Have bad health anxiety - been on 40mg prozac (fluoxetine) for a year. My anxiety seems to be worsening - is it ok to go to 60mg? Are there any side effects?

Therapy? Have you yet tried any form of psychotherapy? Typically, the optimal combination of things to treat emotional issues such as anxiety or depression is medication (which, on your best day, is supposed to take the edge off symptoms) but the real gruntwork takes place in psychotherapist's consulting room.
