I have been taking Wellbutrin SR 200 mg tablets twice a day for at least 6 years. I have just recently started having issues with urination. I feel as if I need to urinate immediately, all the time. Like if I don't get to the bathroom I'm just going to go, that hasn't happened. Yet when I do get to the bathroom I can not urinate. Could this be caused by the extended use of the Wellbutrin?
