I have been monitoring my bp at home with an mercury sphgmomonometer. i have been consistantly getting resdings 106/64 for several years. i feel that at my age (83)this is a little low and have been thinking about reducing the dosages.for about 10 years my bp meds have been: nadolol 80 mg--nifedipine 30 mg,i realize that the nadolol tablets can be cut in half ( i get 40 mg tabs.) but the nifedipine can not be reduced. perhaps a gradual reduction in nadolol would be sufficient to raise my bp to a more satisfactory level. please advise, bigreach
