Monitor BP for 3 days twice a day... if more than 140/90 despite medication, we may have to change either dose or drug. If BP is less then needs to evaluated and decided if medication needs careful tapering or not. Also watch for diarrhea/dehydration- in such cases BP may drop but later on u will need to continue.

Initial fluctuations are expected after a change in medication .. but u r now on a better drug, can continue it .... Have self monitoring always to better understand the effects of medication...

You have to check BP and maintain a chart for one week. After that dose will be fixed
