What It Is and How It Works

Ivermectin is a medication used to treat parasitic infections. It belongs to a class of medications called anthelmintics which work by paralyzing and killing parasites, ultimately preventing them from multiplying in the human or animal host. Ivermectin is effective against a broad spectrum of parasites including those causing river blindness, lymphatic filariasis, and scabies.

Indications / Uses

The primary approved uses of ivermectin include treatment of:

  • Onchocerciasis (river blindness): Common in parts of Africa and Latin America, caused by parasitic worms.
  • Strongyloidiasis: An intestinal worm infection.
  • Scabies: Particularly when resistant to topical treatments.

Off-label uses have been explored, particularly during the COVID-19 pandemic, but these require rigorous clinical oversight and are not universally endorsed due to unclear evidence of efficacy.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several formulations, including tablets, topical creams, and injectables. The specific form and dosing depend on the condition being treated, the patient\’s age, weight, and overall health.

  • Tablets: Typically used for systemic infections like onchocerciasis and strongyloidiasis. Dosing is based on body weight.
  • Topical formulations: Usually prescribed for conditions like head lice and rosacea.
  • Injectables: Primarily used in veterinary medicine.

Pediatric dosing and considerations for individuals with liver or kidney impairments should be handled by healthcare professionals.

How to Take It Correctly Step-by-Step

  • Timing and Administration: Take ivermectin on an empty stomach with a full glass of water.
  • Missed Dose: If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose.
  • Storage: Store at room temperature away from moisture and heat.
