What It Is and How It Works
Ivermectin is an antiparasitic agent used in various medical scenarios. It primarily works by binding to glutamate-gated chloride channels in the nerve and muscle cells of invertebrates. This action leads to an influx of chloride ions, resulting in paralysis and death of the parasite. Clinically, this mechanism is leveraged to eliminate parasitic worms and treat infections like river blindness (onchocerciasis) and threadworm (strongyloidiasis).
Indications / Uses
In humans, ivermectin is primarily used for the treatment of:
- River blindness (onchocerciasis): Affects the skin and eyes, caused by the parasite Onchocerca volvulus.
- Threadworm infection (strongyloidiasis): Caused by the nematode Strongyloides stercoralis.
Off-label uses should be under strict medical supervision as the evidence varies and requires careful consideration.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in oral tablet form for human use and topical formulations intended to address skin conditions. Dosage is not one-size-fits-all; it depends on factors like the type of infection being treated, the patient’s weight, age, liver function, and any coexisting health conditions. Therefore, prescribing information supplied by healthcare professionals is crucial, and patients should follow it strictly.
How to Take It Correctly Step-by-Step
- Take the oral tablet with a full glass of water to ensure proper absorption.
- If prescribed, take the medicine on an empty stomach, usually 1 hour before or 2 hours after a meal.
- Adhere strictly to the dosing schedule provided by your healthcare provider.
- Store the medication at room temperature, away from moisture and heat.
