Quick Facts
- Used For: Treating parasitic infections such as onchocerciasis and lymphatic filariasis.
- Mechanism: Works by binding to specific chloride channels in the parasite nerve and muscle cells, causing paralysis and death of the parasite.
- Common Forms: Oral tablets and topical formulations.
- Common Side Effects: Dizziness, nausea, itching, mild skin rash.
- Serious Side Effects: Neurotoxicity at high doses, including severe skin reactions and potential liver damage.
- Interactions: May interact with blood thinners and certain antibiotics.
- Special Populations: Caution in pregnant or breastfeeding women, children under 15 kg, elderly patients, and individuals with liver disease.
- Urgent Help: Seek immediate medical care for serious side effects such as seizures or severe skin reactions.
What It Is and How It Works
Ivermectin is an antiparasitic medication used to treat various parasitic infections. It works by interfering with the nerve and muscle functions of the parasites. Specifically, it binds to glutamate-gated chloride channels, leading to an influx of chloride ions in the cells, resulting in paralysis and death of the parasite. Importantly, it is designed to work against certain types of parasites and not effective against viruses, which is a common misconception.
Indications / Uses
Ivermectin is primarily approved for the treatment of parasitic infections such as:
- Onchocerciasis: Also known as river blindness, this infection is caused by the parasite Onchocerca volvulus.
- Lymphatic Filariasis: A tropical disease caused by microscopic worms.
- Strongyloidiasis: An infection caused by a type of roundworm.
While some interest exists around its use for other infections, including potential antiviral effects, such uses should only be considered under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets and topical formulations. The appropriate form and dose depend on the specific condition being treated. Dosing can be influenced by factors such as:
- Age and Weight: Particularly important in pediatric dosing to avoid toxicity.
- Liver Function: Since ivermectin is metabolized in the liver, dose adjustments may be needed for individuals with liver impairment.
- Other Health Conditions: Co-existing conditions may affect dosing and use.
As with any medication, it is crucial to follow the prescription label and advice of a healthcare provider.
How to Take It Correctly Step-by-Step
Taking ivermectin correctly is critical to ensure safety and effectiveness. Here are general guidelines:

- If you miss a dose, take it as soon as you remember, unless it\’s almost time for the next dose. Do not double up doses.
- Avoid consuming alcohol while taking ivermectin as it may increase the risk of side effects.
- Store the medication at room temperature away from moisture and heat.
