About a year after starting Metoprolol, my normally low blood pressure, (which initially went even lower on Metoprolol) started to climb. Cardiologist thought this was normal part of the aging process. Since it was sometimes high and sometimes not, I had the bp monitor test done and was told to monitor at home. Anyway, I thought it was weird that this was happening. Coincidentally, my appt with the specialist for osteoporosis was around this same time. Bloodwork showed my VitD levels were low. Started taking VitD religiously (1000iu to 2000iu daily). Within a few months, blood pressure back to my normal/low level and it has stayed that way.
I asked a bp specialist if there was a connection and he said there had been some small studies done showing a link.
So far no new meds needed!
