The maximum amount of acetaminophen that can generally be taken at once by a healthy adult is 1,000 mg (1 gram) per dose, with typical dosing intervals of every 4 to 6 hours. The maximum daily dose should not exceed 4,000 mg (4 grams) in total within 24 hours to avoid the risk of serious liver damage. Some guidelines recommend taking the lowest effective dose and not exceeding 3,000 mg per day for added safety.
