These days beta blockers are not the drug of choice for high blood pressure (there are exceptions). The drugs of choice are ACE inhibiters, starting with
Lisinopril and if that has side effects, (usually coughing) go to Losartan. Before starting any blood pressure meds a doctor should try calcium, D3 and magnesium supplements, which will satisfactorily resolve blood pressure issues in 15-20 percent of patients, with moderate exercise and simple dietary restrictions.
