Hi, KentuckyFan, and welcome! Well, Cymbalta and Prozac are similar and are both used for depression. But obviously they are used for other things, too. Both help raise the serotonin levels I believe but I haven't heard of it being used for fibro. But I'm so happy this drug has helped you.
My husband was put on Prozac for severe depression and it was wonderful for him, too.
