What's the maximum daily dose of acetaminophen for a healthy adult?For a healthy adult, the usual absolute maximum is 4,000 mg (4 g) of acetaminophen in 24 hours, from all products combined. Many clinicians recommend staying at or below 3,000 mg/day when possible, especially for repeated use.
- •Typical dose: 650–1,000 mg every 4–6 hours
- •Do not exceed label directions or combine multiple acetaminophen-containing medicines (often labeled APAP).
- •Lower limits may apply with liver disease, regular alcohol use, low body weight, malnutrition, or certain medications.
If you’ve exceeded 4,000 mg—or aren’t sure—contact Poison Control promptly (U.S.: 1-800-222-1222), even if you feel well.
