Quick Facts
- Used primarily for treating parasitic infections in humans and animals.
- Belongs to the class of medications known as antiparasitic agents.
- Commonly found in oral tablet and topical forms.

What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat a variety of parasitic infections including strongyloidiasis and onchocerciasis in humans. It works by binding to glutamate-gated chloride channels found in invertebrate muscle and nerve cells, which increases permeability and leads to paralysis and death of the parasites. This action mechanism effectively clears parasitic infections from the host body.
Indications / Uses
Ivermectin is primarily approved for treating specific types of parasitic infections such as:
- Strongyloidiasis: A roundworm infection that affects parts of the intestine.
- Onchocerciasis: Also known as river blindness, primarily seen in sub-Saharan Africa.
- Scabies: Skin mite infestations, particularly in cases resistant to topical treatments.
Off-label uses have been explored, but such use should only occur under the guidance of a healthcare professional due to limited evidence and regulatory approval in many cases.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in oral tablet form, with dosing generally based on weight, health condition, and specific parasitic infections being treated. It is also found in topical formulations for certain skin parasitic conditions.
- Oral Tablets: Typically used for systemic infections.
- Topical Creams: Applied for localized skin infections like head lice or rosacea.
Dosing adjustments may be necessary for individuals with liver impairments, for pregnant or breastfeeding women, and for different age groups, under the close supervision of a healthcare professional.
How to Take It Correctly Step-by-Step
