I'm 56 y/o with hx of MVP,SVT and was on Inderal for 23 yrs. until after taking RED BULL energy drink threw me to AFIB that sent me to ER and got admitted overnight ,that problem got resolved until about few months ago i started having on and off palpitations again and my doctor put me on 50mg METOPROLOL and take extra dose for frequent palpitations but i noticed that the more i take METOPROLOL the worst my symptoms gets with some dizziness, sleepless nights ,occasional chest pains,joint pains so i went to my doctor again ,had stress test, 24 hr. monitor, and everything was normal, i was then referred to a Cardiologist-Electrophysiologist who told me i was taking to much Metoprolol that i should cut it to 25mg , He planned to put me on 30 day holter monitor to see the activity of my heart but on the other hand being a nurse i tried to monitor myself, i still have the same symptoms but less since i cut down my dose but i decided to stop the Metoptolol completly and put myself back on Inderal for about a week now i'm telling you it was alike a night and day symptoms of increasing palpitations are less and i feel much better , hopefully i treated myself and goodbye Metoprolol.
