Albendazole is an antiparasitic medication commonly used in humans to treat a wide range of worm infections. It works by preventing parasites from absorbing glucose, which leads to their gradual death and elimination from the body. Albendazole 400 mg is effective against intestinal worms such as roundworms, hookworms, pinworms, and whipworms. It is also used for more serious infections like hydatid disease and neurocysticercosis, a condition where tapeworm cysts affect the brain.

Albendazole is generally well tolerated, but some people may experience side effects such as nausea, abdominal pain, dizziness, headache, or temporary hair loss with long-term use. In rare cases, liver function changes or blood-related effects may occur, so monitoring is advised during prolonged therapy. Albendazole should be used under medical supervision, especially in pregnant women or patients with liver disease, to ensure safe and effective treatment.
