I agree with the above reply, with the exception of the info that propanolol needs to be taken daily. Beta blockers like Inderal are often prescribed "as needed" to combat stage fright
, presentation anxiety. They're usually prescribed to be taken within a certain time frame (usually an hour or so) before the anxiety causing event.
I do agree that taking both medications isn't necessary, and could exacerbate symptoms of drowsiness, dizziness, etc.
