What It Is and How It Works
Ivermectin belongs to a group of medications known as antiparasitics. It works by binding to specific chloride ion channels in the nerve and muscle cells of parasites, which increases the permeability of the cell membrane. This action causes paralysis and ultimately kills the parasite. Its effectiveness depends on attacking the neural transmission of parasites, ensuring they cannot survive within the host.
Indications / Uses
Primarily, ivermectin is used to treat various parasitic infections in humans, including:
- Onchocerciasis (River Blindness): A parasitic disease caused by the worm Onchocerca volvulus, transmitted by blackflies.
- Strongyloidiasis: An infection with the roundworm Strongyloides stercoralis.
- Lice and Scabies: Though not its primary indication, ivermectin is sometimes used to treat head lice and skin mites when other treatments have failed.
Off-label uses exist but should only be pursued under clear medical guidance due to the potential risks involved.
Dosage Forms and Typical Dosing Considerations
Ivermectin is primarily available in oral tablet form when prescribed for humans, usually in strengths of 3 mg. The dosing is largely based on body weight and the condition being treated. It\’s crucial that only a healthcare provider determines the appropriate dose. For certain conditions, ivermectin may be prescribed off-label in different forms or strengths.
Factors such as liver function, age, and concurrent medications may influence dosing. For individuals with liver disease, dose adjustments may be necessary. Pregnant or breastfeeding women should only take ivermectin when absolutely necessary and under medical supervision.
How to Take It Correctly Step-by-Step
- Timing: Take ivermectin on an empty stomach with water, as food may affect absorption.
- Missed Dose: If a dose is missed, take it as soon as you remember unless it\’s close to the time for your next dose. Do not double doses.
- Storage: Store at room temperature away from light and moisture. Always keep medication out of reach of children.
