Suffering From Hypertension, Chronic Interstitial Nephritis And Left Posterior Bundle Branch Block. On Envas And Anxit. Continue?

Hi, I am 50 yrs old and suffering from Hypertension, Chronic Interstitial Nephritis and left posterior bundle branch block problem as per ECG. My pressure was not getting controlled with Envas 5 mg BD and Atenolol50 OD and also had elevated cholesterol and feeling anxity. So my doctor prescribed me Tab. Amlopress 5 mg OD, Atrovas, asprin 5 mg OD and Anxit 2.5 mg BD. I have been taking Anxit 2.5 mg BD since more than one year. Though by and large I am not facing any problem except sometimes a feeling of some anxity some times. My question is continuing Anxit for so long, will it cause any problem to me ????
