What It Is and How It Works

Ivermectin is an antiparasitic medication that is used to treat a variety of parasitic infections. It functions by binding to specific chloride ion channels in the nerve and muscle cells of parasites. This leads to an increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. It is important to note that ivermectin is not an antibiotic and works specifically against parasitic worms.

Indications / Uses

Ivermectin is primarily approved for the treatment of certain parasitic infections:

• Strongyloidiasis: This infection is caused by the roundworm Strongyloides stercoralis.
• Onchocerciasis (River blindness): Caused by the parasite Onchocerca volvulus, often transmitted by blackfly bites.
• Scabies: A skin infestation caused by the mite Sarcoptes scabiei.

While there has been interest in other potential applications of ivermectin, such as use in viral infections, these uses remain under investigation and are not universally approved.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several forms, including oral tablets and topical formulations. The dosage of ivermectin depends on the condition being treated, typically based on body weight and the type of infection.
