What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used for treating certain worm infections. In humans, Ivermectin is particularly effective against parasites such as Onchocerca volvulus and Strongyloides stercoralis. It operates by binding to glutamate-gated chloride channels in parasites, causing an increase in the permeability of the cell membrane to chloride ions, resulting in the paralysis and death of the parasite.
Indications / Uses
Ivermectin is approved for the treatment of several parasitic infections:
- Strongyloidiasis of the intestinal tract, caused by the nematode Strongyloides stercoralis.
- Onchocerciasis (river blindness), caused by the nematode Onchocerca volvulus.
- Some off-label uses include scabies and head lice, but these uses should only be pursued under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in oral tablet form for human use. It is essential to follow the prescription label and directions from a healthcare provider strictly. Dosage may vary depending on factors such as age, weight, and the severity of infection. Special populations, such as those with liver conditions, may require dosage adjustments.
