Side Effects of Buproban: An Overview

As with any medicine, side effects are possible with Buproban® (bupropion SR). However, not everyone who takes the drug will experience side effects. In fact, most people tolerate Buproban quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
