1. WHAT ATENOLOL IS FOR


Atenolol belongs to a group of medicines called beta-blockers. It is used to:

•    control high blood pressure (hypertension)

•    relieve chest pain (angina pectoris)

•    control irregular heart beat

•    protect the heart if taken shortly after a heart attack.


2. BEFORE YOU TAKE ATENOLOL


Do not take Atenolol and tell your doctor if you:

•    are allergic to Atenolol or any of the other ingredients in the tablets (listed in section 6 of this leaflet)

•    have ever had any of the following heart problems:

-    heart failure which is not under control (this usually makes you breathless and causes ankle swelling)

-    second or third degree heart block (conditions which may make you feel dizzy and light-headed, tired and prone to collapses)

-    very slow or very uneven heart beats, very low blood pressure or severe blood circulation problems

-    a problem (common in the elderly) related to poor control of the working of the heart (sick sinus syndrome)

-    failure of the heart to maintain adequate circulation of the blood (cardiogenic shock)

•    have been told that you have increased levels of acid in your blood (metabolic acidosis)

•    have a tumour called phaeochromocytoma, which is not being treated (this is usually near the kidney and can cause high blood pressure).

Take special care with Atenolol

Tell your doctor before you take this medicine if you

•    have asthma, wheezing or any other similar breathing problems. If you have ever had asthma or wheezing, do not take this medicine without first checking with your doctor

•    have a history of allergic reactions

•    have lung problems

•    have a type of chest pain called Prinzmetal's angina

•    have heart failure which is controlled

•    have first degree heart block, which is detected by having a tracing of the heart (ECG)

•    suffer from blood circulation problems, which can cause calf pain on walking, as Atenolol may make this worse

•    are elderly or have kidney problems, as you may need a lower dose of Atenolol

•    have diabetes, as symptoms of low blood sugar levels (hypoglycaemia) may be hidden by this medicine


•    have high levels of thyroid hormone in your body (thyrotoxicosis), as Atenolol may hide the symptoms of thyrotoxicosis

•    are being treated for phaeochromocytoma, as your doctor will give you another medicine, called an alpha-blocker, to take as well as Atenolol.

Taking other medicines

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, even medicines bought without a prescription.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines, as they may affect how Atenolol works:

•    Medicines for high blood pressure or chest pain, such as Diltiazem, Verapamil, Nifedipine, Nisoldipine, Ramipril or Diuretics (e.g. Furosemide)

•    Clonidine for high blood pressure or migraines. Do not stop taking Clonidine unless your doctor tells you to. If you have to stop taking Clonidine, your doctor will tell you how to

•    Medicines to treat irregular or uneven heart beat, such as Amiodarone, Disopyramide, Quinidine or Digoxin

Adrenaline for stimulating the heart

•    Moxisylyte for blood circulation problems like Raynaud's disease

•    Insulin or oral anti-diabetic medicines, such as Metformin

•    Medicines for pain and swelling, such as Ibuprofen or Indometacin

•    Theophylline, used for asthma

•    Cough or cold remedies bought over the counter

•    Calcium or Aluminium hydroxide for indigestion

•    Medicines for depression, such as MAO inhibitors (e.g. Moclobemide)

•    Phenothiazines (e.g. Chlorpromazine) for mental health problems or nausea (feeling sick)

AVOID ALCOHOL whilst taking this medicine.

Operations

If you go into hospital to have an operation, tell the anaesthetist or medical staff that you are taking Atenolol. This is because you can get low blood pressure (hypotension) if you are given certain anaesthetics while you are taking Atenolol.

Pregnancy and breast-feeding

Do not take Atenolol if you are pregnant, planning to become pregnant or are breast-feeding, unless your doctor has told you to.
