<s>[INST] Hi, may I answer your health queries right now ?  Please type your query here...  I just began a lisinopril and hydrochiorothiazide pill yesterday for high bloodpressure.  I just did my pressure here at home and it reads 116/72.  Is it normal to be that low? [/INST] Single measures should not prompt concern. Decisions are best made from an average value from a two week span. Too low means that you have symptoms of fatigue or light headedness. Your target depends on other illnesses that you may have but in general is a two week average blood pressure systolic <150 and diastolic <85. </s>
