• If you have diabetes.
• If you have epilepsy or any other condition which causes seizures (fits).
• If you have ever had an eating disorder, such as anorexia nervosa or bulimia.
• If you have bipolar disorder.
• If you have an alcohol or drug problem.
• If you have a tumour in your brain, spine or nervous system.

How to take bupropion

• Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
• Take bupropion exactly as your doctor has told you. If you are elderly or if you have certain liver or kidney diseases, your dose may be different to below and your doctor will advise you if this is the case.
• Start by taking one tablet (150 mg) each day for six days. Then increase to one tablet twice a day, at least eight hours apart. Do not take more than one tablet at any one time, and do not take more than two tablets in a day. Aim to stop smoking completely on day eight of treatment. This allows bupropion to build up in your body before you stop smoking. You should then continue the tablets for a further seven weeks.
• The tablets should be swallowed whole with a drink of water, and should not be crushed or chewed.
• You can take bupropion tablets before or after meals.
• Try to take bupropion at the same time(s) each day to avoid missing any doses.
• If you do forget to take a dose, do not worry, just take the next dose when it is due. 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 doctor can check on your progress. Your blood pressure may need to be measured while taking this medicine.
• Bupropion will help you to give up smoking, but you still need determination to succeed and to break the smoking habit. If you are still smoking after seven weeks, discuss this with your doctor.
• Bupropion may affect your concentration and cause you to feel dizzy. If this happens, do not drive or use tools or machines.
• Speak with your doctor for advice about taking bupropion and alcohol. You may be advised not to drink alcohol while you are being treated with bupropion.
• If you buy any medicines, check with a pharmacist that they are safe to take with bupropion.
• This medicine is for you. Never give it to others, even if their condition appears to be the same as yours.

Can bupropion cause problems?
