FDA Label Information
7.4 Dual Blockade of the Renin-Angiotensin System (RAS) Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Do not coadminister aliskiren with irbesartan tablets in patients with diabetes. Avoid use of aliskiren with irbesartan tablets in patients with renal impairment (GFR <60 mL/min).
