What It Is and How It Works

Ivermectin is a broad-spectrum antiparasitic medication. It functions by binding to certain proteins in parasites, leading to increased permeability of the cell membranes. This process eventually results in the paralysis and death of the parasites. Its effectiveness spans a range of parasitic infections, making it a critical tool in global health.

On a technical level, ivermectin acts on the invertebrate-specific glutamate-gated chloride channels and also affects other ion channels of parasites, disrupting their nervous and muscle systems.

Indications / Uses

Ivermectin for humans is primarily used for the treatment of:

  • Onchocerciasis: Commonly known as river blindness, caused by the parasite Onchocerca volvulus.
  • Strongyloidiasis: An intestinal infection caused by the worm Strongyloides stercoralis.
  • Lice and Scabies: Although not the primary treatment, ivermectin can be used when traditional treatments fail.

Off-label uses have been explored, but it is important to rely on validated clinical data and consult with a healthcare provider before considering such applications.

Dosage Forms and Typical Dosing Considerations

Ivermectin is most commonly available in tablet form, with the 12 mg tablet being a standard option for certain conditions. Dosing principles involve taking into consideration the type and severity of infection, patient’s body weight, and medical history. Factors such as kidney function, liver function, and pregnancy status also influence dosing decisions.

It is vital to adhere to the prescribed dosing regimen provided by healthcare professionals and not to adjust doses independently.

How to Take It Correctly

  1. Take ivermectin with a full glass of water on an empty stomach, at least one hour before or two hours after a meal.

  3. Store ivermectin in a cool, dry place away from direct sunlight.
  4. Avoid alcohol as it can increase the sedative effects and potential liver strain.
  5. Do not share your medication with others, and complete the full course as prescribed.
