Spironolactone (Aldactone)

Other Names: Aldactone

What is Spironolactone Used For?

This medication may be used to lower blood pressure and/or help the body get rid of excess fluids. It may also be used to treat congestive heart failure. It is sometimes referred to as a "water pill".

How Do You Take Spironolactone?

Take this medication at the same time every day. It may be taken with or without food but if it upsets your stomach taking it with food may help. Because Spironolactone will increase your need to urinate (pass water), it is recommended that you take it first thing in the morning to avoid unnecessary trips to the bathroom during the night.

What Special Instructions Do You Need To Know?

If you miss a dose:

Take it as soon as you can but if it is almost time for your next dose, wait until then to take the medication and skip the missed dose. Do not use extra medicine to make up for a missed dose.

Your doctor may want to monitor your potassium levels while you take this medication because Spironolactone keeps your body from losing potassium.

Are There Side Effects From Taking Spironolactone?

The following side effects may occur:

• Mild nausea, vomiting, diarrhea or stomach cramps
• Breast enlargement in men
• Breast tenderness, changes in hair growth, irregular menstrual periods in women

Check with your doctor if they do not go away or are bothersome. If you notice other side effects not listed, contact your doctor or pharmacist.

When Should You Call Your Doctor?

Tell your doctor right away if you have:

• Skin rash or itching
• Confusion, weakness, irregular heartbeat or shortness of breath
• Difficulty urinating, pain in side or lower back
• Dry mouth, increased thirst or muscle cramps
• Fever, chills or sore throat

What Can You Do To Help?

Tell all health care professionals that you are on this medication. Make sure your doctor knows if you are also using Digoxin, potassium supplements, Cyclosporin, lithium, ACE inhibitors or angiotensin receptor blockers.
