Quick Facts
- Ivermectin is primarily used to treat parasitic infections such as river blindness, strongyloidiasis, and certain other worm infections.
- It works by paralyzing and killing parasites.
- Common forms include oral tablets and topical creams or lotions.

What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the avermectin class of drugs. Its mechanism of action involves binding to specific ion channels in the nerve and muscle cells of parasites, causing increased permeability. This leads to paralysis and death of the parasites, effectively treating the infection.
In some cases, ivermectin has been studied for off-label uses; however, these applications should be pursued only under medical supervision due to varying evidence regarding their effectiveness and safety.
Indications / Uses
Ivermectin is officially approved for the treatment of several parasitic infections, including:
- Onchocerciasis (river blindness): Caused by the parasite Onchocerca volvulus, leading to skin symptoms and eye disease.
- Strongyloidiasis: An infection with the intestinal roundworm Strongyloides stercoralis.
- Other infections: Includes certain forms of scabies and lice when topical treatments are less effective.
Its use beyond these indications, such as for viral infections, remains controversial and unsupported by conclusive clinical evidence.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several dosage forms:
- Oral tablets: Typically used for systemic parasitic infections.
- Topical formulations: Creams and lotions used for skin-related infections such as scabies and lice.
Dosing is influenced by various factors, including the specific infection being treated, patient weight, liver function, and other health considerations. It is essential to adhere to a healthcare provider’s prescription, as incorrect dosing may lead to ineffective treatment or increased risk of side effects.
How to Take It Correctly Step-by-Step
For the best results and to minimize risks, follow these general guidelines, but always adhere to your healthcare provider’s specific instructions:
- Take oral tablets on an empty stomach, at least 1 hour before or 2 hours after a meal, with a full glass of water.
- If a dose is missed, take it as soon as possible. Skip it if it’s near the time for the next dose.
- Do not take double doses to make up for a missed dose.
- Store ivermectin at room temperature away from excess heat and moisture.
