What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat infections caused by specific parasites. It binds to chloride ion channels in nerve and muscle cells of parasites, disrupting their normal function. This mechanism leads to increased cellular permeability, muscle paralysis, and death of the parasite.
Indications / Uses
Ivermectin\’s primary approved uses include treating parasitic infections such as:
- Onchocerciasis: Infection caused by the parasite Onchocerca volvulus, also known as river blindness.
- Lymphatic Filariasis: Caused by Wuchereria bancrofti and other species, leading to severe disability.
- Strongyloidiasis: An infection by Strongyloides stercoralis, a parasitic worm.
While ivermectin has been studied for off-label uses, such as treating COVID-19, these applications are controversial and not widely supported by clinical evidence. Always follow local health guidelines and consult healthcare professionals regarding such uses.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available mainly in oral tablet form. Dosing is generally based on the patient\’s weight and the particular condition being treated. Typical dosing can range from a single dose to repeated doses over specific periods, as determined by a physician. Modifications may be necessary for individuals with liver impairments or other specific health concerns. Professional guidance is essential for accurate dosing.
How to Take It Correctly
When taking ivermectin tablets:
- Take on an empty stomach, typically one hour before breakfast.
- If a dose is missed, take it as soon as remembered but avoid doubling doses.
- Store the medication at room temperature away from light and moisture.
