Albendazole 400 mg is a broad-spectrum antiparasitic medicine widely used in humans to treat infections caused by intestinal and tissue worms. It works by inhibiting the parasites' ability to absorb glucose, which leads to energy depletion and eventually causes the worms to die. Albendazole 400 mg (https://genericmedicine.store/product/albendazole-400-mg/) is commonly prescribed for intestinal worm infections such as roundworm , hookworm, pinworm , whipworm, and threadworm. It is also effective in treating more serious parasitic diseases like hydatid disease and neurocysticercosis, which is caused by pork tapeworm larvae affecting the brain. The 400 mg dose is often given as a single dose or as part of a short treatment course, depending on the type and severity of infection. Albendazole is usually taken with food, especially fatty meals, to improve absorption. In mass deworming programs, it is widely used to reduce worm burden in communities, particularly among children. Common side effects may include nausea, abdominal pain, headache, or dizziness, which are usually mild and temporary. In long-term or high-dose treatments, liver function and blood counts may be monitored. Albendazole should be used under medical supervision, especially during pregnancy or in patients with liver disease, to ensure safe and effective treatment.
