hi, there christina86, I too have just gone on Luvox for obsessive thoughts, but am not officially diagnosed with OCD. I've been on it for two weeks, and at first I didn't notice any difference, but now I think it is helping. I have noticed headaches and ringing in my ears. my pdoc didn't want me on too much antidepressant so he halved my Effexor at the same tome. that could be causing the headaches. I have heard that it takes many weeks to determine if Luvox is working, so hang in there and be patient, and let us know how u are doing.
