question: Morning! I'm Romualdo, 54. I'm from Brazil. I am hypertense and take propanolol 40mg and clorthalidone 12,5mg simultaneouly 2X a day for five years now. Happens I need to pay a visit to dentist in order to make a tooth extraction. But, I have been told by pals that I coundn't use beta blockers and vessel constrictors as local anesthesia, and told I can only take felipressin at 2%. Is that correct? Thank you for your help.
