Understanding Ivermectin Dosage for Humans

Ivermectin is a widely recognized medication used to treat various parasitic infections in humans, including onchocerciasis (river blindness), strongyloidiasis, and scabies. It has also been explored for off-label uses in recent years, including for viral infections like COVID-19. While its efficacy in such contexts is debated, proper dosage and safe administration are critical when using ivermectin.

1. What Is Ivermectin?

Ivermectin belongs to a class of drugs known as anthelmintics. It works by paralyzing and killing parasites or stopping their reproduction. Originally developed for veterinary use, it has been adapted for human medicine and is included on the World Health Organization’s List of Essential Medicines.

2. Common Uses of Ivermectin

Ivermectin is approved for treating:

• Onchocerciasis: Caused by the Onchocerca volvulus parasite, leading to severe itching and blindness if untreated.
• Strongyloidiasis: A parasitic intestinal infection.
• Scabies: A skin condition caused by microscopic mites.
• Lice and Other Parasitic Infections: As directed by a physician.

3. Standard Dosage of Ivermectin for Humans

Ivermectin dosage is based on body weight and the condition being treated. It is typically prescribed as an oral tablet.

A. General Guidelines

• Onchocerciasis: A single dose of 150 mcg per kilogram (mcg/kg) of body weight, repeated every 6-12 months.
• Strongyloidiasis: A single dose of 200 mcg/kg of body weight. A follow-up stool test is often required to confirm eradication.
• Scabies: A single dose of 200 mcg/kg, repeated after 7–14 days if necessary.
