Albendazole is a broad-spectrum antiparasitic medication widely used to treat worm infections in humans. It belongs to the class of drugs known as benzimidazoles and works by inhibiting the growth and reproduction of parasitic worms. Albendazole 400 mg  is commonly prescribed for infections caused by intestinal worms such as roundworms, hookworms, pinworms, whipworms, and threadworms. It is also effective against tissue parasites like tapeworms (including neurocysticercosis caused by pork tapeworm larvae) and hydatid disease (caused by Echinococcus species).The medicine works by preventing the worms from absorbing glucose, which is essential for their survival. As a result, the worms lose energy, become immobilized, and eventually die, after which they are expelled naturally from the body through bowel movements. Albendazole is usually taken orally, often as a single dose, though some infections may require longer or repeated treatments depending on severity.It is considered safe and effective for both adults and children, but should always be taken under medical supervision. Albendazole helps relieve symptoms such as stomach pain, nausea, fatigue, and itching caused by worm infestations, and prevents complications like anemia or malnutrition. Maintaining good hygiene and sanitation practices alongside treatment helps prevent reinfection and supports overall recovery.
