Ivermectin Dosage for Humans: A Complete Guide

Ivermectin is a widely used medication known for its effectiveness in treating various parasitic infections in humans. Originally developed as a veterinary drug, it has gained approval for human use to treat conditions such as scabies, head lice, intestinal strongyloidiasis, and onchocerciasis (river blindness). Understanding the correct ivermectin dosage for humans is essential to ensure effective treatment and avoid potential side effects.

What is Ivermectin?

Ivermectin belongs to the class of medications called anthelmintics. It works by paralyzing and killing parasites, disrupting their nervous system, and preventing them from reproducing. In addition to treating parasitic infections, ivermectin has shown promise in managing certain viral and inflammatory conditions.

Ivermectin Dosage Guidelines for Humans

The dosage of ivermectin for humans depends on the specific condition being treated, the patient’s weight, and overall health. Below are the general dosage recommendations based on different medical uses:

• Intestinal Strongyloidiasis – The recommended dosage is 200 mcg per kg of body weight, taken as a single dose on an empty stomach with water.

• Onchocerciasis (River Blindness) – The typical dosage is 150 mcg per kg of body weight, taken as a single dose. Follow-up doses may be needed every 3 to 12 months based on the severity of the infection.

• Scabies – The recommended dose is 200 mcg per kg of body weight, usually repeated after 7 to 14 days.

• Head Lice – A single dose of 200 mcg per kg may be taken, with a second dose recommended after 7 days if the infestation persists.

• Rosacea – Topical ivermectin (1% cream) is typically applied once daily to affected areas until the condition improves.

How to Calculate the Correct Ivermectin Dosage

To calculate the right ivermectin dosage, use the following formula:

$$\text{Dosage}=\text{Body weight (kg)}\times \text{Dosage recommendation (mcg/kg)}$$

For example, for a person weighing 70 kg being treated for scabies:

$$70\times 200=14,000\text{mcg}=14\text{mg}$$

Administration Instructions
