Interseting.... anyway ive been given propanolol for panic attacks, from a friend who insisted. Now im beginning stages of psnic, heart racing. I do not have good doctors i can talk to as i please. Medical facilities largely ignore me when i ask for help. So can i take this propanolol to help my hear eacing and stop and stop a psnic attack? What are the risks if i take this? As my panic attacks are not being treated, canabis, benadryl, and zofran have been used to combat anxiety and its physical effects.
