What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. In humans, it is primarily used to treat various parasitic infections, including onchocerciasis (river blindness), strongyloidiasis, and certain other worm infections.
The drug works by binding to specific channels in the parasite cell membranes, increasing the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. This effectively reduces the burden of the parasite in the infected individual.
Indications / Uses
Ivermectin is FDA-approved for treating:
- Onchocerciasis (river blindness)
- Strongyloidiasis of the intestinal tract
- Other health conditions caused by roundworms, as directed by a healthcare provider
Off-label, ivermectin has been used for certain cases of head lice, scabies, and rosacea. Such uses should only be pursued under medical guidance due to varying levels of evidence and potential risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Tablets
- Topical creams and lotions
The appropriate dosage is based on the specific condition being treated and factors like body weight and other health concerns. Generally, it is crucial to adhere strictly to the prescribed dosing schedule and consult a healthcare provider for any adjustments needed due to conditions like liver or kidney impairment, pregnancy, or breastfeeding.
How to Take It Correctly Step-by-Step
- Take ivermectin tablets by mouth with a full glass of water.
- It is often taken on an empty stomach, at least 1 hour before or 2 hours after a meal, unless directed otherwise by your healthcare provider.
- If a dose is missed, take it as soon as remembered, but if it’s near the time of the next dose, skip the missed dose to prevent doubling up.
- Store ivermectin at room temperature away from light and moisture. Do not store in the bathroom.
Avoid mistakes such as consuming alcohol simultaneously, as this can increase the risk of side effects. Do not share the medication with others, even if they have similar symptoms.
