I just started taking cymbalta for depression, switching over from remeron. Over a period of two weeks, I gradually decreased my Remeron dose. Yesterday I stopped remeron and began cymbalta. I have had a loose stool, not to the point of diahrea, but unusual for me the past two days. Is this a possible side effect of the switch to cymbalta? I imagine even if it is and doesn t progres to diahrea its probably ok, When should I expect it to go away? It s not causing discomfort or inconvenience, its just that its not typical.
