What It Is and How It Works
Ivermectin is an antiparasitic medication primarily used to treat infections caused by certain parasites. By binding to invertebrate muscle and nerve cells, it increases the permeability of cell membranes to chloride ions, leading to paralysis and death of the parasites. Although it is highly effective against numerous parasites, including roundworms and mites, its mechanism is targeted specifically to these organisms, minimizing effect on human hosts.
Indications / Uses
Ivermectin tablets are officially used to treat two primary parasitic infections in humans:
- Onchocerciasis (River Blindness): A tropical disease caused by Onchocerca volvulus.
- Strongyloidiasis: An intestinal infection caused by Strongyloides stercoralis.
There are additional off-label possibilities for ivermectin use in other parasitic infections; however, their application should only be determined by healthcare professionals.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in the form of oral tablets. Dosage varies significantly depending on factors such as the type of infection being treated, patient weight, and other health conditions. Typical dosing usually considers body weight and medical condition. It is crucial for patients to adhere strictly to prescribed doses or seek professional consultation for tailored dosing, particularly when dealing with renal or hepatic impairments.
How to Take It Correctly Step-by-Step
To maximize the effectiveness of ivermectin tablets and minimize side effects, follow these instructions carefully:
- Take ivermectin on an empty stomach with water, usually one hour before a meal.
- If a dose is missed, take it as soon as possible. Skip it if the next dose is due soon; never double doses.
