My physician has increased my Lexapro from 20 mg to 20 mg 3x day and increased my Pristq 50 mg to 100 mg a day. Does anyone know the recommeded safe doses for Lexapro??? I was diagnosed with Bipolar Disorder and now my physician tells me I have Bipolar Depression not Bipolar Disorder. I AM VERY CONFUSED NOW. Any information you can give would be very much appreciated.
