I was on Cymbalta for 17 days and thought it was helping the side effects were getting better however on the 17 days I broke out in a rash from head to toe particularly bad on my throat (outside).

I am not completely sure if it was caused by the Cymbalta but stop anyway because I was out of town and not sure what else to do.

I am back in town and saw my doctor yesterday, I got medication for the rash and when it is resolved I want to try it again. I thought it was making things better and want to be really sure it was the Cymbalta that caused the allergic reaction. If I get the rash again I will have to discontinue and look for a new drug.

I would say stay on it for at least 6 months to a year, that was my plan in hopes of really clearing something up.

Good luck
