What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat infections caused by certain types of roundworms and ectoparasites. It works by binding to parts of the parasitic organism, resulting in increased permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. This mechanism of action makes it effective in treating diseases like onchocerciasis and strongyloidiasis.
Indications / Uses
Ivermectin is most commonly used to treat parasitic infections such as:
- Onchocerciasis: Also known as river blindness, this infection is caused by the worm Onchocerca volvulus.
- Strongyloidiasis: An infection by the roundworm Strongyloides stercoralis.
- Lice and Scabies: In certain cases, topical ivermectin is used to treat head lice and scabies infections.
Off-label, it has been investigated for additional uses. Any such use should be under professional medical supervision, as evidence can be mixed or limited in support.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets and topical creams. The dosing depends on several factors:
- The specific condition being treated.
- The patient\’s weight, as dosing is often weight-based.
- Other medical conditions, such as liver or kidney impairments, as they may require dosage adjustments.
As with any medication, users must follow their healthcare provider\’s instructions regarding dosing carefully.
How to Take It Correctly Step-by-Step
