What It Is and How It Works
Ivermectin is an antiparasitic medication that falls under the category of avermectins. It works by binding to certain chloride ion channels in the nerve and muscle cells of the parasites, leading to increased permeability and neurological paralysis, which eventually results in the death of the parasite.
Indications / Uses
The primary approved uses for ivermectin tablets include the treatment of parasitic infections like onchocerciasis (river blindness) and strongyloidiasis. It is sometimes used off-label for other parasitic infections if guided by a healthcare professional. Due to its anti-infective properties, it helps in reducing the parasitic burden, thus improving patient outcomes.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in tablet form. The dose typically depends on the patient’s weight and the specific condition being treated. Special considerations are necessary for individuals with liver conditions, as the drug is metabolized by the liver. Patients should follow their prescription label and consult their clinician for precise dosing guidance.
How to Take It Correctly Step-by-Step
Take ivermectin tablets with water on an empty stomach, approximately one hour before a meal. If you miss a dose, take it as soon as you remember unless it\’s almost time for your next dose. Avoid taking a double dose. Store tablets in a cool, dry place, away from direct sunlight.
