How to Use
Zyban comes as a tablet to take by mouth. It is usually taken one to three times a day and may be taken with or without food. Do not crush, chew, or divide Wellbutrin SR or Zyban tablets. Follow the d
irections on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Zyban exactly as directed.
Continue to take Zyban even if you
feel well. Do not stop taking Zyban without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will want to decrease your dose gradually. This drug
must be taken regularly for a few weeks before its full effect is felt.
