Hello. By your description, I understand that you are currently only on aliskiren and your blood pressure control is good. I would have suggested my patient to go off aliskiren if the bowel disturbances are intolerable. I would have put him on an alternative antihypertensive medication like telmisartan 40mg OD or ramipril 2.5mg OD. Both these medications would take care of your kidneys as Aliskiren. I would also suggest regular blood pressure measurement and lifestyle modifications like regular exercise, strict diet for long term control of hypertension. Hope this helps. Thank you.
