What It Is and How It Works
Ivermectin is an antiparasitic medication belonging to the avermectin family of drugs. It works by binding to and activating glutamate-gated chloride ion channels in the parasites\‘ nerve and muscle cells. This leads to increased permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasite.
Indications / Uses
Primarily, ivermectin is used to treat infections caused by certain parasites. It is FDA-approved for the treatment of:
- Onchocerciasis (river blindness) caused by the worm Onchocerca volvulus.
- Strongyloidiasis of the intestinal tract caused by the worm Strongyloides stercoralis.
- Scabies and head lice in some regions, although approval may vary by country.
Additionally, ivermectin has been used off-label for other parasitic infections, but such uses should only be undertaken with healthcare provider guidance.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms, including oral tablets and topical formulations, tailored to the condition being treated. Common factors influencing dosing include:
- Age and weight of the patient.
- Specific parasitic infection being treated.
- Presence of liver or kidney impairment.
- Concurrent medications that may interact with ivermectin.
It is crucial to follow prescribed dosing instructions and consult with healthcare providers for individual advice.
