How does this medication work? What will it do for me?
Spironolactone belongs to the class of medications known as diuretics (water pills). It is used to treat edema (fluid retention) that occurs with congestive heart failure, cirrhosis of the liver, and nephrotic syndrome. It is also used to treat high blood pressure and to diagnose and treat primary hyperaldosteronism (a condition where too much aldosterone is produced by the adrenal glands).
Spironolactone can also be used to treat or prevent hypokalemia (too little potassium in the body) when other methods are not appropriate. Spironolactone works by making the body lose excess water and salt but reduces the loss of potassium from the body.

How should I use this medication?
The recommended dose of spironolactone for adults ranges from 25 mg to 400 mg daily depending on the condition being treated. It is given in single or divided doses.
For children with edema (fluid retention) associated with congestive heart failure, cirrhosis of the liver, or nephritic syndrome, the daily dose is based on body weight and is given in single or divided doses.
Since this medication increases urine output, it is better to take it early in the day (with breakfast if you are taking a once-daily dose, or with breakfast and lunch if you are taking divided doses). Spironolactone may be taken with or without food. If stomach upset occurs, take the medication with food.
