About bupropion

Nicotine is a drug that is inhaled from the tobacco in cigarettes. It gets into the bloodstream, and stimulates the brain. Most regular smokers are addicted to nicotine. Even though you want to parar de fumar, it can be difficult to succeed, because nicotine addiction is strong and hard to break. This is where bupropion can help.

Stopping smoking in somebody who smokes regularly causes a reduction of some chemicals in the brain. This leads to withdrawal symptoms such as cravings, anxiety, irritability and other symptoms associated with 'giving up'. Bupropion alters the levels of some of these chemicals and this is possibly how it relieves the withdrawal symptoms.

Bupropion does not 'make' you stop smoking. You still need determination to succeed and to break the smoking habit. A combination of bupropion with counselling from a nurse, doctor, pharmacist, or other health professional increases your chance of successfully stopping smoking. Therefore, most doctors will only prescribe bupropion to people who really want to stop smoking as part of a 'stopping smoking' programme.

Bupropion is also available as a combination product to support weight loss. If you are taking bupropion for this purpose and you need additional information, ask your pharmacist or doctor for advice.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking bupropion it is important that your doctor knows:

• If you are under 18 years of age, or over 65 years old.

• Se você está grávida ou amamentando.

• Se você tiver algum problema com o funcionamento do seu fígado, ou qualquer problema com o funcionamento dos seus rins.

• Se você tem diabetes (diabetes mellitus).

• Se por algum motivo você estiver em risco de ter uma convulsão.

• If you have ever had an eating disorder, such as anorexia nervosa or bulimia.

• If you have bipolar disorder.

• If you have an inflammatory condition called systemic lupus erythematosus (also called lupus, or SLE).

• If you regularly drink a lot of alcohol or if you have a drug problem.

• If you have been told you have a tumour of the brain or spinal cord, or if you have ever had a serious head injury.

• If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines. This is particularly important if you are taking digoxin for a heart condition. Your dose of digoxin may need to be adjusted before or after treatment with bupropion.

• Se você já teve uma reação alérgica a um medicamento.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about bupropion and stopping smoking. It will also provide you with a full list of the side-effects which can be associated with bupropion.

• Take bupropion exactly as your doctor tells you to. You will be asked to set yourself a date on which to stop smoking. Your doctor will then ask you to start taking bupropion tablets at least a week before this 'quit' date. The aim is to build up the dose so that your body gets used to the medicine before your quit date.

• Start by taking one tablet (150 mg) each day for the first six days. Then from day seven onwards, take one tablet twice a day (unless you are told otherwise by your doctor). Make sure that you leave at least eight hours between the doses. Ideally, take one tablet in the morning and one early evening. Remember to stop smoking on the day you have set as your quit date.

• It is not important whether you take bupropion tablets before or after food, but it is best if you try to take your doses at the same time(s) each day. This will help you to remember to take the tablets regularly.

• Swallow the tablets whole with a glass of water - do not chew or break the tablets before you swallow.

• If you forget to take a dose, leave out the missed dose but make sure that you remember to take your next dose when it is due. Do not take two doses together to make up for the forgotten dose.

• Try to keep your regular appointments with your doctor or nurse. This is so that you can be given counselling and encouragement, and also so that a check can be kept on your progress. You will also need to have your blood pressure measured regularly, as this can increase in some people.

• Certifique-se de que seu médico ou profissional de saúde saiba se você está tomando outros medicamentos. Isso porque parar de fumar pode alterar a forma como seu corpo metaboliza certos medicamentos. Portanto, ao parar de fumar, a dose de alguns medicamentos prescritos pode precisar ser ajustada.

• A full course of treatment with bupropion will last for 7-9 weeks in total. If you are still smoking after seven weeks, let your doctor know about this so that you can discuss the options that are available to you.

• After your course of treatment, your doctor may suggest that you gradually reduce the dose over a few days before you finally stop taking the tablets.

• Se você comprar qualquer medicamento, sempre verifique com um farmacêutico se é seguro tomá-lo com seus outros medicamentos.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.
