What It Is and How It Works
Ivermectin is an antiparasitic medication that targets and disrupts the nerve and muscle functions of parasites, leading to their paralysis and death. This action is primarily achieved by binding to glutamate-gated chloride ion channels within the parasites\’ nerves and muscles, causing an influx of chloride ions. This influx leads to hyperpolarization of the nerve cells, leading to paralysis, and subsequently, the death of the parasite.
Indications / Uses
Ivermectin is approved and commonly used to treat several parasitic infections, including:
- Onchocerciasis: Also known as river blindness, this is a tropical insect-borne disease caused by the parasite Onchocerca volvulus.
- Strongyloidiasis: A roundworm infection that can affect the stomach and intestines.
- Other uses: It has been used off-label for certain conditions, such as scabies and lice, but such uses should only be attempted under professional supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in various forms such as tablets and in liquid form. The choice of form depends on the indication, patient age, weight, and other health considerations. The liquid form is typically reserved for cases where swallowing pills is difficult. For any dosing, adherence to prescribing guidelines is critical and must account for factors such as:
- Patient\’s age and weight
- Severity and type of infection
- Kidney and liver function
- Potential drug interactions
It is crucial to follow label directions or healthcare provider instructions for dosing.
How to Take It Correctly Step-by-Step
When taking ivermectin, follow these general steps to ensure proper use:
- Take on an empty stomach, at least one hour before a meal.

- If you miss a dose, take it as soon as you remember unless it is almost time for the next dose.
- Store the liquid at room temperature away from moisture and heat.
Do not double-up on doses. Never change your dosage without first consulting with a healthcare professional.
