<s>[INST] I am 76, ht 5ft 5 in, weight 150 lbs.  I take Diovan 80 once a day.  Lately I feel very tired in the PM and started monitoring my BP.  Today i took one-half of my pill and now, at 1:30 my BP is 108/83 , pulse 59.  Should I be worried?  Should I contact my Dr.? [/INST] Hiyou were on a dose of 80 mg Alsatian and you were feeling week even on halving the tablet your blood pressure is still on the lower side while taking any hypertensive medication you should keep a record of your blood pressure every week and should visit your doctor every two months, because on the basis of the blood pressure records doctor is going to taper the dose of the blood pressure medicine you are ones of now your weakness is most likely because of the overdose of divans make the doses half and check your BP twice a day and try to taper it to a dose where your BP is 120/80 .yes you can plan a visit to doctor </s>
