Zyban

What is the most important information I should know about Zyban?

• While you are taking Zyban you may need to be monitored for worsening symptoms of depression and/or suicidal thoughts at the start of therapy or when doses are changed. This concern about the increased risk of suicidal thoughts or behaviors may be greater if you are 18 years of age or younger and are taking Zyban. In patients younger than 18 years, the period of risk may extend beyond start of therapy or when doses are changed. Your doctor may want you to monitor for the following symptoms: anxiety, panic attacks, difficulty sleeping, irritability, hostility, impulsivity, severe restlessness, and mania (mental and/or physical hyperactivity). These symptoms may be associated with the development of worsening symptoms of depression and/or suicidal thoughts or actions. Contact your healthcare provider if you develop any new or worsening mental health symptoms during treatment with Zyban. Do not stop taking Zyban.
• Do not stop taking Zyban without first talking to your doctor. It may be several weeks before you begin to feel better, and you may require continuous treatment for quite some time.
• Avoid alcohol or drink it only in moderation while taking Zyban. Alcohol may increase the risk of having a seizure while taking Zyban. However, if you usually drink a lot of alcohol, talk with your doctor before stopping. Suddenly stopping may increase the risk of having a seizure. Talk to your doctor about alcohol use before starting treatment with Zyban.
• Do not crush, chew, or break the sustained- or extended-release tablets (Wellbutrin SR, Wellbutrin XL, Zyban SR). Swallow them whole. They are specially formulated to release slowly in the body. If you are unsure of the formulation of your medication, ask your healthcare provider.
• Zyban may be used to treat different medical conditions. You should not be taking more than one product containing Zyban at a time (e.g., Wellbutrin and Zyban SR). Talk to your doctor if a second product containing Zyban is prescribed for you. Too much of this medicine can increase the risk of a seizure.
• Never take more Zyban in one dose or in one day than is directed by your doctor. Higher doses of Zyban may increase the risk of a seizure.

How should I take Zyban?

• Take Zyban exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
• Take each dose with a full glass of water.
• Zyban can be taken with or without food.

  · No single dose of the regular-release product Wellbutrin should be more than 150 mg, and doses should be taken at least 6 hours apart with a maximum daily dose of 450 mg.

• If you are taking Zyban SR to help you stop smoking, a target "quit date" is usually set for the second week of treatment with Zyban SR. Although it is not physically harmful to smoke while taking Zyban SR, continuing to smoke after the date you set to stop smoking will seriously reduce your chance of breaking the smoking habit.
• Nicotine replacement products (patches or gum) can be used during treatment with Zyban SR under the supervision of a doctor. Zyban SR and a nicotine replacement product together may raise blood pressure and your doctor may want to check your blood pressure regularly. Do not smoke at any time if you are using a nicotine product along with Zyban SR as this can cause serious side effects from too much nicotine.
• The WELLBUTRIN XL tablet is covered by a shell that slowly releases the medicine inside the body. You may notice something in the stool that looks like a tablet. This is normal. This is the empty shell passing from the body.
