I have noticed that the emergence of hives is typically found in Wellbutrin users DURING treatment. I however stopped Wellbutrin due to its lack of efficacy. I have social anxiety/ADHD and I am a smoker. I was instructed to revert back to Zoloft and started breaking out in hives in my hands, behind my knees, abdomen, and behind my neck/ear area. I have been taking Wellbutrin for over a month. Are my symptoms a result of the abrupt stop of th medication?
