Perform careful appraisal of the benefit/risk if an episode of unstable angina pectoris (major or not) may occur during the 1st mth of therapy. May cause hypotension in patients who have been vol-depleted (eg, by diuretic therapy, dietary salt restriction, dialysis, diarrhea or vomiting) or who have severe renin-dependent HTN, symptomatic heart failure w/ or w/o associated renal insufficiency, severe degrees of heart failure, ischemic heart or cerebrovascular disease. Mitral valve stenosis & obstruction in the outflow of the left ventricle eg, aortic stenosis or hypertrophic cardiomyopathy. Renal impairment (CrCl <60 mL/min), bilateral renal artery stenosis or stenosis of the artery to a solitary kidney, preexisting renal impairment. Routine monitoring of K & creatinine. Hemodialysis. Recent kidney transplantation. Increased risk of hypotension & renal insufficiency in patient w/ bilateral renal artery stenosis or stenosis of the artery to a single functioning kidney. Angioedema. Concomitant use w/ NEP inhibitors (eg, racecadotril) & mTOR (eg, sirolimus, everolimus, temsirolimus) & gliptins (eg, linagliptin, saxagliptin, sitagliptin, vildagliptin). Anaphylactoid reactions during desensitization & LDL apheresis. Discontinue in patients who develop jaundice or marked elevations of hepatic enzymes. Neutropenia/agranulocytosis/thrombocytopenia/anemia. Periodic monitoring of WBC in patients w/ collagen vascular disease, immunosuppressant therapy, treatment w/ allopurinol or procainamide, or a combination of these complicating factors especially if there is preexisting impaired renal function. Black patients. Non-productive & persistent cough. Discontinue 1 day prior to surgery. Risk factors for hyperkalemia include renal insufficiency, worsening renal function, patients >70 yr, DM, intercurrent events particularly dehydration, acute cardiac decompensation, metabolic acidosis, concomitant use of K-sparing diuretics (eg, spironolactone, eplerenone, triamterene, or amiloride), K supplements or K-containing salt substitutes, taking other drugs associated w/ increases in serum K (eg, heparin, co-trimoxazole). Closely monitor glycemic control in diabetic patients treated w/ oral antidiabetic agents or insulin. Concomitant use w/ lithium; K-sparing drugs, K supplements or K-containing salts. Risk of hypotension, hyperkalemia & decreased renal function w/ dual blockade of renin-angiotensin-aldosterone system. Contains <1 mmol Na (23 mg)/tab ie, essentially 'Na-free'. Not recommended in patients w/ primary aldosteronism. Galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption. May impair ability to drive or operate machinery. Pregnancy (1st trimester) & lactation. Not recommended in childn & adolescent <18 yr.
