dear , i have read your query, yes ur blood pressure would have fallen down due to BENZAPRIL. but before that we have to exclude some points- 1 . fasting or skipping of last meal or u had any salt free diet - as this will decrease your b.p and if u take medicine on this situation then your b.p will go below the normal physiological value 2.r u taking any other medicine . if yes ,then pls mail me back. as certain medicines increases the time of your medicines in blood and increases the efficiacy of drugs. * INCREASED URINATION OR BOWL FREQUENCY INCREASED 3 LOW water consumption , low diet( pls mail me your average diet intake data) 4 overwork load, and altered sleeping time . IF NONE OF THE ABOVE CAUSES ARE PRESENT THEN U CAN IMMEDIATELY COME DOWN TO SINGLE DOSE OF YOUR MEDICINE AFTER BREAKFAST ONLY . MEASURE YOUR B.P IN EVENING AFTER 6 PM , IF IT REMAINS BELOW 140/90 AND WITHOUT ANY SYMPTOMS FOR 7 DAYS THEN U CAN CONTINUE ON A SINGLE DOSE AFTER BRKFAST. TAKE PROPER DIET AND DONT SKIP MEALS, START YOGA . HOPE THIS WILL HELP U, IF U THINK ANYTHING ELSE TO TELL THEN PLS COME BACK TO ME,I WILL BE HAPPY TO HELP U,,,,THANKS FOR UR QUERY INSTEAD OF STOPPING BENZAPRIL ALONE , ONE TIME COMBINATION IS PREFERRED AS BENZAPRIL IS BETTER TOLERATED IN UR AGE GROUP AND PREVENT ILL CHANGES IN CARDIOVASCULAR SYSTEM DUE TO HYPERTENSION, GOOD WISHES
