i have high blood pressure controlled by medication however due to weight loss, my pressure was consistently at lower levels so my dr. instructed me to monitor it and if it went above 140, to take 1/2 dosage. BP good the last few days but today, early morning reading was 143/76 so I took 1/2 pill; at 2pm, BP reading was 150/86 and one hour later 151/87, I took the other 1/2 of pill. I ve called dr office but no response yet? what do you suggest? Tx.
