What It Is and How It Works
Ivermectin belongs to a class of medications called antiparasitic agents. It works by interacting with the invertebrate nervous system and muscle cells, increasing permeability to chloride ions which leads to paralysis and death of the parasite. This mechanism is highly effective against a range of internal and external parasites.
For human use, ivermectin is largely prescribed for treating infections caused by parasitic worms, lice, and mites. Its effectiveness is due to its capability to selectively target parasite nervous systems without significant impact on humans.
Indications / Uses
Ivermectin is primarily used for treating the following parasitic conditions in humans:
- Onchocerciasis (River Blindness): A condition caused by infection with Onchocerca volvulus, transmitted through blackfly bites.
- Lymphatic Filariasis: Caused by filarial worms transmitted through mosquito bites.
- Strongyloidiasis: An intestinal infection from the roundworm Strongyloides stercoralis.
- Scabies: A skin infestation by the mite Sarcoptes scabiei.
- Pediculosis (head lice): Though more commonly treated with topical agents, ivermectin is sometimes used orally.
Off-label use for COVID-19 treatment gained attention but remains controversial and is not universally endorsed by health authorities.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several dosage forms, with the tablet form being most common for humans. The formulation used depends on the condition being treated. Dosing is typically weight-based and calculated by a healthcare professional to ensure efficacy and minimize the risk of side effects.
Special populations such as those with liver or kidney impairments, pregnant or breastfeeding women, elderly individuals, and children require careful dosing considerations due to variations in metabolism and body composition.
How to Take It Correctly Step-by-Step
- Take ivermectin exactly as prescribed by your healthcare provider.
