Long ago, when I first started taking Wellbutrin, I took one 150mg SR tab for a week then went up to 300mg (twice a day, 8 hours apart) and didn't have any allergic reactions to it.
I eventually stopped taking it because I didn't want to be dependent, but it seems like I can't function without the help of antidepressants.
I moved to a new place since then, so I found a new hospital but they only had XL. Just like the first time, I upped the dose to 300mg after a week and on the 2nd and 3rd day, my entire body started itching like crazy at night and my shoulder, neck, face(even my ears!) broke out in hives. It was horrible. I immediately stopped taking it and the hives were completely gone the next morning never to be seen again.
The SR ones I took long ago are generic but XL ones are brand name. But I don't think the brand is the cause.
Any insight would be nice. Thanks.
