<s>[INST] 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. [/INST] Hello Welcome to Ask a Doctor service I have reviewed your query and here is my advice.Your blood pressure seems to be in control if you are taking the drugs, if you are going to measure the blood every on and often so it will show different reading every time it will confuse you and may create panic too, so better to see the physician and discuss this  and let the physician read the blood pressure. in absence of clinical symptoms it is nothing to worry.Hope I have answered your query, let me know for further assistance. </s>
