I just got prescribed 20mg of propranolol for my panic attacks. I’m scared to take it because I don’t want it to make them worse or cause my heart to feel weird. I have normal BP 117/72 is my normal. I’ve heard this med can cause dizzy and make it hard to breathe in which will make my panic attack worse. Does it work for panic attacks? Mine are the kind that make me faint sometimes and shake and make it hard to breathe
