Mebendazole 100 mg is an anthelmintic medication used to treat a variety of intestinal worm infections in humans. It is commonly prescribed for conditions caused by pinworms, roundworms, whipworms and hookworms. The Mebendazole 100 mg works by preventing the worms from absorbing glucose, which is essential for their survival. As a result, the parasites lose energy and eventually die, allowing the body to eliminate them naturally through the digestive system. Mebendazole is usually taken as a single dose or over a short course, depending on the type of infection. It is generally well tolerated, with mild side effects such as stomach pain, diarrhea, or nausea in some cases. Maintaining proper hygiene and sanitation is important alongside treatment to prevent reinfection. Always follow medical advice for dosage and duration.
