Quick Facts Scannable
- Ivermectin is used to treat parasitic infections, such as those caused by roundworms and certain mites.
- It works by paralyzing and killing parasites or stopping adult parasites from reproducing.
- Commonly available in tablets, topical forms, and injectables (for veterinary use only).
- Onset of action can vary, and effects for some conditions may be noticeable within a few days.
- Common side effects include dizziness, nausea, and mild skin irritation.

What It Is and How It Works
Ivermectin is an antiparasitic agent that can treat various infections caused by parasitic organisms. It belongs to a class of drugs known as anthelmintics. By binding tightly to glutamate-gated chloride ion channels within invertebrate nerve and muscle cells, ivermectin increases the permeability of the cell membrane to chloride ions. This, in turn, results in paralysis and death of the parasites.
Indications / Uses
Ivermectin is primarily approved for treating several parasitic infections, including:
- Intestinal strongyloidiasis (caused by the roundworm Strongyloides stercoralis)
- Onchocerciasis (river blindness)
- Other off-label uses may include treating scabies, lice, and as part of mass drug administration programs in certain regions for filariasis.
It\’s crucial for individuals who suspect a parasitic infection to seek professional diagnosis and discuss appropriate treatment options.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various dosage forms, including oral tablets and topical preparations. The dosing typically depends on the specific condition being treated, the patient\’s weight, and other health factors. For adults and children above a certain weight, the dose may be determined by a mg/kg calculation.
It\’s imperative that dosing adjustments for special populations, such as those with liver or kidney impairment, are made by a healthcare provider. Pregnant or breastfeeding women should also consult their doctor before taking ivermectin, as safety data is limited in these populations.
How to Take It Correctly Step-by-Step
