Quick Facts about Ivermectin
- Used primarily to treat parasitic infections, such as onchocerciasis and strongyloidiasis.
- Works by interfering with the nervous system of parasites, effectively paralyzing and killing them.
- Commonly available in tablet form, with typical dosing guided by the type of infection.

What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to a class of medications known as avermectins. It targets the nervous and muscle systems of parasites, enhancing the release of neurotransmitters such as gamma-aminobutyric acid (GABA), which leads to the paralysis and eventual death of the parasites. Ivermectin does not directly kill parasites but interferes with their ability to reproduce and maintain key physiological functions, resulting in their elimination from the body.
Indications / Uses
Ivermectin is primarily used to treat infections caused by a variety of parasites, including:
- Onchocerciasis (River Blindness): Caused by the parasitic worm Onchocerca volvulus. Ivermectin helps to reduce skin itchiness and prevent the progression of blindness.
- Strongyloidiasis: An intestinal infection caused by Strongyloides stercoralis. Effective in eliminating adult parasites.
- Lice and Scabies: Sometimes used off-label when topical treatments fail.
Off-label uses are determined based on new scientific data and clinical guidelines but should only be undertaken with healthcare guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including tablets, creams, and lotions. The 12mg tablet is commonly used for systemic infections. Key factors influencing dosing include:
- Body Weight: Dosage is often calculated based on the patient\’s weight.
- Type of Infection: Different infections may require varying doses.
- Overall Health: Conditions like liver or kidney disease may necessitate dosage adjustments.
- Age: Dosing might differ in pediatric vs. adult populations.
It\’s crucial to adhere to the dosing guidelines provided by a healthcare professional and not to self-adjust doses.

To ensure ivermectin is effective, follow these steps:
- Take ivermectin on an empty stomach, with a full glass of water, at least one hour before or two hours after a meal.
