Quick Facts

  • Commonly used for managing parasitic infections such as river blindness and head lice.
  • Available in oral, topical, and injectable forms.

What It Is and How It Works

Ivermectin belongs to a class of medications called antiparasitic agents. It works by binding to certain chloride channels in the nerve and muscle cells of parasites, leading to an increased permeability of the cell membrane and causing paralysis and death of the parasites. This mechanism makes it effective in treating infections caused by worms, lice, and mites.

Indications / Uses

Ivermectin is primarily approved for treating parasitic infections such as:

  • Onchocerciasis (river blindness)
  • Strongyloidiasis (intestinal infection caused by a type of roundworm)
  • Scabies
  • Head lice

It is important to note that any off-label use of ivermectin should be discussed with and supervised by a healthcare provider.

Dosage Forms and Typical Dosing Considerations

Ivermectin is available in several formulations, including oral tablets, topical creams, and lotions. The dosage and form depend on the specific condition being treated. Factors influencing dosing include the patient\’s age, weight, liver and kidney function, and other medical conditions. For instance:

  • For oral formulations, doses are generally based on body weight.
  • For topical use, the application is often determined by the extent of the skin condition.

Readers should follow the prescription label and clinician/pharmacist instructions closely.

How to Take It Correctly Step-by-Step

  • Oral ivermectin is often taken on an empty stomach with water.
  • A missed dose should be taken as soon as remembered unless it\’s near the time of the next dose—do not double doses.
  • Medications should be stored as per packaging instructions, typically at room temperature, away from moisture and heat.
