Zyban can be used to help stop smoking. It can be taken alone or in conjunction with other therapies to give up smoking. This medicine works on the chemistry of the brain to help alleviate the desire and cravings to smoke. Zyban is not a nicotine replacement product and does not contain any nicotine. This is a slow-release tablet that is taken over a period of 7-12 weeks. A smoker will usually have stopped smoking during the second week of taking this medicine. Zyban is only suitable for adults aged 18 and over who wish to give up smoking.
What is Zyban?
Zyban is the brand name for bupropion hydrocholoride, a medicine that helps people to stop smoking. Buproprion hydrochloride is the active ingredient in Zyban. This medicine comes in tablet form and you take it over a 7-12 week period as a stop-smoking programme.
It works by affecting the balance of chemicals in the brain to assist with stopping smoking. It does not usually work on its own to stop a person smoking. If you take Zyban you must be determined to stop smoking and set a day to stop (usually during the second week of taking this medication). It is recommended to use Zyban in conjunction with other stopping smoking techniques such as therapy and possibly nicotine replacement products (usally gum or patches) if your doctor thinks this will benefit you.
Stopping smoking can be difficult for many people as the nicotine in cigarettes acts as a drug. If you smoke you are likely to be addicted to nicotine. Zyban can make stopping smoking easier and manageable. However, there is also a certain degree of willpower needed when stopping smoking, along with support from family, friends, possibly group therapy and your doctor. How you stop smoking will depend on you and which method you feel most comfortable with.
Nicotine affects some of the neurotransmitters in the brain. These neurotransmitters (known as noadrenaline and dopamine) affect our mood and give us a sense of pleasure and reward (the same as those that give us pleasure when we eat or drink something we enjoy). It is believed Zyban keeps these neurotransmitters active and so reduces the desire to smoke.Bupropion (Zyban) was originally used as an anti-depressant medicine under the brand name of Wellbutrin. It was found that when people took Bupropion to treat depression their desire to smoke reduced. Zyban was approved as an aid to stopping smoking in 1997.
Note that Zyban is not a selective reuptake inhibitor (SSRI) which are the most common forms of anti-depressant medicines. These increase the levels of serotonin in a person’s brain. Zyban works in a different way. It is known as a norepinephrine-dopamine reuptake inhibitor (NDRI) which boosts the neurotransmitters in the brain. Bupropion is still used today as an anti-depressant medication, as well as to help stop smoking. It is also used to treat seasonal affective disorder (SAD), which is a form of depression that occurs at particular times of the year, usually during autumn and winter.
When is Zyban used?
Zyban is used when a person wants to give up smoking and is finding it hard to do so. Smoking is an addition to nicotine and giving up can be difficult. Once you start smoking it becomes a habit that can be very hard to break. Zyban can help reduce cravings for cigarettes and the desire to smoke. If you want to take Zyban in conjunction with nicotine replacement therapy it is important to speak to your doctor as they will advise you on the best way to do this. When you take Zyban to give up smoking you must also set a date on which you intend to stop. This is usually during the second week of taking this medication. This gives the Zyban an adequate amount of time to start working in your body and to begin to stop you having cravings to smoke. It is important to know that Zyban will not cause you to stop smoking overnight. You must follow a programme and take the medication regularly as prescribed in order to achieve successful results.
How do you use Zyban?
You should start to take Zyban as prescribed by your doctor one week before giving up smoking. Zyban does not immediately replace the need to smoke.It is important to set a program and planned date to stop smoking when you begin to take Zyban. You take Zyban tablets whole with water, with or without food. You should not chew the tablets, this leads to more side effects, possible even seizures.
When using Zyban in conjunction with giving up smoking it usually takes about 7-12 weeks to completely stop smoking. The average time period for stopping is 9 weeks. It is recommended to set a date for stopping during the second week of taking Zyban. You should tell your doctor about any other medication you are taking, including herbal medicines, before you start to take Zyban.
What dosages are there?
Zyban comes in 150 mg tablets. The usual dosage is:
- 1 x 150 mg tablet for six days (your doctor may vary this)
- 1 x 150 mg tablet twice a day for 7-12 weeks (depending on the advice of your doctor)
When you take two tablets per day it is important to leave a period of at least eight hours between the doses. You should also note that Zyban can cause problems with sleep, so we advise you to plan your second dose well before the time you go to bed. This means you must also work out when to take the first tablet, so you take it eight hours before the second. If you forget a dose do not take an additional tablet to make up for it. This could be dangerous and cause seizures. If you miss a dose you should wait until the next programmed time before you take another tablet.

Does Zyban interact with other medication?

In addition to telling your doctor about any medication you are taking you must inform them if you are taking any medication for depression.
