Discontinue treatment immediately & not to be restarted if patient develops severe, chronic diarrhea w/ substantial wt loss in absence of other apparent etiologies. Not recommended in patients w/ primary aldosteronism. Symptomatic hypotension in patients who are vol &/or Na depleted by vigorous diuretic therapy, dietary salt restriction, diarrhea or vomiting. Acute hypotension, azotemia, oliguria or acute renal failure in patients w/ severe CHF or underlying renal disease including renal artery stenosis. Increased risk of severe hypotension & renal insufficiency in patient w/ bilateral artery stenosis or stenosis of artery to single functioning kidney; hyperkalemia in elderly >70 yr, diabetic patients, those w/ renal insufficiency, concomitantly treated w/ other medicinal products increasing K levels, & intercurrent events. Excessive BP decrease in patients w/ ischemic heart disease or ischemic cerebrovascular disease resulting in MI or stroke. Patients w/ recent kidney transplant; aortic mitral valve stenosis or obstructive hypertrophic cardiomyopathy. Less BP lowering effect in black patients. Correct vol &/or Na depletion before administration. Close monitoring of serum K in patients w/ intercurrents events eg, dehydration, acute cardiac decompensation, metabolic acidosis, worsening or sudden worsening of renal function (eg, infectious disease), cellular lysis (eg, acute limb ischemia, rhabdomyolysis, extended trauma); renal function, electrolytes & BP if dual blockade therapy is considered. Not to be used concomitantly w/ ACE inhibitors & ARBs in patients w/ diabetic nephropathy. Not recommended in combination w/ lithium. Concomitant use w/ salt substitutes containing K, K-sparing diuretics, ACE inhibitors, AIIA, NSAIDs (including selective COX-2 inhibitors), heparin, immunosuppressor eg, ciclosporin or tacrolimus, trimethoprim; aliskiren. Not to be taken in patients w/ glucose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption. Not recommended in severe renal (CrCl <20 mL/min) & hepatic impairment. End-stage renal impairment ie, CrCl <12 mL/min. Periodic monitoring of serum K & creatinine levels in patients w/ impaired renal function. Discontinue treatment immediately & start alternative therapy when pregnancy is diagnosed. Not recommended during 1st trimester of pregnancy & in lactation. Closely observe infants born from mothers taking AIIA for hypotension. Childn & adolescents <18 yr.
