Generic Name: bupropion (Oral route)
Suicidality and Antidepressant Drugs
Use in Treating Psychiatric Disorders: Although Zyban(R) is not indicated for treatment of depression, it contains the same active ingredient as the antidepressant medications Wellbutrin(R), Wellbutrin SR(R), and Wellbutrin XL(R). Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of bupropion or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Bupropion is not approved for use in pediatric patients.
Use in Smoking Cessation Treatment: Wellbutrin(R), Wellbutrin SR(R), and Wellbutrin XL(R) are not approved for smoking cessation treatment, but bupropion under the name Zyban(R) is approved for this use. Serious neuropsychiatric events, including but not limited to depression, suicidal ideation, suicide attempt, and completed suicide have been reported in patients taking bupropion for smoking cessation. Some cases may have been complicated by the symptoms of nicotine withdrawal in patients who stopped smoking. Depressed mood may be a symptom of nicotine withdrawal. Depression, rarely including suicidal ideation, has been reported in smokers undergoing a smoking cessation attempt without medication. However, some of these symptoms have occurred in patients taking bupropion who continued to smoke.
All patients being treated with bupropion for smoking cessation treatment should be observed for neuropsychiatric symptoms including changes in behavior, hostility, agitation, depressed mood, and suicide-related events, including ideation, behavior, and attempted suicide. These symptoms, as well as worsening of pre-existing psychiatric illness and completed suicide have been reported in some patients attempting to quit smoking while taking bupropion in the postmarketing experience. When symptoms were reported, most were during treatment with bupropion, but some were following discontinuation of treatment with bupropion.
These events have occurred in patients with and without pre-existing psychiatric disease; some have experienced worsening of their psychiatric illnesses. Patients with serious psychiatric illness such as schizophrenia, bipolar disorder, and major depressive disorder did not participate in the premarketing studies of bupropion.
Advise patients and caregivers that the patient using bupropion for smoking cessation should stop taking bupropion and contact a healthcare provider immediately if agitation, hostility, depressed mood, or changes in thinking or behavior that are not typical for the patient are observed, or if the patient develops suicidal ideation or suicidal behavior. In many postmarketing cases, resolution of symptoms after discontinuation of bupropion was reported, although in some cases the symptoms persisted; therefore, ongoing monitoring and supportive care should be provided until symptoms resolve.
The risks of using bupropion for smoking cessation should be weighed against the benefits of its use. Bupropion has been demonstrated to increase the likelihood of abstinence from smoking for as long as 6 months compared to treatment with placebo. The health benefits of quitting smoking are immediate and substantial .
Wellbutrin(R): Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. This risk must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Not approved for use in pediatric patients.
Zyban(R): Serious neuropsychiatric events, including depression, suicidal ideation, suicide attempt, and completed suicide, have been reported in patients with and without pre-existing psychiatric disease who were taking bupropion for smoking cessation; some experienced worsening of their psychiatric illnesses. All patients should be observed for changes in behavior, hostility, agitation, depressed mood, and suicide-related events, including ideation, behavior, and attempted suicide. The patient should stop taking bupropion and contact a healthcare provider immediately if any neuropsychiatric behavior that is not typical for the patient is observed, or if the patient develops suicidal ideation or suicidal behavior. This risk should be weighed against the benefits of its use.

Bupropion is used to treat mental depression. It is also used as part of a support program to help people stop smoking. This medicine may also be used to prevent depression in patients with seasonal affective disorder, which is sometimes called winter depression.
Bupropion is sold under different brand names for different uses. If you are already taking medicine for mental depression or to help you stop smoking, discuss this with your doctor before taking bupropion. It is very important that you receive only one prescription for bupropion at a time.
This medicine is available only with your doctor's prescription.
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of bupropion in the pediatric population. Studies with other medicines used for depression have shown that some children, teenagers, and young adults think about suicide or attempt suicide when taking these medicines. Because of this toxicity, use in children is not recommended.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of bupropion in the elderly. However, elderly patients may be more sensitive to the effects of this medicine than younger adults, and are more likely to have age-related kidney or liver problems, which may require caution and an adjustment in the dose for patients receiving bupropion.
