What this medicine is used for
The name of your medicine is Terry White Chemists Metoprolol. It contains the active ingredient metoprolol.
It is used to:
- lower higher blood pressure (hypertension)
- prevent angina (a type of chest pain)
- treat or prevent heart attacks, or reduce the risk of heart complications following a heart attack (myocardial infarction)
- prevent migraines.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Metoprolol belongs to a group of medicines called beta-blockers.
It works by affecting the body's response to some nerve impulses, especially in the heart. As a result, it decreases the heart's need for blood and oxygen and therefore reduces the amount of work the heart has to do. It also widens the blood vessels in the body, causing blood pressure to fall.
There is no evidence that this medicine is addictive.
Use in children
This medicine should not be used in children.

How long to take it for
Continue taking your medicine for as long as your doctor tells you.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.

While you are taking this medicine
Things you must do
Tell your doctor that you are taking this medicine if:
- you are about to be started on any new medicine
- you plan to have any vaccinations or immunisations
- you are pregnant or are planning to become pregnant

- you have an allergic reaction to a food, another medicine or an insect sting while you are taking this medicine.
If you are being treated for diabetes, make sure you check your blood sugar level regularly and report any changes to your doctor.
Metoprolol may change how well your diabetes is controlled. It may also cover up some of the symptoms of low blood sugar, called hypoglycaemia, such as fast heart beat. It may make low blood sugar last longer. Your doses of diabetic medicines may need to change.
Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for a check-up.
Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.
Things you must not do
- Give this medicine to anyone else, even if their symptoms seem similar to yours.
- Take your medicine to treat any other condition unless your doctor tells you to.
- Stop taking your medicine, or change the dosage, without first checking with your doctor.
Things to be careful of
Be careful when driving or operating machinery until you know how this medicine affects you.
As with other beta-blocker medicines, this medicine may cause dizziness, light-headedness or decreased alertness in some people.
If you have any of these symptoms, do not drive or do anything else that could be dangerous. If these symptoms do not go away, talk to your doctor.
Be careful to dress warmly during cold weather, especially if you will be outside for a long time. Like other beta-blocker medicines, this medicine may make you more sensitive to cold temperatures, especially if you have problems with your blood circulation. These medicines tend to decrease blood circulation in the skin, fingers and toes.
