What It Is and How It Works
Ivermectin is an antiparasitic medication that works by binding to the muscle and nerve cells of parasites, leading to paralysis and death of the parasite. It is effective against a broad range of internal and external parasites. In technical terms, ivermectin acts on specific ion channels in the parasite\’s nerve and muscle cells, disrupting their normal function.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections such as:
- Strongyloidiasis: An intestinal infection caused by the Strongyloides stercoralis parasite.
- Onchocerciasis (river blindness): A tropical disease caused by the Onchocerca volvulus parasite.
- Scabies and lice: Ivermectin is sometimes used for more severe or resistant cases of these skin infestations.
While discussed in the context of COVID-19, there are insufficient studies to recommend ivermectin for its prevention or treatment. Its use for COVID-19 should only occur in a research setting or close supervision when regulated by public health authorities.
Dosage Forms and Typical Dosing Considerations
Ivermectin typically comes in several forms:
- Tablets: Commonly used for internal parasitic infections.
- Topical cream: Used for skin conditions such as rosacea.
Dosing varies with use and patient characteristics. It is important to follow dosing instructions carefully, as doses depend on body weight and the specific condition being treated. Take special caution in individuals with liver or kidney impairment, and seek a physician’s advice. Pregnant or breastfeeding women should consult their healthcare provider before taking ivermectin.
How to Take It Correctly Step-by-Step
Step 1: Always take ivermectin exactly as prescribed by your healthcare provider.
