What's the difference between Wellbutrin and Wellbutrin SR?

Wellbutrin is an immediate release tablet whereas Wellbutrin SR is a slow release tablet. All this means is that Wellbutrin SR is released over a 3 hour period whereas regular Wellbutrin is released immediately.

Wellbutrin SR is more expensive because of this. You should choose the one you have been advised, or, if unsure should try Wellbutrin in small doses (See Wellbutrin Dosage) and consult your doctor for long term advice.
