You may experience some or none of the bupropion side effects explained in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried. Therefore, make sure to let your healthcare provider know if you develop any side effects while taking bupropion. Also let your healthcare provider know if you develop something that "just does not seem right" during treatment with this medicine. While it may not be a side effect of bupropion, your healthcare provider will be able to diagnose and treat the problem.
