What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat infections caused by certain parasites. It belongs to a class of drugs called anthelmintics, which target parasitic worms. Ivermectin works by binding to specific proteins present in the nerves and muscles of parasites, ultimately leading to their paralysis and death. This mechanism helps eliminate the parasites from the human body.
Indications / Uses
Ivermectin is primarily indicated for treating infections such as:
- Onchocerciasis: Also known as river blindness, primarily affecting the skin and eyes.
- Strongyloidiasis: A roundworm infection causing gastrointestinal symptoms.
- Scabies and Head Lice: While not officially approved in some regions, ivermectin is frequently used for severe or resistant cases.
Off-label uses, such as for certain viral infections, should always be supervised by a healthcare professional, as current evidence and guidelines vary.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several dosage forms, including oral tablets and topical lotions. The dosing of ivermectin varies based on the infection being treated, and factors such as body weight, kidney, and liver function can influence the appropriate dose.
