■ Do I have or have I ever suffered from kidney disease?
■ Do I suffer from psoriasis or allergic reactions?

• Do I have a history of serious allergic reaction (anaphylactic) which causes difficulty breathing or dizziness? Your usual doses of adrenaline (epinephrine) used to treat allergic reactions may not work.
Special precautions?
Do not suddenly stop taking Atenolol Tablets BP. If you need to stop this medicine, you should do so gradually over a period of 7 - 14 days. You should be monitored by your doctor whilst stopping, especially if you have heart disease.
If you are due to have surgery and your doctor decides to stop your treatment with Atenolol, this should be done at least 24 hours before the operation. (Also see 'Other medicines' and concurrent use with anaesthetics).
Effect on ability to drive
Your medicine is unlikely to affect your ability to drive. However some people may occasionally feel dizzy or tired when taking Atenolol. If this happens ask your doctor or pharmacist for advice.
Pregnancy
If you are pregnant or are planning to become pregnant, you should talk to your doctor about whether or not you can take Atenolol Tablets BP.
Breastfeeding
As this medicine will get into your milk, you should talk to your doctor before breastfeeding.
Other medicines
Always tell your doctor or pharmacist if you are taking other medicines because taking some medicines in combination with others can be harmful.
Concurrent use of anaesthetics may increase the risk of problems with the heart and low blood pressure (hypotension). You must tell the medical staff that you are taking Atenolol.
If you are taking verapamil, diltiazem or nifedipine for high blood pressure or chest pain, it may cause severe low blood pressure, slow heart beat and heart failure.
If you are taking digitalis glycosides, such as digoxin, it may increase your heart beat rate.
If you are taking clonidine for high blood pressure or migraine, it may make your high blood pressure worse when you stop taking clonidine. If you are taking clonidine and atenolol 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.
If you are taking anti-arrhythmic medicines for an irregular heartbeat, such as disopyramide and amiodarone, it may affect your heart beat.
If you are taking adrenaline (epinephrine), a medicine which stimulates the heart, it may decrease the effect of atenolol
If you take insulin or oral medicines for diabetes, the risk of developing low blood sugar levels (hypoglycaemia) may be increased. Betablockers, such as atenolol may mask certain symptoms which occur when low blood sugar levels (hypoglycaemia) develop, in particular, a faster heart beat
If you take non-steroidal anti-inflammatory agents such as ibuprofen or indometacin,for pain and inflammation, the blood pressure lowering (antihypertensive) effect may be reduced.
