Albendazole 400 mg is a widely used antiparasitic medicine prescribed for the treatment of various worm and parasitic infections in humans. It works by stopping the parasites from absorbing glucose, which leads to their death and removal from the body. Albendazole 400 mg is effective against intestinal worms such as roundworms , hookworms, whipworms, and pinworms, which are common in areas with poor sanitation. It is also used to treat tapeworm infections, including hydatid disease and neurocysticercosis, a serious infection of the brain caused by pork tapeworm larvae. In addition to intestinal infections, albendazole may be prescribed for tissue паразitic infections affecting the liver, lungs, or other organs. The medicine is often recommended in public health programs for deworming, especially in children, to improve nutrition, growth, and overall health. Albendazole is usually taken by mouth and may be advised with food to improve absorption, depending on the condition being treated. While generally well tolerated, albendazole should be used only under medical supervision, as treatment duration and suitability depend on the type of infection and the patient’s health status. Pregnant women and individuals with liver problems should consult a doctor before use.
