What It Is and How It Works
Ivermectin is an antiparasitic medication that works by affecting the nerves and muscles of parasitic worms, leading to their paralysis and eventual death. For more technical understanding, ivermectin binds to specific ion channels in the muscle and nerve cells of parasites, increasing permeability, causing an influx of chloride ions, leading to hyperpolarization, paralysis, and death of the parasites.
Indications / Uses
Ivermectin is primarily prescribed for treating parasitic infections such as strongyloidiasis (a type of intestinal worm infection) and onchocerciasis (river blindness). It is effective in treating other off-label conditions, but such use should only occur under the guidance of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Ivermectin is most commonly available in tablet form, though other forms exist for veterinary or less common human uses. The dosage is determined based on body weight, condition being treated, and response to treatment. Typically, dosing considerations include factors such as the patient\’s age, liver function, and other underlying health conditions. It is important to adhere to the prescribed dose and follow the instructions of your healthcare provider.
How to Take It Correctly Step-by-Step
Ivermectin tablets should generally be taken on an empty stomach, about an hour before a meal. If you miss a dose, take it as soon as you remember unless it\’s almost time for the next dose. In such cases, skip the missed dose and resume your regular schedule. Do not double up doses to make up for the missed one. Store the medication at room temperature, away from light and moisture.
