• If you have low blood pressure or poor circulation.
• If you have asthma or breathing difficulties.
• If you have diabetes.
• If you have psoriasis (a skin problem).
• If you have myasthenia gravis (a condition causing muscle weakness).
• If you have heart failure (a condition where the pumping action of the heart is reduced) or heart block (a slow and irregular heartbeat).
• If you have been told you have Prinzmetal's angina (chest pain caused by spasms of the heart's blood vessels).
• If you have phaeochromocytoma (a tumour on your adrenal gland).

• If you have ever had an allergic reaction to a medicine, or if you have ever had any other severe allergic reaction.

How to take nadolol

• Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
• Take nadolol exactly as your doctor has told you. You may be asked to take a small dose at first and then increase it gradually.
• Nadolol is taken once each day. Try to take your dose at the same time each day to avoid missing any doses.
• If you do forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the missed dose. Do not take two doses together to make up for a forgotten dose.

Getting the most from your treatment

• Try to keep your regular appointments with your doctor. This is so your progress can be monitored.
• It is very important to follow any dietary advice that you may have been given by your doctor.
• It is recommended that you avoid drinking alcohol while you are taking nadolol, as it may increase some of its side-effects.
• If you have diabetes, check your blood glucose levels regularly as this medicine can affect the levels of sugar in your blood. It may also block the symptoms of low blood sugar.
• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking nadolol.
• Do not stop taking this medicine unless your doctor tells you to stop. Stopping treatment suddenly can cause problems in some people and your doctor will probably want you to reduce your dose gradually if this is necessary.
• If you buy any medicines, check with a pharmacist that they are safe to take with nadolol.
