Understanding Ivermectin for Human Use
Ivermectin is a prescription medication widely used to treat various parasitic infections in humans. Originally developed for veterinary use, it was later approved for human treatment due to its effectiveness and safety when used correctly.
In this article, we’ll cover everything you need to know about ivermectin dosage for humans, including how it’s calculated, common uses, and important safety tips.
What Is Ivermectin Used For?
Ivermectin is commonly prescribed for the following conditions in humans:
-
Strongyloidiasis (intestinal roundworm)
-
Onchocerciasis (river blindness)
-
Scabies
-
Head lice
-
Other parasitic infections
In some cases, ivermectin has been discussed for off-label use, but these should only be considered under strict medical supervision.
Ivermectin Dosage for Humans: General Guidelines
The correct ivermectin dosage depends on several factors, including your body weight, age, and the specific condition being treated. Always follow your healthcare provider’s instructions, as improper use can lead to serious side effects.
📌 Standard Dosage (Adults & Children over 15 kg):
-
Strongyloidiasis:
👉 200 mcg per kg of body weight, taken as a single dose.
A repeat dose may be necessary after 2 weeks. -
Onchocerciasis (River Blindness):
👉 150 mcg per kg, given every 6 to 12 months depending on severity. -
Scabies:
👉 200 mcg per kg, repeated after 7 to 14 days. -
Lice:
👉 A similar dose of 200 mcg per kg, often repeated after one week.
Example Calculation: For a person weighing 70 kg (154 lbs), the dosage would typically be:
70 kg x 200 mcg = 14,000 mcg (or 14 mg).
