hello doc, My mother,55 has been a hypertensive from the past 12-13 yrs.She was started on amlodipine 2.5 and she did fine for 3-4yrs when she started having acute cough.Amlodipine was changed to Nifedipine and the cough subsided.For another 3-4yrs she was doing well when her legs started becoming edematous.Nifedipine was then changed to hydrochlorthiazide and her BP has been perfect until the past 6 months when it shot to 145/90.Inspite of increasing the dose there was no difference so she was kept on telmisartan40mg+hydrochlorthiazide.Even now the BP does not seem to come down and it shows a value of around 145/90.She does not have any other complaints (except for urinary incntinence for which she has not yet started any medication),her heart and kidney profiles hav also come out clear.Can u suggest a gud combination and is the BP at an alarming level? thank you
