What It Is and How It Works
Ivermectin is an anti-parasitic agent that works by binding to glutamate-gated chloride channels in nerve and muscle cells of parasites, which results in paralysis and death of the parasite. This mechanism is very selective for parasites and does not affect mammals in the same way.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections, including:
- Onchocerciasis: Mainly found in parts of Africa, this condition causes severe itching and can lead to blindness.
- Strongyloidiasis: Caused by a type of roundworm found in tropical and subtropical climates.
- Head Lice: Often treated with topical formulations.
There are off-label uses reported, but these should be considered cautiously and treated under the advice of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is generally available in tablets and topical formulations. The dose depends on the infection being treated and other factors like body weight, age, and kidney or liver functionality.
For instance, the typical dosing for onchocerciasis is a single oral dose that might need to be repeated. People with liver or kidney issues or those who are pregnant should discuss potential dosing changes with their healthcare provider.
