I have been on escitalopram for 8 days now and have diarrhea, nervous jittery feelings, fatigue and want to sleep in the afternoon. People on this sight have better knowledge than doctors because they have experienced the side effects and lived through it. What doIi take for diarrhea that is safe? I am a 68 year old male with high blood pressure and take carvedilol and olmesartan for that.
