Not to be given to patients w/ cholestasis. Risk of severe hypotension & renal insufficiency in patients w/ bilateral renal artery stenosis or stenosis of artery to a single functioning kidney. Patients w/ recent kidney transplantation. Periodic monitoring of K & creatinine serum levels in patients w/ impaired renal function. Intravascular hypovolemia; correct vol &/or Na depletion prior to administration. Concomitant use of ACE inhibitors, ARBs or aliskiren is not recommended; close monitoring of renal function, electrolytes & BP if dual blockade therapy is absolutely necessary. Do not use ACE inhibitors & ARBs concomitantly in patients w/ diabetic nephropathy. May cause acute hypotension, hyperazotemia, oliguria, or rarely acute renal failure in patients whose vascular tone & renal function depend on activity of the renin-angiotensin-aldosterone system (eg, patients w/ severe CHF or underlying renal disease, including renal artery stenosis). Not recommended in patients w/ primary aldosteronism. Aortic & mitral valve stenosis, obstructive hypertrophic cardiomyopathy. Hypoglycemia. Diabetic patients treated w/ insulin or antidiabetics; consider appropriate blood glucose monitoring. Hyperkalemia w/ increased risk in patients w/ DM, renal impairment, on combination treatment w/ other medicinal products that affect renin-angiotensin-aldosterone system &/or K supplements; salt substitutes containing K, K-sparing diuretics, ACE inhibitors, AIIA, NSAIDs including selective COX-2 inhibitors, heparin, immunosuppressives (cyclosporin or tacrolimus), & trimethoprim; intercurrent events in particular dehydration, acute cardiac decompensation, metabolic acidosis, worsening of renal function, sudden worsening of renal condition (eg, infectious diseases), cellular lysis (eg, acute limb ischemia, rhabdomyolysis, extend trauma). Not to be taken by patients w/ rare hereditary problems of fructose intolerance. Black people. Excessive reduction of BP in patients w/ ischemic cardiopathy or ischemic CV disease may result to MI or stroke. May affect ability to drive & use machine due to dizziness or drowsiness. Mild to moderate hepatic impairment. Not recommended during pregnancy & lactation. Not recommended in childn & adolescent <18 yr.
