earlier myself was consuming BETACARD-25. to lower my blood pressure. Since last 10 years this was the medcine. recenly my blood pressre recorded 165/97. then docor changed the tab and now I am taking TELSARTAN 80.But first day i was not comfortable for this. Then myself changed to 40 mg along with hlf tab of Betacard-25mg as told by my doct.Is it ok
