What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to specific chloride channels found in nerve and muscle cells of parasites. This action increases the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasites. It is important to note that ivermectin is not effective against viruses and should not be used for viral infections.
Indications / Uses
Ivermectin is primarily approved for treating certain parasitic infections such as:
- Onchocerciasis: Also known as river blindness, caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: An infection caused by the nematode Strongyloides stercoralis.
Off-label uses have been explored, but they should only be considered under the guidance of a healthcare professional due to varying evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form, often prescribed based on the patient’s body weight. Dosage may vary depending on the specific parasitic infection being treated. It is crucial to follow the prescription label and guidance from a healthcare provider, as factors like kidney and liver function, age, and concurrent medications can influence dosing decisions.

- Take the medication on an empty stomach, at least 1 hour before or 2 hours after a meal.
