Important safety information:

• Bupron SR may cause drowsiness, dizziness, or blurred vision. These effects may be worse if you take it with alcohol or certain medicines. Use Bupron SR with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
• Check with your doctor before you drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are taking Bupron SR; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
• Bupron SR may increase your risk of seizures. Your risk may be greater if you also have certain medical conditions, use certain medicines, or if you use a lot of alcohol. Talk to your doctor to see if you may have a greater risk of seizures while taking Bupron SR.
• If you already drink alcohol or use sedatives, do not suddenly stop them without first checking with your doctor. Suddenly stopping them may increase your seizure risk.
• Do not take decongestants (eg, pseudoephedrine), stimulants, or diet pills while you are taking Bupron SR without first checking with your doctor. They may increase your risk of seizures.
• The risk of seizures may be greater if you take Bupron SR in high doses or for a long time. Do NOT take more than the recommended dose, change your dose, or use Bupron SR for longer than prescribed without checking with your doctor.
• Children, teenagers, and young adults who take Bupron SR may be at increased risk for suicidal thoughts or actions. Watch all patients who take Bupron SR closely. Contact the doctor at once if new, worsened, or sudden symptoms such as depressed mood; anxious, restless, or irritable behavior; panic attacks; or any unusual change in mood or behavior occur. Contact the doctor right away if any signs of suicidal thoughts or actions occur.
• If you have trouble sleeping, you may be taking your dose too close to bedtime. Talk with your doctor about changing your dosing schedule.
• Bupron SR contains the same ingredients as Zyban, a medicine used to help stop smoking, and Aplenzin, another medicine used to treat depression. Do not take Bupron SR if you are also taking Zyban or Aplenzin. Discuss any questions or concerns with your doctor.
• Use Bupron SR with caution in the elderly; they may be more sensitive to its effects.
• Bupron SR should be used with extreme caution in children; safety and effectiveness in children have not been confirmed.
