What's the difference between Wellbutrin XL and Wellbutrin SR?!
Question:
Answers:
XL is the extended release formula (releases medication over a 24 hour period). SR is the sustained release formula (releases medication over a 12 hour period).
I believe there is a generic for SR, but not XL, so SR is cheaper.
