I switched from the small round white generic Wellbutrin to the large round yellow Wellbutrin 2 weeks ago. Not to my agreement, I just picked it up at the pharmacy and there it was. Anyway, today I went to the doctors for a rash and she told me that different manufacturers have different fillers in the pills, so I could be allergic to one of the components. I took my new Wellbutrin back to the pharmacy and the pharmacist gave me my old generic brand. The rash was on my stomach, the hips, my back...and it appeared Sunday night. Just a story in case anyone is experiencing something similar. If this doesn't make my rash go away, I will report back to let you know it in fact wasn't the change. ****** pic of the different pills. ****** pic of my rash
