What It Is and How It Works
Ivermectin is an antiparasitic agent derived from avermectins. It works by binding to invertebrate nerve and muscle cells, increasing permeability and leading to paralysis or death of the parasites. This mechanism is effective against a range of parasites including certain worms, lice, and mites.
Indications / Uses
Ivermectin is primarily prescribed for parasitic infections such as:
- Onchocerciasis: A condition caused by the Onchocerca volvulus worm, leading to severe itching and potential vision impairment.
- Strongyloidiasis: An infection of the intestines caused by the Strongyloides stercoralis worm.
- Scabies: A skin condition caused by mites.
- Others: Off-label uses may exist but should be supervised by healthcare professionals.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets typically ranging from 3 mg and topical formulations such as creams or lotions for skin conditions. The correct dosage is determined by factors like body weight, age, the specific condition being treated, and the patient’s overall health. Patients must strictly follow the instructions provided by their healthcare provider.
How to Take It Correctly Step-by-Step
- Follow the prescribed dosage on an empty stomach with water.
- Avoid taking it with other medications unless approved by a healthcare provider.
- Store tablets at room temperature away from moisture and heat.
