Hi, may I answer your health queries right now ?  Please type your query here...I am monitoring my bp from home.  I am currently getting two different readings.  First reading is 140/74. Second reading (2 minutes later) is 116/74.  Im taking 5 mg of lisinopril daily.  My concern
Hello, Lisinopril does decrease BP, but this much fall within minutes is unlikely. Either of two readings is false. You should take the third reading in order confirm which is one is right. 5-10 MMH variation is acceptable. Also, if you bent or tighten the arm or doing some activity with hand during may affect the readings. So this is fallacy of electronic apparatus, we need to take multiple readings. Hope this helps you and get back if you have any doubts.
