Labetalol - a beta-blocker

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking labetalol it is important that your doctor knows:

• If you are pregnant or breast-feeding.
• If you have asthma or any other breathing disorder.
• If you have any problems with the way your liver works.
• If you have poor circulation.
• If you have sugar diabetes (diabetes mellitus).
• If you have a skin problem called psoriasis.
• If you have a condition causing muscle weakness, called myasthenia gravis.
• If you have been told you have a slow heartbeat, heart failure, or heart block (a slow and irregular heartbeat).
• If you have been told you have chest pain caused by spasms of your heart's blood vessels, called Prinzmetal's angina.
• If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
• If you have ever had an allergic reaction to a medicine, or if you have ever had any other serious allergic reaction.
