Mebendazole 100 mg is an antiparasitic medication commonly used to treat intestinal worm infections in humans. It works by preventing worms from absorbing glucose, which leads to their loss of energy and eventual death. This medicine is effective against several common parasitic infections, including roundworm, hookworm, whipworm and pinworm. These infections are especially common in areas with poor sanitation and can affect both children and adults. Mebendazole 100 mg is usually taken orally, with or without food, and the dosage depends on the type of worm infection being treated. For some infections, a single dose may be sufficient, while others require treatment over several days. In certain cases, repeat treatment may be recommended to prevent reinfection. The medication is generally well tolerated, with mild side effects such as stomach pain, diarrhea, or nausea occurring occasionally.By eliminating intestinal worms, mebendazole helps relieve symptoms like abdominal discomfort, diarrhea, weight loss, anemia, and poor nutrient absorption. It also plays an important role in improving overall health, growth, and nutritional status, particularly in children. Mebendazole should be used as directed by a healthcare professional, and good hygiene practices are essential to prevent reinfection and control the spread of parasitic worms.
