Mebendazole (mebendazole) — Uses, Dosage, Side Effects & Safety

Drug class: Anthelmintic (Anti-parasitic)

Overview

Mebendazole is a medication used to treat infections caused by several types of intestinal worms, including pinworm, roundworm, whipworm, and hookworm. It works by preventing the worms from absorbing sugars they need to survive, which causes them to die and be eliminated from the body. This medicine is commonly prescribed for both adults and children and is available in tablet and chewable forms. Mebendazole is generally well-tolerated and is considered effective for single or mixed worm infections. It is important to take the medication exactly as directed and to complete the full course, even if symptoms improve. Patients should be aware that good hygiene practices, such as handwashing and cleaning household items, are essential to prevent reinfection and spread to others.
