Quick Facts

  • Ivermectin is primarily used to treat parasitic infections such as river blindness (onchocerciasis) and lymphatic filariasis.
  • It works by paralyzing and killing parasites, effectively eliminating the infection.
  • Commonly available in tablet form for human use.
  • Potential side effects include dizziness, nausea, and diarrhea.
  • Ivermectin interactions can occur with medications like blood thinners and certain seizure medications.

What It Is and How It Works

Ivermectin is an antiparasitic medication belonging to the class of drugs known as avermectins. It works by binding to the chloride ion channels in the nerve and muscle cells of parasites. This binding increases membrane permeability to chloride ions, leading to paralysis and death of the parasite, thereby resolving the infection.

Originally derived from a naturally occurring bacterium found in soil, ivermectin\’s breakthrough use in controlling parasitic infections in livestock and pets expanded to its application in humans, showcasing its effectiveness and versatility.

Indications / Uses

The primary approved uses of ivermectin are for the treatment of certain parasitic infections such as:

  • River blindness (Onchocerciasis): Caused by the parasite Onchocerca volvulus.
  • Lymphatic filariasis: A tropical disease caused by thread-like parasitic worms.
  • Strongyloidiasis: An infection caused by the roundworm Strongyloides stercoralis.

While there has been interest in its use for other conditions, including as a treatment for viral infections, such uses are off-label and should only be explored under strict medical supervision and guidance.

Dosage Forms and Typical Dosing Considerations

Ivermectin is commonly available in tablet form for oral administration. The dosage is typically determined based on the patient’s body weight and the specific condition being treated. General dosing considerations include:

  • For river blindness and strongyloidiasis: A single dose based on the patient’s body weight.
  • Dosage adjustments may be necessary for individuals with liver or kidney impairments.
  • Pregnant or breastfeeding women should consult with healthcare providers to discuss potential risks and benefits.

Always adhere to the prescribed dosing schedule provided by a healthcare professional and do not self-adjust the dose.

How to Take It Correctly Step-by-Step

  • Take ivermectin tablets with water on an empty stomach, preferably one hour before breakfast.
  • If a dose is missed, take it as soon as you remember, but skip it if it\’s almost time for the next scheduled dose.
  • Avoid taking double doses to make up for missed ones.
  • Store the medication at room temperature away from moisture and heat.
  • Keep the medication out of reach of children and pets.

Common mistakes include taking it with food, which might affect absorption, or adjusting doses without consulting a healthcare provider.
