What do you suggest if I have had OCD really bad in the past, and Prozac (fluoxetine) helped, so my doctor tells me I need to keep taking prozac (fluoxetine).?

Your Dr probably. assumes that the OCD is still present and being kept at bay by the Prozac (fluoxetine). Therefore he wants to leave well enough alone. Have you been in psychotherapy and learned any new coping skills to counteract the OCD? If not I'd agree with your Dr. If U have learned new ways 2stop obsessing and want 2see if they R adequate talk to him about how 2do a trial off the medication & follow his instructions.
