1. What Tenormin is and what it is used for
Tenormin contains a medicine called atenolol. This belongs to a group of medicines called beta-blockers. Tenormin is used to:
• Treat high blood pressure (hypertension)
• Treat uneven heart beats(arrhythmias)
• Help prevent chest pain (angina)
• Protect the heart in the early treatment after a heart attack (myocardial infarction).
It works by making your heart beat more slowly and with less force.
2. What you need to know before you take Tenormin Do not take Tenormin:
• If you are allergic to atenolol or any of the other ingredients of this medicine (listed in section 6)
• If you have ever had any of the following heart problems:
- heart failure which is not under control (this usually makes you breathless and causes your ankles to swell)
- second -or third-degree heart block (a condition which may be treated by a pacemaker)
- very slow or very uneven heart beats, very low blood pressure or very poor circulation.
• If you have a tumour called phaeochromocytoma that is not being treated. This is usually near your kidney and can cause high blood pressure. If you are being treated for phaeochromocytoma, your doctor will give you another medicine, called an alpha-blocker, to take as well as Tenormin.
• If you have been told that you have higher than normal levels of acid in your blood (metabolic acidosis).
Do not take Tenormin if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Tenormin.

• You have asthma, wheezing or any other similar breathing problems, or you get allergic reactions, for example to insect stings. If you have ever had asthma or wheezing, do not take this medicine without first checking with your doctor.
• You have a type of chest pain (angina) called Prinzmetal's angina.
• You have poor blood circulation or controlled heart failure.

• You have problems with your kidneys. You may need to have some check-ups during your treatment.
• If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking Tenormin.
Other medicines and Tenormin
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines that you buy without a prescription and herbal medicines.
This is because Tenormin can affect the way some other medicines work and some medicines can have an effect on Tenormin.
In particular, tell your doctor if you are taking any of the following medicines:
• Clonidine (for high blood pressure or migraine). If you are taking clonidine and Tenormin together, do not stop taking clonidine unless your doctor tells you to do so. If you have to stop taking clonidine, your doctor will give you careful instructions about how to do it.
