depression
"Do not take this medication if you have a pre-existing anxiety disorder...even if you are on a benzo or buspirone before starting it.  My anxiety was well controlled with an SSRI and buspirone, but my depression did not seem to be getting any better.  My Psychiatrist tried switching me from the SSRI to 100 mg Wellbutrin SR.  I could only take the Wellbutrin for 6 days.  It gave me horrible panic attacks, racing heartbeat, and severe sweating.  I have no doubt it may work well for depression, but it is a bad drug to try if you have depression and generalized anxiety disorder.  I am now back on the SSRI.  I would rather deal with some depression than have panic attacks!"
