Contraindications & Cautions
Should be used with caution in people with (or a genetic predisposition to) hypertension or fluid retention, and is contraindicated in hypotonia, severe renal insufficiency, hypokalaemia, liver cirrhosis and cholestatic liver disease. The effects are likely to be dose-dependent. As it may questionably reduce testosterone levels in men, caution should be used in men with a history of impotence, infertility or decreased libido. Precaution should be taken with people with prolonged gastrointestinal transit time, anorexic and elderly patients. Patients on high doses for a prolonged period (>2 weeks) should be placed on a low sodium, high potassium diet. Excessive or prolonged ingestion has resulted in symptoms of an apparent “mineralocorticoid excess syndrome” typical of primary hyperaldosteronism, namely hypertension, sodium, chloride and water retention, hypokalaemia and weight gain, but also in low levels of plasma renin activity, aldosterone and antidiuretic hormone. This can be abated after cessation of intake, adequate potassium replacement and spironolactone therapy.
