What It Is and How It Works
Ivermectin is a medication that treats a variety of parasitic infections by causing paralysis and death in parasites. It binds to certain chloride channels in the parasites’ nerve and muscle cells, leading to an influx of chloride ions that paralyze these cells. This mechanism effectively immobilizes and kills the parasites, helping to clear infections in humans.
Indications / Uses
Ivermectin is primarily approved for treating onchocerciasis (river blindness) and strongyloidiasis. It is also used for scabies and lice infestations. In recent times, there has been interest in its application against viral infections, including COVID-19, although such use is off-label and should only be done under professional supervision. Approvals and recommended uses can vary by country, and it\’s important to follow local guidelines.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available as oral tablets, typically used in human medicine, and topical creams or lotions for certain skin conditions. Veterinary ivermectin formulations exist, but these should not be used by humans. The dosing of ivermectin depends on the type of infection, body weight, and the individual\’s health status. It is crucial to adhere to the prescribed schedule as recommended by a healthcare provider, as incorrect dosing can be dangerous.
How to Take It Correctly Step-by-Step
To take ivermectin correctly:
- Follow the prescription strictly: Do not self-adjust dosing based on the package or information online.
- Take on an empty stomach, at least one hour before or two hours after a meal, unless otherwise directed by your physician.
- If you miss a dose, take it as soon as you remember unless it’s close to the time of your next dose; never double up doses.
- Store at room temperature, away from moisture and heat.
- Adhere to follow-up schedules to allow healthcare providers to monitor progress and side effects.

Drug, Food, and Supplement Interactions
Certain medications like warfarin and some anticonvulsants can interact with ivermectin, potentially altering its efficacy or increasing side effects.
