What TOPROL-XL is used for
TOPROL-XL belongs to a group of medicines called beta-blockers.
TOPROL-XL tablets are used to treat heart failure. It is used in combination with other medicines to treat your condition.
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 helps the heart to beat more regularly.
Ask your doctor if you have any questions about why TOPROL-XL has been prescribed for you.
Your doctor will have explained why you are being treated with TOPROL-XL and told you what dose to take.
Your doctor may have prescribed this medicine for another reason.
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
TOPROL-XL is not addictive.

How to take TOPROL-XL
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How much to take
The usual starting dose is half a 23.75 mg or a whole 23.75 mg tablet once a day for one to two weeks. The dose is then usually doubled every second week up to a maximum dose of 190 mg once daily or to the highest tolerated dose.
TOPROL-XL tablets may be broken in half or swallowed whole with a glass of water as directed by your doctor. TOPROL-XL tablets should not be chewed or crushed.
If you are taking other medicines your doctor may need to change the dose of them to obtain the best results for you.
When to take TOPROL-XL
Take your medicine at about the same time each day, preferably together with the morning meal.
Taking it at the same time each day will have the best effect. It will also help you remember when to take it.
How long to take TOPROL-XL
Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it.
It is important to keep taking your medicine even if you feel well.
DO NOT STOP TAKING TOPROL-XL TABLETS SUDDENLY.
The dose needs to be reduced slowly over 7 to 14 days to make sure that your condition does not get worse. Your doctor will tell you how to gradually reduce the dose before stopping completely.
If you forget to take it
If you forget to take a dose of TOPROL-XL, skip the dose you missed and take your next dose when you are meant to.
Do not take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.
Telephone your doctor, the Poisons Information Centre (13 11 26) or go to casualty at your nearest hospital immediately if you think that you or anyone else may have taken too much TOPROL-XL. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too many TOPROL-XL tablets your blood pressure may drop too far. You will feel faint or may faint, and your heart rate will also slow down. You may also have nausea, vomiting and shortness of breath. In extreme cases, serious heart and lung problems may occur.
While you are using TOPROL-XL
Things you must do
Be sure to keep all of your doctor's appointments so that your progress can be checked.
If you become pregnant while taking TOPROL-XL, tell your doctor immediately.
If you have a severe allergic reaction to foods, medicines or insect stings, tell your doctor immediately.
If you have a history of allergies, there is a chance that TOPROL-XL may cause allergic reactions to be worse and harder to treat.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
You may feel light-headed or dizzy when you begin to take TOPROL-XL. This is because your blood pressure has fallen suddenly.
Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem gets worse or continues, talk to your doctor.
If you feel a worsening of your condition in the early stages of taking TOPROL-XL, tell your doctor immediately.
Some people may experience an apparent worsening of their condition in the early stages of treatment with TOPROL-XL. It is important to tell your doctor if this happens to you, although it is usually temporary. If your condition continues to worsen, you should see your doctor as soon as possible.
Make sure you drink enough water during exercise and hot weather when you are taking TOPROL-XL, especially if you sweat a lot.
If you do not drink enough water while taking TOPROL-XL, you may feel faint or light-headed or sick. This is because your blood pressure is dropping too much. If you continue to feel unwell, tell your doctor.
If you are being treated for diabetes, make sure you check your blood sugar level regularly and report any changes to your doctor.
TOPROL-XL may change how well your diabetes is controlled. It may also cover up some of the symptoms of low blood sugar (hypoglycaemia). TOPROL-XL may increase the time your body takes to recover from low blood sugar. Your doses of diabetic medicines, including insulin, may need to change.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking TOPROL-XL.
Tell any doctors, dentists, and pharmacists who are treating you that you are taking TOPROL-XL.
If you plan to have surgery (even at the dentist) that needs an anaesthetic, tell your doctor or dentist that you are taking TOPROL-XL.
If you have to have any medical tests while you are taking TOPROL-XL, tell your doctor.
TOPROL-XL may affect the results of some tests.
Things you must not do
Do not stop taking TOPROL-XL without checking with your doctor.
Your doctor may want you to gradually reduce the amount of TOPROL-XL you are taking before stopping completely. This may help reduce the possibility of your condition worsening or other heart complications occurring.
Do not give TOPROL-XL to anyone else even if they have the same condition as you.
Do not use TOPROL-XL to treat any other complaints unless your doctor tells you to.
Things to be careful of
Be careful driving or operating machinery until you know how TOPROL-XL affects you.
As with other beta-blocker medicines, TOPROL-XL may cause dizziness, light-headedness, tiredness, or drowsiness in some people. Make sure you know how you react to TOPROL-XL before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed.
Be careful drinking alcohol while you are taking TOPROL-XL.
If you drink alcohol, dizziness or light-headedness may be worse.
Dress warmly during cold weather, especially if you will be outside for a long time (for example when playing winter sports).
TOPROL-XL, like other beta-blocker medicines, tends to decrease blood circulation in the skin, fingers and toes. It may make you more sensitive to cold weather, especially if you have circulation problems.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking TOPROL-XL.
If you get any side effects, do not stop taking TOPROL-XL without first talking to your doctor.
