Bupropion (Wellbutrin SR)

Overview

Bupropion is a prescription medicine. It also is a treatment for depression. A sustained-release form of bupropion is approved to help people stop smoking.

Experts think that bupropion lessens tobacco cravings and withdrawal symptoms by boosting the levels of certain brain chemicals.

It takes days for bupropion to build up in the blood and start working. You typically start taking bupropion a week or two before you quit smoking.
