Albendazole 400 mg is not usually taken daily. The correct dose depends entirely on the specific worm or parasitic infection, with common intestinal worm infections typically treated with a single 400 mg dose while certain other infections may require once or twice daily dosing for a set number of days under medical supervision; alternatives like mebendazole or ivermectin may be used depending on the type of infection, but a doctor should guide you on all options to ensure safe and effective treatment tailored to your needs.
