Albendazole is a broad-spectrum antiparasitic medication commonly used to treat a variety of worm infections in humans. It works by preventing parasites from absorbing glucose, which ultimately weakens and destroys them. Albendazole is frequently prescribed for conditions such as roundworm, hookworm, whipworm, and pinworm infections. Albendazole 400 mg  is also used in certain tissue-invading parasitic diseases, including neurocysticercosis and echinococcosis, under the supervision of a healthcare professional. The medication is typically taken orally, and treatment duration depends on the specific type of worm involved. Albendazole is often chosen because it is effective, generally well tolerated, and considered safe for most adults and children when used as directed. Common side effects may include mild stomach discomfort, headache, or dizziness. Rarely, more serious reactions can occur, especially during long-term use, so medical monitoring may be required for extended treatments.Albendazole should only be used when a healthcare provider confirms a parasitic infection, as the symptoms of worm infections can resemble other unrelated conditions. It is important to follow all medical instructions carefully and report any unusual symptoms. Good hygiene practices, proper food handling, and clean living environments can help prevent reinfection and support successful treatment.
