You can usually take up to 8 regular Panadol (paracetamol 500 mg) tablets in 24 hours as an adult, but never more than 4,000 mg (4 g) total per day.

Safe daily limits (adults)

  • Typical adult dose: 500–1,000 mg (1–2 tablets of 500 mg) every 4–6 hours as needed.
  • Maximum frequency: No more than 4 doses in 24 hours.
  • Absolute maximum: 4,000 mg (4 g) per day, which is 8 tablets of 500 mg.
  • Do not take doses closer than 4 hours apart.

For products like Panadol Extra (paracetamol plus caffeine), directions are similar: usually 2 tablets up to 4 times per day, not exceeding 8 tablets in 24 hours.

If you are under 16, pregnant, have liver or kidney problems, drink a lot of alcohol, or take other medicines that contain paracetamol, you may need a lower safe limit and must ask a doctor or pharmacist.

Why the limit matters

Paracetamol overdose can seriously damage the liver and may not cause severe symptoms right away, which is why “just a few extra” tablets can still be dangerous. Taking more than 4 g in 24 hours, or repeating high doses over several days, greatly increases the risk.

Common early warning signs of taking too much can include nausea, vomiting, not feeling well, abdominal pain, or confusion, but sometimes people feel almost normal at first.

Simple “rules of thumb”

  • Count all sources of paracetamol (cold/flu combos, prescription pain meds, etc.).
  • Stick to the lowest effective dose for the shortest possible time.
  • Do not use it for more than a few days in a row for pain or fever without medical advice.

Mini example

If each Panadol tablet is 500 mg:

  • 2 tablets at 8:00
  • 2 tablets at 12:00
  • 2 tablets at 16:00
  • 2 tablets at 20:00

That equals 8 tablets (4,000 mg) in 24 hours, which is the maximum ; you must not go over this.

When to get urgent help

Seek emergency care immediately (even if you feel okay) if:

  • You think you may have taken more than 4,000 mg in 24 hours.
  • You took an unknown amount, mixed multiple paracetamol products, or took repeated high doses over several days.

Prompt treatment after an overdose can prevent severe liver damage, but it works best if started early.

If you are unsure how many Panadol you have taken today, or have any symptoms that worry you, contact a doctor, local emergency department, or poison centre now.
