Spironolactone (Aldactone)

Spironolactone is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Spironolactone is used to treat heart failure, high blood pressure (hypertension), or hypokalemia (low potassium levels in the blood).

Spironolactone also treats fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney disorder called nephrotic syndrome.

Spironolactone is also used to diagnose or treat a condition in which you have too much aldosterone in your body. Aldosterone is a hormone produced by your adrenal glands to help regulate the salt and water balance in your body.

Spironolactone may also be used for purposes not listed in this medication guide.

Spironolactone has caused tumors in animals but it is not known whether this could occur in people. Do not use this medicine for any condition that has not been checked by your doctor.

How To Take Spironolactone

Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Do not share this medicine with another person, even if they have the same symptoms you have.

You may take spironolactone with or without food, but take it the same way each time.

While using spironolactone, you may need frequent blood tests.

This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using spironolactone.

If you need surgery, tell the surgeon ahead of time that you are using spironolactone. You may need to stop using the medicine for a short time.

If you are being treated for high blood pressure, keep using this medication even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.

Store at room temperature away from heat, light, and moisture.

If You Miss A Dose

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What To Avoid While Taking Spironolactone

Drinking alcohol can increase certain side effects of spironolactone.

Do not use salt substitutes or low-sodium milk products that contain potassium. These products could cause your potassium levels to get too high while you are taking spironolactone.

Avoid a diet high in salt. Too much salt will cause your body to retain water and can make this medication less effective.

Spironolactone may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Follow your doctor’s instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.

Drugs That Affect Spironolactone

Taking this medicine with other drugs that make you dizzy or lower your blood pressure can worsen these effects. Ask your doctor before taking a sleeping pill, opioid pain medicine, a muscle relaxer, or medicine for anxiety, depression, or seizures.

Tell your doctor about all your current medicines and any you start or stop using, especially:

• cholestyramine, digoxin, lithium, trimethoprim;
• heart or blood pressure medicine (especially another diuretic);
• medicine to prevent a blood clot; or
• NSAIDs (nonsteroidal anti-inflammatory drugs)–aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
