I have Cymbalta, (duloxetine) Wellbutrin and celexa combo. Is it harmful? Fibro and depression

I'd be concerned. Definitely discuss the combination w/ your Dr - ALL three are risky in combo w/ the others. On top of serotonin syndrome, the Wellbutrin (bupropion) in combo can cause seizures and other bad things. If needed, the risk may be necessary but if there are options, this is not a good one. Ask yourself, are you satisfied? A therapist might help you think it through.
