I just started 5 mg Lexapro 2 days ago and I'm still experiencing anxiety. I was prescribed Lexapro because my doctor switched me from brand name birth control to generic in August, and I'm still feeling the terrible side effects (even after switching back to my brand name birth control). I'm experiencing racing, intrusive thoughts, panic attacks, feelings of guilt, social anxiety..and so on. Before she prescribed me the generic birth control I was as happy as can be, and I just have these terrible feelings I'm going to lose my boyfriend of 3 years over this. I was wondering when this medicine will begin to work and if anyone has the same experience. Thanks!
