Quick Facts

  • Primarily used to treat parasitic infections such as strongyloidiasis and onchocerciasis.
  • Works by paralyzing and killing parasites.
  • Commonly available in tablets and topical formulations.
  • Usually taken on an empty stomach with water.
  • Possible side effects include dizziness, nausea, and rash.
  • Interactions with other medications, foods, or supplements should be carefully managed.
  • Special caution is advised for pregnant or breastfeeding women.
  • Urgent medical help should be sought if experiencing severe side effects like difficulty breathing or seizures.

What It Is and How It Works

Ivermectin is an antiparasitic agent that has broad-spectrum activity against various parasites. It is derived from avermectins, initially produced by the bacterium Streptomyces avermitilis. Ivermectin works by binding to and activating glutamate-gated chloride channels in the nerve and muscle cells of parasites, leading to their paralysis and death. This mechanism targets specific chloride channels found in invertebrates, minimizing effects on the host organism.

Indications / Uses

Ivermectin is officially approved for treating certain parasitic infections:

  • Strongyloidiasis: An intestinal infection caused by the parasite Strongyloides stercoralis.
  • Onchocerciasis: Also known as river blindness, this condition results from infection with the parasite Onchocerca volvulus.

While ivermectin has garnered attention for its potential off-label use in treating COVID-19, this is not widely recommended due to insufficient clinical evidence. Only a healthcare professional can make decisions regarding off-label use based on reliable sources and specific patient conditions.

Dosage Forms and Typical Dosing Considerations

Ivermectin is commonly available in the form of oral tablets. Dosage is typically determined based on the medical condition, weight, and response to treatment, among other factors. Additional considerations should include:

  • Age and weight, especially in pediatric or underweight individuals.
  • Possible kidney or liver impairments that may alter dosing.
  • Pregnancy and breastfeeding status.
  • Coexisting medical conditions and concurrent medications.

For these reasons, users are advised to follow prescriptions and seek advice from healthcare professionals.
