Paracetamol, also known as acetaminophen, is a medicine for fever and pain. It’s important to use the right amount to stay safe.

For Adults:

  • Tablets and capsules: 500mg or 1g.
  • Syrup: 120mg, 250mg, or 500mg in 5ml.
  • Powder: Mix with water to drink.
  • Suppositories: 60mg to 1g.
  • Usual dose: 500mg or 1g.
  • Don’t take more than 8 tablets (500mg each) in 24 hours.
  • Take tablets or capsules with water, with or without food.
  • Measure syrup with the cap.
  • Dissolve powder in water before drinking.
  • Insert suppositories gently.
  • Use for a day or two for short pain, and longer for chronic issues but don’t go over the dose limit.
  • If you forget a dose, take it as soon as you remember unless it’s almost time for the next one. Don’t double up.
  • Taking a bit more than the dose once in a while is usually okay, but don’t go over 8 tablets in 24 hours. Too much can hurt your liver.

For Children:

  • Infant syrup (120mg/5ml): Give 2.5ml to 10ml, up to four times a day.
  • Six plus (6+) syrup (250mg/5ml): Give 5ml to 10ml, up to four times a day.
  • For 2-month-old babies, usually, give 2.5ml of infant syrup or a 60mg suppository after shots.
  • Tablet doses for kids vary, up to four times a day.
  • Shake syrup well, use a measuring syringe or spoon, not a kitchen spoon.
  • Kids can take tablets with water, milk, or juice.
  • Insert suppositories gently.
  • Don’t give more than 4 doses in 24 hours and not longer than 3 days without a doctor’s okay.
  • Too much paracetamol is risky, especially if using more than one medicine with paracetamol in it. Get medical help if overdose.

General Info:

  • Paracetamol works for fever and mild to moderate pain.
  • Adults and kids over 12 should not take more than 4g a day.
  • Too much can cause liver failure.
