In this article we’ll discuss the possible side effects of ibuprofen, as well as who can and who shouldn’t take ibuprofen.

How does ibuprofen work?

Ibuprofen works by blocking the effect of natural chemicals (COX enzymes) that make other chemicals in the body, including prostaglandin. Prostaglandins are produced at the site of injury or damage, and cause pain and inflammation. Blocking of COX enzymes may also affect the protective barrier in the stomach, which is why some people may have stomach ulcers when taking ibuprofen for a long time. Over the counter ibuprofen products such as Nurofen Tablets are only intended for short-term use.

Does ibuprofen cause stomach issues?

Ibuprofen is unlikely to cause stomach problems if you take it as directed on the pack and you have not had the following:

  • stomach ulcers,
  • bleeding or a hole in your stomach,
  • Crohn’s disease, ulcerative colitis or Inflammatory Bowel Disease (IBD) such as Crohn’s disease and ulcerative colitis.

As with most medicines, some people may experience unwanted side-effects when taking ibuprofen. It’s important to read the package instructions before taking ibuprofen, as it may be unsuitable for people with certain types of conditions.

If I have stomach issues, should I avoid Ibuprofen?

It’s best to speak to your doctor before taking ibuprofen if you have ever had a stomach ulcer, stomach problems or inflammatory bowel disease (IBD)

You should also see your doctor if you need long-term pain relief. Long-term use of NSAIDs can cause stomach problems in some people. If you need to take ibuprofen tablets or capsules for a long time, your doctor may prescribe a medicine to help protect your stomach.

To make sure that ibuprofen is suitable for you, you should let your doctor know if you have ever had any of the following:

  • Stomach issues from taking ibuprofen before
  • A hole, bleeding or ulcers in the stomach
  • Crohn’s disease or ulcerative colitis
  • A health condition that means you bleed easily
  • Severe heart, kidney or liver failure or heart, kidney or liver problems
  • Uncontrolled high blood pressure
  • Asthma, hay fever or allergies or an allergic reaction when taking ibuprofen

You should also let your doctor know, before taking ibuprofen if:

  • You’re pregnant or trying to get pregnant.
  • You have chickenpox or shingles.
  • You’re over the age of 65

Why does ibuprofen bother my stomach?

NSAIDs like ibuprofen block a certain chemical in the body called prostaglandins, that not only trigger pain and inflammation, but also trigger protective mechanisms in the stomach. This is why some people may have stomach side effects when taking ibuprofen, such as indigestion, heartburn, stomach pain, nausea, vomiting or diarrhoea.
