Zyban (Bupropion Hydrochloride sustained-release tablets, or Bupropion SR) is a prescription medication that is used to help people quit smoking (source). Bupropion belongs to the family of medications known as norepinephrine and dopamine reuptake inhibitor (NDRI) antidepressants. It works by reducing your nicotine withdrawal symptoms (e.g., irritability, anxiety, restlessness) and your smoking urges. It is not the same as nicotine replacement treatments; instead, it is thought to act in the brain to decrease cravings. Quitting smoking reduces your risk of heart and lung disease as well as cancer.

This medicine should be used with a patient support program. Please consult your doctor for personalized advice and take your medication exactly as prescribed by your doctor, or refer to the medication guide.
