Quick Facts
- Primarily used for treating parasitic infections such as river blindness (onchocerciasis) and intestinal strongyloidiasis.
- Works by causing paralysis and death to parasitic worms.
- Common forms include tablets for human use and topical formulations for animals.
- Avoid use in children weighing less than 15 kg and pregnancy unless prescribed by a healthcare professional.

- Seek urgent help if you experience severe allergic reactions, such as difficulty breathing or swollen lymph nodes.
What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used for eliminating a broad range of parasites. It works by binding to certain chloride channels within the parasites, leading to increased permeability of their cell membranes, which ultimately results in their paralysis and death. While it effectively targets parasites like those causing river blindness and intestinal worms, its purported efficacy against viruses, such as the SARS-CoV-2 virus (which causes COVID-19), requires more rigorous scientific validation.
Indications / Uses
Ivermectin is FDA-approved for treating specific parasitic infections, including:
- Onchocerciasis (river blindness)
- Intestinal strongyloidiasis
- Other off-label uses might include scabies and resistant lice infections, but these should only be pursued under strict medical supervision.
Claims regarding its use in treating COVID-19 are primarily based on laboratory studies and have not been conclusively supported by large-scale clinical trials in humans.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets for human use and as topical formulations for veterinary use. Dosage commonly depends on factors like body weight, the specific condition being treated, and the patient\’s overall health status.
Generally, dosing requires consideration of kidney and liver function, as impaired organ function may necessitate dose adjustments. Use during pregnancy or lactation should be undertaken cautiously and always under healthcare provider advice.
How to Take It Correctly Step-by-Step
Here is a general guide for safely taking ivermectin:
- Follow prescriber\’s instructions carefully. Do not exceed the prescribed dose.
