Albendazole is a broad-spectrum anti-parasitic medication commonly used to treat worm infections in humans. It is highly effective against a variety of intestinal and tissue-dwelling worms, including roundworms, hookworms, pinworms, whipworms, and tapeworms. Albendazole works by inhibiting the worms’ ability to absorb glucose, which leads to depletion of their energy stores, immobilization, and eventual death of the parasites.For intestinal worm infections, Albendazole 400 mg  is usually taken orally in a single dose or over a few days, depending on the type and severity of the infection. The medication is absorbed better when taken with fatty foods, which can enhance its effectiveness. Albendazole is also used in treating certain tissue infections caused by larval forms of worms, such as cysticercosis or hydatid disease, though longer courses and higher doses are required in such cases under medical supervision. Common side effects are generally mild and include nausea, abdominal pain, headache, or temporary dizziness. Rarely, it may cause liver function changes or allergic reactions, so medical supervision is recommended for prolonged treatment. Albendazole is contraindicated in pregnancy, especially in the first trimester, and should be used with caution in people with liver disease. Albendazole is a safe and effective treatment for various human worm infections when used according to medical guidelines.
