The first couple years of taking Lexapro I had no side effects. For the last year +, I have had abdominal pain, gas, heartburn & diarrhea almost daily. I have asked my Dr. 3xs if it could be from the Lexapro, but he keeps telling me no. I have a decent diet ~I eat lots of fruit & salad & drink nothing but water. My Dr. just want to give me more med's for the symptoms (prilosec, etc). I take Pepcid and GasX almost every day. To test my Lexapro theory I went off it for three days (I know your not supposed to just stop, but I am at my wits end and really wanted to see if this is the problem). The first day my sypmtoms were the same. The second day they were slightly better and the third day there was no heartburn at all. I plan on telling my Doc, but I know he will just tell me that it is not related. Has anyone else had these side effects from Lex? Anyone been on Lex for awile with no side effects, only to have them develop later? Don't side effects happen in the beginning only?
