What It Is and How It Works
Ivermectin is an antiparasitic agent that functions by binding to specific proteins in the parasites, leading to paralysis and death of the invaders. This mechanism works effectively on both external and internal parasites, curbing their ability to multiply and cause further harm. While its primary indication is for infections like strongyloidiasis, its scope is occasionally broadened to off-label uses, contingent upon professional supervision.
Indications / Uses
Ivermectin is mainly prescribed for treating infections such as:
- Onchocerciasis (River Blindness): Caused by the worm Onchocerca volvulus and transmitted through black fly bites.
- Strongyloidiasis: A gastrointestinal infection resulting from the Strongyloides stercoralis worm.
There are investigational uses of ivermectin under the supervision of healthcare professionals, though these should not be generalized due to varying approval statuses in different regions.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form, with dosing primarily based on body weight and the specific infection being treated. While typical dosing recommendations exist, a healthcare provider will tailor doses based on factors such as age, weight, kidney function, and concurrent medications. It’s essential to adhere strictly to prescribed doses and frequencies.
How to Take It Correctly Step-by-Step
- Take ivermectin tablets on an empty stomach with water.
- Avoid eating for at least one hour before and two hours after taking the tablet.
- If a dose is missed, take it as soon as remembered unless it’s close to the next scheduled dose—do not double doses.
- Store the medication at room temperature, away from moisture and heat.
Avoid alcohol during treatment to minimize the risk of increased side effects.
