in the brain that mediate the craving for smoking.

HOW
EFFECTIVE IS ZYBAN?
Clinical studies have shown that ZYBAN reduces the craving
for cigarettes as well as withdrawal symptoms associated
with smoking cessation to a significant degree when
compared with placebo. Reductions in the following withdrawal
symptoms were most pronounced: irritability, frustration
or anger, anxiety, difficulty concentrating, restlessness
and depressed mood. In clinical studies it has been
demonstrated that ZYBAN achieves the best results in
diminishing the withdrawal symptoms of nicotine, significant
reduction in craving for cigarettes and an elevated
abstinence rate in the long term. In addition, your
chances of quitting with ZYBAN greatly depend on your
commitment to quitting.

HOW
SHOULD I TAKE ZYBAN?
- The usual recommended dosage is to take one 150-mg
tablet in the morning for the first 3 days. On the fourth
day, begin taking one 150-mg tablet in the morning and
one 150-mg tablet in the early evening. Doses should
be taken at least 8 hours apart.
- Never take an "extra" dose of ZYBAN. If
you forget to take a dose, do not take an extra tablet
to "catch up" for the dose you forgot. Wait
and take your next tablet at the regular time. Do not
take more tablets than prescribed. This is important
so you do not increase your chance of having a seizure.
- It is important to swallow ZYBAN tablets whole. Do
not chew, divide, or crush tablets. You may take ZYBAN
with or without food.

HOW
LONG DO I REMAIN ON ZYBAN?
For most patients, it is recommend that you stay on
ZYBAN for at least 7 to 12 weeks to help support long-term
success. It may be necessary to stay on ZYBAN for a
longer period, depending upon the rapidity with which
you withdraw from nicotine. You've probably been smoking
for some time, and your body has become accustomed to
it. ZYBAN helps reduce withdrawal symptoms as you remove
cigarettes from your life. It's important to remain
on ZYBAN for at least 7 to 12 weeks but it may require
up to 6 months of therapy if your dependence on nicotine
is great.

AM
I ADDICTED TO CIGARETTES?
You may be addicted to cigarettes if you experience
one or more of the following signs:
- You continue to smoke despite the desire to quit.
- You have made a serious, but unsuccessful, attempt
to stop using tobacco or permanently reduce the amount
you use.
- Your attempts to stop smoking have led to physical
withdrawal symptoms, including a craving for tobacco,
anxiety, irritability, restlessness, difficulty concentrating,
headaches, drowsiness, and stomach upset.
- You develop a "tolerance" for tobacco. Smoking
the same number of cigarettes produces less effect over
time, making it necessary to increase the number of
cigarettes you smoke to achieve the desired sensation.
- You have continued to use tobacco even when you have
a serious physical problem (such as heart or lung disease)
that you know is worsened by tobacco.

they may suffer from symptoms that can be psychological,
emotional, or physical in nature. This is called withdrawal.

concentrating, restlessness, or depression.

been taking ZYBAN for 1 week. You should set a date
to stop smoking during the second week you're taking
ZYBAN.

lot of alcohol and then suddenly stop drinking, may
