Standard maximum: 4,000 mg (4 g) per 24 hours for a healthy adult — this is the FDA-labeled ceiling.

Practical dosing:

• •325–1,000 mg every 4–6 hours
• •No more than 1,000 mg in a single dose
• •Many manufacturers (including Tylenol) now recommend a 3,000 mg/day limit for over-the-counter use as an added safety margin, and many clinicians suggest 2,000–3,000 mg/day for regular or long-term use.

Lower limits apply if you:

• •Have liver disease, hepatitis, or cirrhosis
• •Drink alcohol regularly (3+ drinks/day)
• •Weigh under ~50 kg (~110 lb) — dose by weight instead
• •Are malnourished, fasting, or dehydrated
• •Take warfarin or certain anti-seizure medications

The biggest real-world risk is accidental double-dosing. Acetaminophen (also called paracetamol or APAP) is hidden in hundreds of products: cold and flu remedies, sleep aids, menstrual formulas, and prescription opioid combinations like Percocet, Vicodin, and Norco. Always check labels and add up your total from all sources.

Overdose can cause severe liver injury, sometimes with few symptoms for the first 24 hours. If you suspect an overdose, don't wait for symptoms — call Poison Control (1-800-222-1222 in the US) or go to an emergency department, since the antidote works best early.

For your specific situation, it's worth confirming with your pharmacist or doctor — they can account for your other medications and health history.
