Hi, I was recently prescribed 10 mg Lexapro for depression and OCD having been on Prozac for a number of years. As advised by my doctor I tapered the Prozac and then waited 5 days before starting the Lexapro. The first few days it seemed to be working well, but then I started to develop very strong heart palpitations that kept me up at night. These palpitations continued to get worse until they got so bad that I had to quit taking the Lexapro and go back on the Prozac. My question is - do you think I quit the Lexapro too soon? Is there a chance the palpitations would have gone away if I had waited a little longer? I ask because I found Lexapro quite effective in controlling my symptoms and would have liked to stay on it if only the side effects hadn't been so bad.
