Beta-blockers

Common tablets

Atenolol, Propanolol, Bisoprolol, Metoprolol

Why are they used?

Beta-blockers are used for a number of reasons. They are used to reduce high blood pressure, reduce the symptoms of angina and regulate fast heart rhythms. After a heart attack, they also reduce the risk of further heart attacks.

How do they work?

These medications 'block' the beta-receptors in the body. Beta-blockers slow your heart down and lower your blood pressure. They ease the workload on the heart and protect against a 'racing' heart.

What to look out for

When first taking these tablets, you may feel tired and lethargic. This usually resolves after a few weeks.
A common problem you may experience is a coldness in your hands and feet, especially in cold weather. To combat this problem, ensure you wrap up warm.
If you are a man, they may cause you to become impotent. If this occurs, please mention it to your practice nurse or your GP. Your doctor may decide to prescribe a different medication or to reduce the amount.
If you are a diabetic, the amount of insulin you require may be affected. Please note that they may mask the signs of a 'hypo' so it is important that you keep strict control of your blood sugar level.
In a very small number of people, beta-blockers can cause a wheeze or difficulty breathing. If this occurs you must contact your GP immediately.

Special instructions

Please try to take your beta-blocker at the same time every day. Do not stop taking your tablets unless instructed by your doctor.
