What It Is and How It Works
Ivermectin is an antiparasitic medication derived from avermectins, a group of compounds discovered in the 1970s. It works by binding to parts of the parasite\’s nervous system, causing paralysis and death of the parasite. In humans, it is specifically used to treat infections caused by certain parasites like river blindness (onchocerciasis) and certain types of intestinal worms (strongyloidiasis).
Indications / Uses
The primary approved uses for ivermectin include the treatment of river blindness and intestinal strongyloidiasis. It is also used to treat head lice and scabies, depending on the region\’s health regulations. While there have been discussions about its possible use in viral infections, such use should be considered experimental and guided by current clinical research findings.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms for human use:
- Tablets: Typically prescribed in specific weight-based doses for parasitic infections.
- Topical Creams/Lotions: Used for conditions like head lice and rosacea.
Factors influencing dosing include the individual\’s weight, specific infection being treated, and the presence of any comorbid conditions. Pregnant and breastfeeding women, children, and those with liver or kidney issues may require adjusted dosing or monitoring.
How to Take It Correctly Step-by-Step
- Follow prescription instructions carefully, using the exact dosage recommended by your healthcare provider.
- Typically taken on an empty stomach with water to aid absorption.
- If a dose is missed, consult your healthcare provider for advice; do not double the next dose.
