There are no documented drug interaction between cabergoline and bupropion (
Wellbutrin). However, it does not mean it is safe to take cabergoline,
bupropion, and riluzole all together.
From the previous post, I know you are taking riluzole (Rilutek) for treating "treatment-refractory obsessive-compulsive disorder". However, I do not know why you are taking cabergoline, in addition to wanting to ask your physician to prescribe bupropion.
