No symptoms, mild pedal edema. *Earlier was on 1 tab TelmisartanH (ARB) and bp was well controlled. Hepatologist changed it to Carvedilol 3.125 mg 1-0-1 (betablocker) to aid in cirrhosis.  BP lowers after taking medicine but remains on higher side. Not as controlled as earlier medicine.

Please suggest if dose needs to be increased or old medicine can be added with current one?? 2) If anyday bp is 150/90 or more even after taking medicine, can she take 1 more tablet ??
