What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to a class of drugs known as anthelmintics. It works by binding to specific proteins to paralyze and eventually kill the parasites. For certain conditions, such as onchocerciasis and strongyloidiasis, it affects the nerve and muscle functions of the parasites, leading to their death.
Indications / Uses
Ivermectin is primarily approved for the treatment of various parasitic infections. The most common uses include:
- Onchocerciasis: Also known as river blindness, caused by the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: A roundworm infection affecting the intestines.
- Scabies: A skin infection caused by mites, treatable with ivermectin when topical treatments fail.
Off-label uses are infrequent and should only be pursued under the guidance of a healthcare professional, as research is ongoing about their efficacy.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms including tablets, topical lotions, and creams. The appropriate dosage depends on the form and the condition being treated:
- Tablets: Commonly used for parasitic worm infections; dosing is usually weight-based.

- Topical Lotions: Utilized for treating skin conditions like lice infestations.
Dosing considerations will vary based on individual factors such as kidney and liver function, age, and interactions with other medical conditions and medications. Therefore, it is imperative to follow the prescription label and advice of a healthcare provider.
