What It Is and How It Works
Ivermectin is an antiparasitic medication that acts by binding to channels in the nervous system of parasites, disrupting their normal function. This leads to paralysis and elimination of the parasites from the body. For humans, specifically, it is effective against multiple parasites, including head lice, scabies, river blindness (onchocerciasis), and others.
Indications / Uses
Ivermectin is primarily used to treat a range of parasitic infections:
- Onchocerciasis: Commonly known as river blindness, caused by parasitic worms.
- Strongyloidiasis: An intestinal infection caused by roundworm.
- Head Lice: Used as a topical treatment for lice infestations.
- Scabies: A skin infestation with the mite Sarcoptes scabiei.
- Other Off-label Uses: Some healthcare providers may use ivermectin off-label in specific cases, but such use should always be under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral Tablets: Commonly prescribed for internal parasitic infections.
- Topical Creams/Lotions: Used for conditions like head lice and rosacea.
- Injectable Forms: Primarily used in veterinary medicine.
The dosing of ivermectin varies based on the condition being treated, the route of administration, and patient-specific factors such as age, weight, and medical history. It is crucial to follow a healthcare provider\’s guidance on dosing and administration.
