My primary physician is off today. So I can t ask, but I m on 20mg lexapro. It s it ok to double my dose, because my depression is hitting me extra hard recently, and panic attacks are becoming more frequent. For example my heart rate is jumping to 140bpm, and I feel like I can t breathe. I should also add, I can t afford the subscription to this site right now, so I won t even receive an answer?
