Mebendazole 100 mg is an antiparasitic medicine commonly used in humans to treat intestinal worm infections. It is effective against conditions such as pinworm , roundworm, whipworm, and hookworm infestations. The Mebendazole 100 mg works by preventing the worms from absorbing glucose, which leads to their gradual death and removal from the body through the digestive system. Mebendazole is usually taken as a single dose or short course, depending on the type of infection, and may be repeated after a few weeks to prevent reinfection. It is generally well tolerated, though mild side effects like stomach pain, diarrhea, or nausea may occur. Maintaining good hygiene, such as handwashing and cleaning bedding, is important during treatment to avoid spreading infection. Mebendazole is widely used due to its effectiveness, safety profile, and convenience in treating common parasitic infections in both adults and children.
