I saw Dr. Black at the Hunter Hopkins Center and miserably failed the Tilt Table Test. I have always had low BP (systolic under 100) and a systolic BP in the 80's with infections....but never had tachycardia. Over the past several months my heart rate is in the 120's with the simplest of things, eating a meal, taking a barely warm bath etc. I just received Droxidopa in the mail and read all the literature but wanted to hear any considerations from folks who have taken it. Thanks!
