Bupropion (patient information)

IMPORTANT WARNING:

For people taking bupropion (Zyban) to stop smoking

• Some people have reported symptoms such as changes in behavior, hostility, agitation, depressed mood, and suicidal thoughts (thinking about harming or killing oneself or planning or trying to do so) while taking bupropion to stop smoking. The role of bupropion in causing these mood changes is unclear since people who quit smoking with or without medication may experience changes in their mental health due to nicotine withdrawal. However, some of these symptoms occurred in people who were taking bupropion and continued to smoke. Some people had these symptoms when they began taking bupropion, and others developed them after several weeks of treatment or after stopping bupropion. These symptoms have occurred in people without a history of mental illness and have worsened in people who already had a mental illness. Tell your doctor if you have or have ever had depression, bipolar disorder (mood that changes from depressed to abnormally excited), schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions), or other mental illnesses.
• If you experience any of the following symptoms, stop taking bupropion (Zyban) and call your doctor immediately: suicidal thoughts or actions; new or worsening depression, anxiety, or panic attacks; agitation; restlessness; angry or violent behavior; acting dangerously; mania (frenzied, abnormally excited or irritated mood); abnormal thoughts or sensations; hallucinations (seeing things or hearing voices that do not exist); feeling that people are against you; feeling confused; or any other sudden or unusual changes in behavior. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own. Your doctor will monitor you closely until your symptoms get better.

For people taking bupropion (Wellbutrin) for depression

• A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as bupropion during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. This risk should be considered and compared with the potential benefit in the treatment of depression, in deciding whether a child or teenager should take an antidepressant. Children younger than 18 years of age should not normally take bupropion, but in some cases, a doctor may decide that bupropion is the best medication to treat a child's condition.
• No matter what your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases the risk that you will become suicidal, especially at the beginning of your treatment or any time that your dose is increased or decreased. This risk is higher if you or anyone in your family has or has ever had bipolar disorder or mania or has thought about or attempted suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.
• You should know that your mental health may change in unexpected ways when you take bupropion or other antidepressants even if you are an adult over age 24 or if you do not have a mental illness and you are taking bupropion to treat a different type of condition. You may become suicidal, especially at the beginning of your treatment and any time that your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.

For all patients taking bupropion

• Your health care provider will want to see you often while you are taking bupropion, especially at the beginning of your treatment. Be sure to keep all appointments or office visits with your doctor.
• Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with bupropion and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can visit the Food and Drug Administration (FDA) website: http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm or the manufacturer's website to obtain the Medication Guide.
• Talk to your doctor about the risks and benefits of taking bupropion.

Why is this medication prescribed?

• Bupropion (Aplenzin, Wellbutrin, Wellbutrin SR, Wellbutrin XL) is used to treat depression. Bupropion (Aplenzin, Wellbutrin XL) is also used to treat seasonal affective disorder (SAD; episodes of depression that occur in the fall and winter each year). Bupropion (Zyban) is used to help people stop smoking. Bupropion is in a class of medications called antidepressants. It works by increasing certain types of activity in the brain.

How should this medicine be used?

• Bupropion comes as a tablet and a sustained-release or extended-release (long-acting) tablet to take by mouth. The regular tablet (Wellbutrin) is usually taken three times a day, with doses at least 6 hours apart, or four times a day, with doses at least 4 hours apart. The sustained-release tablet (Wellbutrin SR, Zyban) is usually taken twice a day, with doses at least 8 hours apart. The extended-release tablet (Aplenzin, Wellbutrin XL) is usually taken once daily in the morning; doses of the extended-release tablet should be taken at least 24 hours apart. When bupropion is used to treat seasonal affective disorder, it is usually taken once a day in the morning beginning in the early fall, continuing through the winter, and stopping in the early spring. Sometimes a lower dose of bupropion is taken for 2 weeks before the medication is stopped. Take bupropion with food if the medication upsets your stomach. If you have trouble falling asleep or staying asleep, do not take bupropion too close to bedtime. Take bupropion at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take bupropion exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
• Swallow the sustained-release and extended-release tablets whole; do not split, chew, or crush them.
• Your doctor will probably start you on a low dose of bupropion and gradually increase your dose.
• It may take 4 weeks or longer before you feel the full benefit of bupropion. Continue to take bupropion even if you feel well. Do not stop taking bupropion without talking to your doctor. Your doctor may decrease your dose gradually.

Other uses for this medicine

• Bupropion is also sometimes used to treat episodes of depression in patients with bipolar disorder (manic depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods) and to treat attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age). Talk to your doctor about the possible risks of using this medication for your condition.
• This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Also tell your doctor if you drink large amounts of alcohol but expect to suddenly stop drinking or you take sedatives but expect to suddenly stop taking them.
