I was prescribed lexapro as I suffer from panic attacks. I have no form of depression. I took the 10mg at 11:15 am yesterday andI felt awfully nauseous an hour after. Today I feel like it has made me depressed. I have not taken another dose as it quite frankly scares me. How one tablet can affect my head and body so much. I feel like im outside my own body I have that little emotion. is it safe to stop? Surely one dose can not have a terrible long term effect?
