What It Is and How It Works
Ivermectin is an antiparasitic medication. The drug works by binding to glutamate-gated chloride channels found in invertebrate nerve and muscle cells. This binding results in increased permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasites.
Indications / Uses
Ivermectin is approved for several parasitic infections, including:
- Onchocerciasis (River Blindness): Caused by the worm Onchocerca volvulus, mainly in Africa.
- Strongyloidiasis: An intestinal infection caused by the worm Strongyloides stercoralis.
- Scabies: A skin condition caused by infesting mites.
- Lice infestations: Though off-label for this use in many areas, it may be prescribed for head lice.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral tablets: Typically used for systemic infections.
- Topical form: For conditions like scabies and lice.
- Injectable form: More common in veterinary practice.
Dosing depends on weight, the type of infection, and overall health, including liver and kidney function. It is crucial to follow healthcare provider instructions closely.
How to Take It Correctly Step-by-Step
- Take the tablet with water on an empty stomach, at least an hour before eating.
- Do not double the next dose if a dose is missed; take it as soon as you remember if it’s within 12 hours of the scheduled time.
- Store the medication at room temperature away from extreme heat or moisture.
