What It Is and How It Works
Ivermectin belongs to a class of drugs called antiparasitics. It works by binding to certain proteins in parasites, resulting in increased permeability of their cell membranes. This leads to paralysis and death of the parasites, effectively eliminating them from the body. The mechanism primarily targets parasites residing in the intestines but can also impact other types found in different bodily tissues. While primarily known for treating parasitic infections like river blindness and intestinal strongyloidiasis, ongoing research explores its potential for other conditions.
Indications / Uses
Primarily, ivermectin is used to treat various parasitic infections. These include:
- Onchocerciasis (river blindness): Caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: Intestinal infection by Strongyloides stercoralis.
- Scabies: A skin infestation caused by Sarcoptes scabiei.
- Pediculosis (lice): Infestation by head lice.
Off-label uses have been explored for conditions like rosacea and others, but these should only be pursued under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including:
- Oral tablets for systemic infections.
- Topical creams and lotions for skin conditions like rosacea and lice.
Dosing varies based on the specific condition, weight, and clinical guidelines. It is crucial to adhere to the prescription label or consult with healthcare providers for personalized dosing. Dosing considerations must account for individual factors such as patient age, liver or kidney function, and concurrent medication use.
