What It Is and How It Works
Ivermectin is an anti-parasitic medication that effectively targets various parasites. The drug works by binding to glutamate-gated chloride channels within the parasite\’s nerve and muscle cells. This binding action increases the permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. Its use primarily involves treatments for infections caused by roundworms, one of the most common parasitic worms.
Indications / Uses
Ivermectin is FDA-approved for treating:
- Strongyloidiasis: An infection caused by the parasitic worm Strongyloides stercoralis.
- Onchocerciasis (River Blindness): Caused by the parasite Onchocerca volvulus, transmitted through blackfly bites.
Off-label, it has been explored for treating head lice and certain viral infections, but these uses require careful evaluation by healthcare providers due to varying evidence and potential safety concerns.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form. Dosage is determined based on the specific condition being treated, as well as patient characteristics such as weight, age, kidney function, and presence of other concurrent health issues. Note that:
- Dosage for strongyloidiasis varies and is often given as a single dose.
- Dosing adjustments may be necessary for individuals with hepatic impairment.
- Patients must follow the prescription provided by their healthcare provider.
How to Take It Correctly Step-by-Step
- Take ivermectin on an empty stomach, at least 1 hour before or 2 hours after a meal, with a full glass of water.
- If a dose is missed, take it as soon as you remember unless it\’s almost time for the next dose. Do not double up doses.
