  • Ibuprofen is available in different brands and strengths.
  • The lower strength (200 mg) tablets can be bought from a supermarket or over-the-counter from a pharmacy. 
  • The higher strength tablets (400 mg, 600 mg, 800 mg) tablets can only be bought on prescription from a pharmacy.
  • The usual dose for adults is 200 mg to 400 mg 3 or 4 times daily if needed.
  • Do not take more than 1200 mg per day without checking with your doctor.
  • Use the lowest dose that works for you and stop as soon as you can.
  • The dose will be different to this if you have been prescribed a tablet which releases ibuprofen slowly; this is called a modified-released tablet.
  • Always follow the directions on the package or pharmacy label. If you are unsure about how much to take, check with your pharmacist.

How to take ibuprofen

  • Take ibuprofen with food or immediately after food, to prevent stomach upset.
  • Take ibuprofen with a full glass of water.
  • Swallow the tablets whole. Do not crush or chew them.
  • Usually you may only need to take ibuprofen for a short period of time, while you have pain or swelling.
  • Limit or avoid alcohol while you are taking ibuprofen. Alcohol can increase the risk of side effects. 
  • It is not harmful if you miss your ibuprofen dose. If you miss a dose, take it when you remember, with or after food. Do not take double the dose.

Take care with ibuprofen

  • For most people taking ibuprofen is safe. However, extra care is needed if you have high blood pressure, high cholesterol, diabetes, stomach ulcers or kidney problems or if you smoke. Discuss with your doctor whether taking ibuprofen is suitable for you. 
  • Non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen increase the chance of a heart attack or stroke, which can lead to death. These serious side effects can occur even in the first weeks of using an NSAID and the risk may increase the longer you are taking them.
  • The risk appears greater at higher doses (such as ibuprofen 2400 mg per day)so use the lowest effective amount for the shortest possible time. Seek medical attention immediately if you experience symptoms such as:
    • chest pain
    • shortness of breath or trouble breathing
    • sudden weakness or numbness in one part or side of the body
    • sudden slurred speech.
  • Some other medicines contain NSAIDs, including those used for colds, flu, so always read the labels and avoid taking multiple medicines that contain NSAIDs.
  • Also see Ibuprofen patient information guide  SafeRx, Waitemata DHB, 2013.

Precautions - before taking ibuprofen

  • Do you have high blood pressure or problems with your heart?
  • Do you have any problems with the way your kidneys or liver works?
  • Have you had stomach ulcers?
  • Are you pregnant or breast-feeding?
  • Do you have any breathing problems?

If so, it’s important that you tell your doctor before you start taking ibuprofen. Sometimes a medicine isn’t suitable for a person with certain conditions, or taking other medicines or it can only be used with extra care.
