What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to a class of drugs called anthelmintics. It works by interfering with the nerve and muscle functions of parasites, leading to their paralysis and death. This action helps to eliminate the parasites from the infected individual.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections such as:
- Onchocerciasis (river blindness)
- Strongyloidiasis
- Head lice and scabies (topical forms)
There have been off-label discussions regarding ivermectin\’s antiviral properties, but these uses are not widely recommended without professional medical guidance as evidence is limited and requires more research.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms, including oral tablets, topical creams, and injectables. The oral form is most commonly used for parasitic infections in humans. Dosing is typically based on weight, medical condition, and response to therapy. Specific populations, such as those with liver conditions, may require adjusted dosing.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach, at least 1 hour before or 2 hours after a meal.
- Swallow the tablet whole with water.
- If a dose is missed, take it as soon as you remember, unless it is close to your next scheduled dose—never double up doses.
- Store in a cool, dry place away from direct sunlight.
Avoid using alcohol while taking ivermectin as it may increase certain side effects.
