Is the medication novac only? or is it norvasc
which contains amlodipine
. I am not able to find out this drug Novac. However if the dose of a blood pressure lowering agent is increased and the patient develops light-headedness and disorientation
but BP is still 150/90 mmHg, I would recommend to check for postural fall in BP and would most likely need alteration in the timings of medications. If the rpoblem still persists drug may have to be withdrawn. Please see your GP for this issue.
