I become dizzy after climbing a flight of stairs- no breathing problems. 31- aspirin cymbalta (duloxetine) daily. Onset 4 months after starting cymbalta (duloxetine)?

Cymbalta (duloxetine) Onset of symptoms not matching possibility that Cymbalta (duloxetine) is the cause, unless dose was recently adjusted. Consult your doctor for workup to explore other possibilities.
