Is it safe to take Cardivas for LBBB?
Q: Is Cardivas 3.125 (one in morning, one in evening) harmful in LBBB? My father is a patient of LBBB 30%, high blood pressure and trigemnial neuralagia (V2). He has been operated for a clot in the brain (SDH) and prostrate last year. He is 75 years old. He is already taking Ramace 5 mg BD and Cardivas 3.125 (half) once in a day. One doctor wants to increase Cardivas 3.125 to two tablets and the other says this will be harmful for LBBB. Please advise.

Recently based on global experience, the treatment of high blood pressure has undergone major changes. It has been established that betablockers such as Cardivas pose an unacceptable risk of precipitating diabetes and hence should not be used, particularly in the elderly. The globally accepted guidelines are:
