Albendazole is a broad-spectrum anthelmintic medication commonly used to treat various worm infections in humans, including roundworms, hookworms, whipworms, and tapeworms. Albendazole 400 mg works by inhibiting the parasite’s ability to absorb glucose, which depletes its energy stores and ultimately kills the worm. Albendazole is effective for both intestinal and tissue-dwelling worms, making it a versatile option in parasitic treatments. The drug is usually taken orally, often as a single dose or over several days, depending on the type of infection. For example, a single dose may be sufficient for common intestinal worms, while infections like neurocysticercosis require longer courses. Albendazole is generally well-tolerated, but some patients may experience mild side effects, such as nausea, abdominal pain, headache, or dizziness. Rarely, liver function abnormalities can occur, so monitoring may be recommended for prolonged therapy. Albendazole is particularly important in areas where parasitic infections are prevalent, as it can significantly reduce morbidity, especially in children. It is often included in mass deworming programs. To maximize effectiveness, it is advised to take Albendazole with a fatty meal, which improves absorption. Overall, Albendazole is a safe, effective, and widely used medication for controlling worm infections in humans.
