What does it do?

Metoprolol is used to treat some heart problems and high blood pressure. It is also sometimes used for other conditions such as migraines.

Before you start

• Tell your doctor if you have liver or circulation problems, asthma or diabetes.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take metoprolol regularly as directed with a glass of water.
The controlled release (CR) or sustained release (SR) tablets may be halved if needed, but do not crush or chew them.

What if you forget a dose?

Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with metoprolol including:

• anti-inflammatories, such as diclofenac (e.g. Voltaren®), ibuprofen (e.g. Nurofen®), or aspirin (e.g. Disprin®, in doses used for pain relief). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).
• diphenhydramine (e.g. Unisom SleepGels®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
