Standard Adult Dosing:
- Regular strength (325 mg tablets): 1-2 tablets every 4-6 hours
- Extra strength (500 mg tablets): 1-2 tablets every 6 hours
- Maximum daily dose: 3000-4000 mg (depending on formulation)

- 500 mg tablets: Maximum 6 tablets per day (3000 mg)
Important Considerations
Safety Precautions:
- Hepatotoxicity risk: Acetaminophen can cause liver damage when taken in excess 1
- Patients with liver disease should use lower doses (consult healthcare provider)
- Avoid alcohol consumption while taking acetaminophen
Common Pitfalls to Avoid:
- Many patients don't recognize acetaminophen as an ingredient in combination products 2
- Taking multiple acetaminophen-containing products simultaneously (prescription and OTC) can lead to unintentional overdose
- Poor understanding of maximum daily dose limits is common among patients 2
Special Populations
Elderly:
- Start at lower end of dosing range
- Consider reduced maximum daily dose (3000 mg)
Patients with Liver Disease:
- Reduce maximum daily dose
- Consider alternative pain management options if appropriate
Efficacy Considerations
- Acetaminophen is effective for mild pain as a first-line agent 1
- For moderate to severe pain, acetaminophen may be combined with other analgesics 1
- Limited evidence supports efficacy for chronic pain conditions 3
Patient Education Points
- Take only as directed
- Check all medication labels for acetaminophen content
- Track total daily acetaminophen intake from all sources
- Do not exceed recommended maximum daily dose
- Seek medical attention for severe or persistent pain not responding to acetaminophen
Remember that acetaminophen is often found in combination products for pain, cold, and flu, which can lead to unintentional overdose if patients are not aware of all sources of acetaminophen in their medication regimen.
