Can I take Propranolol and Ibuprofen together?

Why this happens

Propranolol works by blocking certain receptors to lower blood pressure. Ibuprofen belongs to a group of drugs (NSAIDs) that cause the body to retain salt and water and can narrow blood vessels in the kidneys. These actions directly oppose the blood-pressure-lowering effects of propranolol.

What you should do

If you only need a single dose of ibuprofen, the risk is low. However, if you need regular pain relief, speak to your doctor or pharmacist. They may suggest an alternative like paracetamol. If you must take both, monitor your blood pressure regularly and watch for signs of fluid retention, such as swollen ankles.

Important precautions

Asthma or COPD

You must not take propranolol if you have asthma or a history of wheezing. It can cause a life-threatening narrowing of the airways (bronchospasm).

Stomach ulcers or gastritis

Do not take ibuprofen if you have ever had a stomach ulcer, perforation, or bleeding. It significantly increases the risk of serious internal bleeding.

Pregnancy (third trimester)

Do not take ibuprofen if you are more than 28 weeks pregnant. It can cause serious heart and kidney problems in the unborn baby and complications during birth.

Food and drink warnings

Alcohol

Drinking alcohol while taking propranolol can increase the medicine's blood-pressure-lowering effect, which may make you feel dizzy or lightheaded. It is best to limit or avoid alcohol, especially when you first start treatment or if your dose is increased.

Caffeine

Propranolol is often used to treat physical symptoms of anxiety or heart palpitations. Caffeine (found in coffee, tea, and energy drinks) is a stimulant that can increase your heart rate and blood pressure, potentially working against the effects of your medicine.

Food (General)

Propranolol can be taken with or without food, but you should be consistent. Taking it with food can increase the amount of medicine absorbed by your body. It is best to always take it the same way (either always with food or always without) to keep your blood levels steady.
