What It Is and How It Works
Ivermectin is an antiparasitic drug that has shown effectiveness in treating a variety of parasitic infections. It works by binding to specific proteins in the parasites, leading to their paralysis and death. This mechanism disrupts the nerve and muscle functions of the parasite, preventing them from surviving in the host.
Indications / Uses
Ivermectin is primarily approved for treating several types of parasitic worm infections. It is effective against:
- Onchocerciasis: Commonly known as river blindness, caused by the parasitic worm Onchocerca volvulus.
- Strongyloidiasis: An infection caused by the intestinal parasite Strongyloides stercoralis.
- Other Parasitic Infections: May also be used to treat infections caused by external parasites such as head lice and scabies, although usage can vary based on guidelines and regional approvals.
Off-label uses should always be under professional oversight, as the evidence for efficacy and safety in these contexts may vary.
Dosage Forms and Typical Dosing Considerations
Ivermectin is typically available in oral tablet form for human use, while topical forms and other preparations are used in animals. The dosage of ivermectin is highly dependent on the type of infection being treated, the patient\’s weight, and other individual health factors such as liver function. For pediatric, elderly, pregnant, or breastfeeding patients, dosing should only be determined by a healthcare professional.
