For common intestinal worm infections in adults, the standard dose of albendazole is a single 400 mg tablet. For certain infections like pinworms, a second dose is typically repeated after two weeks to prevent reinfection. For deeper, systemic infections, treatment duration can range from 8 to 30 days depending on the specific parasite. It is best to take albendazole with a fatty meal (like milk or food) to help your body absorb the medicine effectively. The tablet can be chewed, swallowed, or crushed. Always complete the exact course prescribed by your doctor to ensure the infection is fully cleared.
