I took two doses of lexapro 7 days ago and had to stop due to horrific side effects. Panic attacks, restlessness, extreme anxiety, racing thoughts, fear and dread thoughts. Since my last dose 7 days ago, some symptoms still persist such as: Anxiety, restlessness, panic. Although not as severe, it's still crippling. I've been to my own Dr and ER. Did not ever have these symptoms previously before taking it. Dr at Er just gave me one dose of Ativan and a script for cogentin. Will this end or did the medication cause damage.
