What It Is and How It Works
Ivermectin is an antiparasitic medication that has been used for decades. It belongs to a class of drugs known as avermectins, which work by binding to certain cell membrane channels in parasites, causing paralysis and death of the parasite. Its mechanism primarily involves increasing the permeability of the cell membrane to chloride ions, disrupting neural and muscular functions in the parasite.
Indications / Uses
Beyond its FDA-approved uses for treating conditions caused by parasitic worms, Ivermectin has also been used to treat head lice, scabies, and other parasitic infections. In some regions, off-label uses have been explored, but these should only be undertaken under professional supervision due to varying evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral Tablets: Common for treating intestinal and systemic infections.
- Topical Creams and Lotions: Often used for skin-based parasite infections like scabies.
- Injectable Forms: Primarily used in veterinary medicine, not typically for human use.
Dosing is often based on the condition being treated, weight, age, liver function, and whether the person is pregnant or breastfeeding. Patients need to follow the prescription and advice given by their healthcare provider precisely.
