What It Is and How It Works

Ivermectin is an antiparasitic drug that is effective against certain types of worm infestations and skin conditions caused by parasites. It primarily works by binding to specific ion channels in parasites, causing paralysis and death, which allows the body\’s immune system to eliminate them.

Technically, ivermectin targets glutamate-gated chloride channels, which are more prevalent and unique in parasites, sparing human cells. This selectivity allows ivermectin to effectively kill parasites without significant harm to human hosts when used as prescribed.

Indications / Uses

Ivermectin is primarily approved for the treatment of parasitic infections. These include:

  • Onchocerciasis (river blindness): Caused by the parasitic worm Onchocerca volvulus, leading to skin irritation and potential blindness.
  • Strongyloidiasis: An infection with the parasitic nematode Strongyloides stercoralis, affecting the intestines.
  • Scabies: A skin condition caused by the Sarcoptes scabiei mite, which results in itching and rash.

Off-label use of ivermectin has been a subject of research; however, any non-approved uses should be discussed with a healthcare provider, as the safety and efficacy of such applications may not be established.

Dosage Forms and Typical Dosing Considerations

Ivermectin comes in several forms, each suitable for a specific indication:

  • Tablets: Commonly used for systemic infections like onchocerciasis and strongyloidiasis.
  • Topical formulations: Creams and lotions are typically used for skin conditions like scabies.

The dosing of ivermectin depends on factors such as the patient\’s weight, the specific condition being treated, and the individual\’s kidney and liver function. As with any medication, patients must follow their healthcare provider\’s guidance and prescribed label instructions for dosing.

  4. Do not double doses: If you miss a dose, take it as soon as you remember unless it is close to the next scheduled dose. Do not double up to make up for a missed dose.
  5. Avoid sharing the medication: Do not share your medication with others, even if they have similar symptoms.
  6. Storage: Store ivermectin in a cool, dry place away from direct heat and moisture.
