Hi, blood pressure fluctuations can occur as you are on multiple medications. If it drops you may have postural hypotension. The recommended goal for systolic pressure is less than 140 mm Hg. While adjusting the dosage of medications for this, your diastolic pressure should not be reduced to less than 70 mm Hg in trying to reach your target systolic pressure. You can try lifestyle changes like don't add additional salt in your diet, exercise regularly and practice relaxation techniques to lower your stress levels. And see if this helps. Regards.
