What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. It works by binding to specific sites in the parasites’ nerve and muscle cells, leading to paralysis and death of the parasites. This action helps eliminate the infection from the body. The medication is effective against a range of parasites but is not suitable for viral or bacterial infections.

Ivermectin is primarily approved for the treatment of several parasitic infections:
- Head Lice: Used as a topical treatment to eliminate lice infestations.
- Scabies: Used to treat mite infestations on the skin.

- Strongyloidiasis: Treats intestinal roundworm infections.
Off-label uses exist, but they should only be pursued under direct medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including:
- Oral Tablets: Commonly used for systemic infections. Dosage is based on body weight and specific condition.
