Aldactone side effects

These side effects have been observed in adults:


Gynecomastia may occur during the use of spironolactone, its development seems to be related to both the dosage used and the duration of therapy; it is usually reversible when stopping the administration of spironolactone; however in rare cases it can persist.

Other rare and generally reversible adverse effects at discontinuation of therapy have been encountered, these are:

· Gastrointestinal disorders: digestive intolerance.

· Hepatobiliary disorders: hepatitis.

· Musculoskeletal and systemic disorders: cramps of the lower limbs.

· Nervous system disorders: drowsiness.

· Disorders of the reproductive organs and breast: menstrual disorders in women, impotence in men.

· Skin and subcutaneous tissue disorders: rash.

· Renal and urinary disorders: acute renal failure.


Electrolyte disturbances and hyponatraemia can be observed.

Under spironolactone, serum potassium may increase moderately. More marked hyperkalemias are reported in patients with renal insufficiency and in patients receiving potassium supplementation or ACE inhibitors: although the vast majority of these hyperkalaemias are asymptomatic, they must be rapidly corrected. In cases of hyperkalemia, treatment with spironolactone will be discontinued.
