t have any panic attacks at all when I was on it, and no depression. The
side-
effects were very mild for me (compared to the
side-
effects I had with Prozac), and they only lasted a week or two. I stopped the Lexapro about 6 months ago because I really felt like I didn't need it. Then about 5 weeks ago I had a nervous breakdown (depression and panic), so I'm back on the Lexapro. I noticed a difference in 2-3 weeks, but the full effect can take up to 3 months to be felt.
