Actually, beta blockers are VERY commonly prescribed for anxiety. I've never heard of them causing anxiety. Depression, I've never heard of it either, but that doesn't mean it is not the case. Have you read about this? I just find it hard to believe, with as frequently as they are actually Rx'd to treat anxiety!
Anyway, you will hear mixed reviews on the Lexapro, as with any med. Don't put too much emphasis on any one story, everyone will differ in their reactions to a med. I personally had great success treating anxiety and depression with it for many years.
Also, there are a lot of different medications used to treat tachycardia. Have they ever tried anthing but a beta blocker? Are you being seen by a cardiologist? What causes your tachycardia?
Very best of luck to you hon. Fingers crossed that the Lexapro works for you!
I take propranolol, a beta blocker, for akathisia and anxiety. It works very well for anxiety. I think you may be having break-through depression and anxiety meaning it is working in spite of the drugs, not because of the drugs.
I agree with Annie. Any which way, the CAUSE of your symptoms isn't nearly as important as what you do to address it, and you're giving Lexapro a shot, hang in there, time will tell if it will be effective for you. Are you in therapy?
