I have been taking brand Wellbutrin XL 150 made by Valeant North America for years and the pills always had "Wellbutrin XL 150" on them -- black letters on a white pill. I just ordered the same medication from a Canadian pharmacy; the label identified it as Welbutrin XL 150, but the pill are stamped "WXL 150" -- maroon/red letters on a white pill -- and I'm wondering if I've been sent a generic pill -- or something worse (counterfeit, etc).
