Can I take Ibuprofen and Side effects together?

Drug interaction guide

Ibuprofen is a medication used to treat pain and inflammation, but it can cause its own side effects. When we talk about 'interactions' with side effects, we usually mean that ibuprofen can make existing health problems worse or increase the risk of certain symptoms occurring. Common side effects include stomach irritation, indigestion, and, in some cases, reduced kidney function or increased blood pressure.

Why this happens

Ibuprofen works by blocking enzymes called COX-1 and COX-2. While this reduces pain, it also reduces the protective lining of the stomach and affects blood flow to the kidneys. This is why it can cause stomach ulcers or fluid retention.

Always take ibuprofen with food or a glass of milk to protect your stomach. Do not take more than the recommended dose. If you have a history of stomach ulcers, asthma, high blood pressure, or kidney problems, speak to your doctor or pharmacist before using it. If you notice black, tarry stools or severe stomach pain, stop taking it immediately and seek medical help.

Asthma

Do not take this medicine if you have asthma, as it can cause a life-threatening worsening of your breathing or a severe allergic reaction.

Stomach ulcers or bleeding

Avoid this medicine if you have ever had a stomach ulcer, perforation, or bleeding. It can cause serious damage to the stomach lining, even after a few doses.

Pregnancy (third trimester)

Do not take ibuprofen if you are more than 20 weeks pregnant. It can cause serious heart and kidney problems in the unborn baby and reduce amniotic fluid levels.

Alcohol

Drinking alcohol while taking ibuprofen can increase the risk of stomach irritation and bleeding. It is best to limit or avoid alcohol, especially if you are taking ibuprofen long-term or at high doses.
