Albendazole is a broad-spectrum antiparasitic medication widely used for the treatment of worm infections in humans. It works by inhibiting the parasite’s ability to absorb glucose, which leads to energy depletion and eventually causes the worm to die. Albendazole 400 mg is effective against a variety of intestinal and tissue-dwelling worms, making it an important medicine in both individual treatment and public health programs. Common conditions treated with albendazole include roundworm , hookworm infection, pinworm , whipworm , and threadworm . It is also used for more serious parasitic infections such as hydatid disease and neurocysticercosis, a brain infection caused by pork tapeworm larvae. Because of its wide coverage, albendazole is often recommended in areas where multiple worm infections are common. Albendazole is usually taken orally, either as a tablet or suspension, and is often advised to be taken with food to improve absorption, especially for tissue infections. Most people tolerate the medicine well, though mild side effects such as nausea, abdominal pain, headache, or dizziness may occur. In long-term or high-dose use, liver function monitoring may be required. Overall, albendazole plays a vital role in controlling worm infections, improving nutrition, reducing anemia, and enhancing overall health, particularly in children and populations living in endemic regions.
