Learn More About Aldactone

Drug Name

Aldactone (Spironolactone)

Drug Uses

Aldactone is used for treating swelling and fluid retention in patients with congestive heart failure, liver cirrhosis, or kidney problems (nephrotic syndrome). It is also used for treatment of high blood pressure. It may also be used to treat or prevent low blood potassium. It may also be used to treat excess secretion of the hormone aldosterone by the adrenal gland.

How to take

Use Aldactone as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Take Aldactone by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.

Aldactone may increase the amount of urine or cause you to urinate more often when you first start taking it. To keep this from disturbing your sleep, try to take your dose before 6 pm.

Drug Class and Mechanism

Aldactone is a potassium-sparing diuretic. It works by blocking the hormone aldosterone, causing the kidney to eliminate excess water, save potassium, and lower blood pressure.

Missed Dose

If you miss a dose of Aldactone , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once. If more than one dose is missed, restart the medication and advise your doctor or pharmacist at your next appointment.

Storage

Store Aldactone at room temperature, between 59 and 77 degrees F (15 and 25 degrees C), in a tightly closed container. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Aldactone out of the reach of children and away from pets.
