What It Is and How It Works
Ivermectin is classified as an antiparasitic agent. It works by binding to certain proteins in the nervous system of parasites, leading to increased permeability of their cell membranes to chloride ions. This causes paralysis and eventually the death of the parasites. Ivermectin is particularly effective against parasites that attach to human intestines or skin.
Indications / Uses
Commonly used for treating:
- Intestinal strongyloidiasis (intestinal worms)
- Onchocerciasis (river blindness)
- Head lice and scabies
Off-label uses may include investigations for certain viral infections, although this is still under scientific study and should only be considered under strict medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in oral tablet form. The dosing can vary significantly based on the age, weight, and medical condition being treated. Always follow the specific dosing instructions provided by a healthcare professional. Adjustments may be necessary for patients with liver impairments or those taking other medications.
