I take two medications for my high blood pressure (Primary Hyperaldosteronism, Secondary Hypertension) - hydrochlorothiazide 25 mg and spironolactone 25 mg daily. I've had two occurrence of PMR and both times I was started on 20 mg Prednisone and continued to take my bp medications with no adverse side effects. Have you discussed any concerns you might have with your primary care doc?
