What It Is and How It Works
Ivermectin is an antiparasitic medication that has been widely used to treat infections caused by various parasites such as worms, lice, and mites. It works by binding to glutamate-gated chloride channels in the parasites\’ nerve and muscle cells, increasing the permeability of cell membranes to chloride ions. This results in paralysis and death of the parasites. Ivermectin is effective for conditions like onchocerciasis (river blindness), strongyloidiasis, and scabies.
Indications / Uses
Ivermectin is mainly used to treat parasitic infections such as:
- Onchocerciasis: Affects people in regions where this parasite is endemic, leading to symptoms like skin itching and, if untreated, blindness.
- Strongyloidiasis: Caused by intestinal threadworms, primarily affecting people in tropical and subtropical areas.
- Scabies: An infestation of mites on the skin that causes intense itching and persistent rashes.
While it has been discussed for off-label use in various diseases, including COVID-19, these uses must be undertaken with medical guidance and are subject to ongoing research and regulatory evaluation.
Dosage Forms and Typical Dosing Considerations
Ivermectin is usually available in oral tablets and topical formulations. The dosing of ivermectin largely relies on factors including the specific condition being treated, the patient\’s weight, liver and kidney function, and whether the patient is pregnant or breastfeeding. For example, dosage for onchocerciasis or strongyloidiasis is typically based on body weight.
It is crucial to follow dosing instructions from a healthcare professional and adhere to prescribed guidelines outlined on the medication packaging. Modifications should not be made without consulting a healthcare provider.
How to Take It Correctly Step-by-Step
For oral medications:
- Take with water on an empty stomach, either 1 hour before or 2 hours after a meal.
- Adhere strictly to the dosing schedule provided by your healthcare provider.
- If a dose is missed, take it as soon as possible unless the next scheduled dose is near.
- Do not double doses if one is missed.
For topical applications, follow the instructions specific to the product for safe application, usually applied directly to the affected area of the skin.
Store ivermectin in a cool, dry place away from direct sunlight.

Drug, Food, and Supplement Interactions
Ivermectin can interact with several medications. For instance, it may have interactions with warfarin (a blood thinner), leading to increased bleeding risk, or other medications that affect liver enzymes. Alcohol can also exacerbate drowsiness associated with ivermectin.
