Watson Is Second Drugmaker to Pull Generic Wellbutrin

Watson is withdrawing from the market its 300 mg extended-release (ER) version of bupropion hydrochloride (HCl) after updated bioequivalence studies showed the drug is not therapeutically equivalent to its brand counterpart, Wellbutrin XL 300 mg. It’s the second generic of the antidepressant pulled from store shelves after Impax and Teva’s copycat was removed in 2012.
