Aldactone is in a class of drugs called potassium-sparing diuretics (water pill). It is used to reduce the amount of fluid in your body without causing the loss of potassium.
Aldactone is used to treat edema (swelling) and hypertension (high blood pressure).
Aldactone is also used to treat potassium deficiency and hyperaldosteronism (a hormonal disorder).
Aldactone comes as a tablet to take by mouth. It usually is taken once a day in the morning with breakfast or twice a day with breakfast and lunch. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Aldactone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Aldactone controls high blood pressure but does not cure it. Continue to take Aldactone even if you feel well. Do not stop taking Aldactone without talking to your doctor.
Before taking Aldactone, tell your doctor if you have kidney disease; have liver disease; have diabetes mellitus; have high levels of potassium in your blood; or are taking a potassium supplement or an angiotensin-converting-enzyme inhibitor (ACE inhibitor).
You may not be able to take Aldactone, or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.
Aldactone is in the FDA pregnancy category D. This means that Aldactone is known to harm an unborn baby. Do not take Aldactone if you are pregnant.
It is not known whether Aldactone passes into breast milk. Do not take Aldactone without first talking to your doctor if you are breast-feeding a baby.
Take the missed dose as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
