Hi Carly, I havent taken Lexapro but I have heard many good things regarding it. I do know that when your taking an antidepressant it is sometimes necessary to increase or adjust the dosage to reach a good balance. I dont know what a threaputic level for Lexapro is in regards to millagrams. I would address this with your doctor especially if your have reoccuring symptoms of depression. It is always best to try to stay ahead of it before it become too bad. I am sure others will post to let you know of thier experiances with Lexapro. Please do post again and let us know how you get along.
