I am contemplating going back on fluoxetine after being off of it for a little over a year. When I went off Fluox (40mg) I started taking Lexapro (escitalopram 20mg). Just wondering about side effects and effectiveness when starting back up. I experienced some side effects for the first couple of weeks when I began the fluoxetine. I was on Fluox for about 5 years before I switched... I made the switch because it seemed to lose its effect for me. I stopped taking the Lexapro because I didn't like it. I had too many side effects. I have been off medicines for almost 4 months but I am beginning to feel my depression setting back in...
