An order for Wellbutrin SR can be confused with Wellbutrin XL. Both drugs are norepinephrine and dopamine reuptake inhibitors used to treat depression. But Wellbutrin SR is a slow-release form of the drug given twice a day, whereas Wellbutrin XL is an extended-release form of the drug given once a day. Because of their absorption and differences in onset of action, these drugs are not interchangeable.
