You should not take Wellbutrin SR if you have seizures or an eating disorder, or if you have suddenly stopped using alcohol, seizure medication, or sedatives. If you take Wellbutrin for depression, do not also take Zyban to quit smoking.

How should I take Wellbutrin SR?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed. Too much of this medicine can increase your risk of a seizure.

If you take Zyban to help you stop smoking, you may continue to smoke for about 1 week after you start the medicine. Set a date to quit smoking during the first 2 weeks of treatment. Talk to your doctor if you have trouble quitting after taking Zyban for 7 to 12 weeks.
Your doctor may prescribe a nicotine replacement product (such as patches or gum) to help you stop smoking. Start using the nicotine replacement product on the same day you stop (quit) smoking or using tobacco products.
Some people taking Wellbutrin SR (Wellbutrin or Zyban) have had high blood pressure that is severe, especially when also using a nicotine replacement product (patch or gum). Your blood pressure may need to be checked before and during treatment with this medicine.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
You may have nicotine withdrawal symptoms when you stop smoking, including: increased appetite, weight gain, trouble sleeping, trouble concentrating, slower heart rate, having the urge to smoke, and feeling anxious, restless, depressed, angry, frustrated, or irritated. These symptoms may occur with or without using medication such as Zyban.
