69WARNINGS

Hypotension in Heart Failure Patients

Caution should be observed when initiating therapy in patients with heart failure. Patients with heart failure given candesartin cilexetil commonly have some reduction in blood pressure. In patients with symptomatic hypotension this may require temporarily reducing the dose of candesartin cilexetil, or diuretic, or both, and volume repletion Impaired Hepatic Function

A lower initiating dose should be considered for patients with moderate hepatic impairment. Hyperkalaemia In heart failure patients treated with candesartin cilexetil, hyperkalemia may occur, especially when taken concomitantly with ACE inhibitors and potassium-sparing diuretics such as spironolactone.
