See Contraindications. Concomitant ACE inhibitors (eg, ramipril): not recommended. Dual inhibition of the renin-angiotensin system with ARBs, ACEIs, or aliskiren may increase risk of hypotension, hyperkalemia, renal function changes; monitor closely.

Hyperkalemia with K+ supplements, K+ sparing diuretics, K+ containing salt substitutes. Hypokalemia with corticosteroids, ACTH. Orthostatic hypotension potentiated by alcohol, CNS depressants.
