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.
If you are a smoker, when the blood level of nicotine falls, you usually develop withdrawal symptoms such as restlessness, increased appetite, inability to concentrate, irritability, dizziness, constipation, nicotine craving, or just feeling awful. These symptoms begin within a few hours after having the last cigarette. If they are not relieved by the next cigarette, withdrawal symptoms get worse. If you do not smoke any more cigarettes, the withdrawal symptoms peak after about 24 hours, and then gradually ease over about 2-4 weeks. So, most smokers smoke regularly to feel 'normal', and to prevent withdrawal symptoms.
About 2 in 3 smokers want to stop smoking but, without help, many fail to succeed. The main reason why so few smokers succeed, even though they want to stop smoking, is because nicotine addiction is strong and difficult to break. This is where bupropion can help.
Zyban is a medicine that was first developed to treat depression. It was found that it helped smokers to stop smoking. It is not clear how it works. It alters the level of some chemicals in the brain (neurotransmitters). This seems to relieve the withdrawal symptoms that you get when you stop smoking (such as craving, anxiety, restlessness, headaches, irritability, hunger, difficulty with concentration, or just feeling awful).
This is a non-nicotine, prescription-strength medication to help you quit smoking. While it's unclear exactly how Zyban works, Zyban is thought to work on the chemicals in the brain. It helps reduce the urge to smoke, and lessens symptoms of withdrawal. Your chances of quitting with Zyban greatly depend on your commitment to quitting.
Zyban helps reduce your urge to smoke and can make quitting bearable. You may continue to smoke after you begin to take Zyban. Then you and your health care professional will set a quit date, usually 8 to 14 days after your first dose of Zyban. When your quit date arrives, you stop smoking and continue taking Zyban.
