What It Is and How It Works
Ivermectin is an antiparasitic medication initially used to treat infections caused by certain parasites. It primarily works by paralyzing and ultimately killing the parasites. The drug binds to glutamate-gated chloride channels in the nerve and muscle cells of invertebrates, which leads to increased permeability and paralysis.
Indications / Uses
Ivermectin is FDA-approved to treat several parasitic infections, including:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal infection)
- Scabies and lice infestations
- Some veterinary uses for animals
Off-label uses are reported, but they should only be considered under a physician\’s guidance due to the variability in clinical evidence supporting such uses.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in tablet form. Dosing varies based on the infection being treated and patient-specific factors such as weight. For humans, it often involves a single oral dose or series of doses. For specific applications in veterinary medicine, other formulations are available.
Individual dosing considerations include factors such as age, liver function, other medications, and overall health status. Pregnant and breastfeeding women, as well as children, must follow a specialist\’s advice, as dosing adjustments may be required.
How to Take It Correctly Step-by-Step
When taking ivermectin:
- Follow the prescription label and clinician instructions.
