What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat infections caused by certain parasites. It works by binding to parts of the parasite’s nerve and muscle cells, causing paralysis and eventually death. This action does not affect human nerve cells as significantly due to differences in cell structure, making it safer for human use when taken as prescribed.
Indications / Uses
Ivermectin is FDA-approved for treating specific parasitic infections. These include:
- Onchocerciasis (river blindness): Affects skin and eyes.
- Strongyloidiasis: Affects the intestines.
It may also be used off-label in treating other conditions such as scabies and head lice, but these uses require careful medical oversight and are not universally endorsed.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including:
- Tablets
- Topical creams
- Oral liquid
The dose of ivermectin prescribed varies based on weight, age, the condition being treated, and overall health. For most parasitic infections, a single dose is often sufficient, but factors like liver function, concomitant medications, and specific medical conditions can affect dosing. Always follow the prescription provided by your healthcare provider.
How to Take It Correctly Step-by-Step
For those prescribed ivermectin tablets:
- Take on an empty stomach, at least 1 hour before or 2 hours after eating.
- Swallow tablets with a full glass of water.
