Quick Facts
- Ivermectin is used to treat parasitic infections such as river blindness and intestinal strongyloidiasis.
- It works by binding to specific channels in the parasites, leading to their paralysis and eventual death.
- Common forms include oral tablets and topical formulations.
- Onset of action can vary depending on the condition being treated.
- Common side effects may include dizziness, nausea, and diarrhea.
- Potential interactions with other medications can occur, highlighting the need to consult with healthcare providers.

What It Is and How It Works
Ivermectin belongs to a class of drugs called antiparasitic agents. It functions by binding to glutamate-gated chloride channels in the nerve and muscle cells of parasites. This action increases the permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite. This mechanism is effective against a variety of parasitic infections, providing both symptom relief and addressing the underlying infection.
Indications / Uses
Ivermectin is primarily used to treat parasitic infections such as onchocerciasis (river blindness) and intestinal strongyloidiasis in humans. It is also used off-label in the treatment of scabies and lice. However, these uses should only be undertaken under the guidance of a healthcare professional, as unapproved uses can carry risks.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form and topical formulations. The dosing of ivermectin is generally determined based on the weight of the patient, the specific condition being treated, and other individual factors such as liver function and co-existing health conditions. Dosing adjustments are often necessary for populations with potential vulnerabilities such as pediatric or geriatric patients. It is crucial to follow clinician and pharmacist guidance for the correct dosing regimen.
How to Take It Correctly Step-by-Step
When taking oral ivermectin, it is typically advised to do so on an empty stomach with water. Missing a dose should be addressed by consulting a healthcare provider for guidance rather than doubling up on the next dose. Ivermectin should be stored at room temperature and kept away from excessive moisture and heat. Avoid consuming alcohol with this medication as it may interfere with its efficacy and increase the risk of adverse reactions.
