ivermectin.
Adhering to the regimen prescribed by your healthcare professional is critical. Avoid sharing medication with others or using it beyond its intended scope.
