About stage fright: Can beta blockers reduce the symptoms of shortness of breath and choking voice that can occur at the beginning of a speech? Thanks

Yes, but. Yes, but everyone responds to all medicines in their own unique way. To make matters even more complicated, beta blockers come in many versions and strengths. For stage fright, you need one that can readily cross the blood brain barrier. Propranolol is the best. One usually starts with 10 mg 1-2 hrs beforehand and if that's not effective, the dose can be upped to 20 or 40 mg.
