I have had OCD for a long time in my life. I have been on Lexapro for about 2 years now. I have recently been on 40 mg of Lexapro and have felt alright but not my full potential. My Dr. put me on 60 mg of Lexapro to see if this helps. I have had no side effects from this drug and that's why she is willing to go so high. My question is since I have been on this drug for about 2 years, how long will it take after upping the dosage for me to see an improvement????
