What It Is and How It Works
Ivermectin is an antiparasitic agent belonging to the macrocyclic lactone class. It works by binding to the parasite\’s nerve and muscle cells, causing paralysis and death. This action disrupts the nervous system of the parasites, effectively treating infections. While primarily used for parasitic infections, research is ongoing regarding its potential in addressing other conditions.
Indications / Uses
Ivermectin is approved for treating several types of parasitic infections in humans, including:
- Strongyloidiasis: A condition caused by an intestinal roundworm.
- Onchocerciasis: Also known as river blindness, caused by the Onchocerca volvulus worm.
Off-label, ivermectin has been explored for conditions such as scabies and head lice, though professional consultation is advised before such use. Its potential use for other conditions should only be pursued under healthcare provider supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in tablet form for human use. Typical dosing is determined based on body weight and the type of infection being treated. Proper dosing is critical and should follow the advice of a healthcare professional. Factors like age, kidney or liver function, and other health conditions can influence dosing decisions. Pregnant or breastfeeding women should seek medical advice before use.
How to Take It Correctly Step-by-Step
