What is the MAX daily dosage of Acetaminophen per day?

• A. 2.0 mg/kg
• B. 6.0 mg/kg
• C. 8.0 mg/kg
• D. 4.0 mg/kg

Answer: (D)

The crucial idea is limiting total daily exposure to acetaminophen to prevent liver injury. For adults, the safe upper limit is 4,000 mg (4 g) in 24 hours. When you think about this in terms of body weight, that total translates roughly to about 60–75 mg per kilogram of body weight per day, depending on how much a person weighs. In practice, dosing is given per dose (commonly 325–1000 mg) every 4–6 hours, and you must not exceed 4,000 mg in a single day. So, none of the per-kilogram values listed map neatly onto the standard daily maximum for an average adult. The guideline to remember is that the daily cap is 4,000 mg, with the per-kilogram figure being a weight-adjusted reflection of that total.
