Table of contents:

Aldactone (Spironolactone) is a diuretic medicine used to treat several different conditions, such as high blood pressure, heart failure, and kidney disease. Spironolactone works by preventing the body from absorbing too much salt and keeping the right balance of fluids in the body. It is also used for hirsutism, which is an abnormal hair growth pattern in women.

Spironolactone is a medication used to treat high blood pressure and heart failure. By lowering high blood pressure, Aldactone helps reduce the risk of strokes, heart attacks, and kidney problems, and treating edema caused by certain conditions such as heart failure and liver disease.

Aldactone works by removing excess fluid, thus improving symptoms such as breathing problems. Also, it helps regulate levels of aldosterone, a natural substance produced in excess in some conditions. Spironolactone is also known as a "water pill" or potassium-sparing diuretic.

Uses and Dosage

Aldactone comes in the form of a tablet and is usually taken orally with food or milk to avoid stomach upset. Take Spironolactone regularly to get the maximum benefit from it, and to take it at the same time each day as directed. Even if you feel well, keep taking the medication, as most people with high blood pressure do not experience any symptoms.

The dosage strength and duration of Aldactone will vary depending on the condition it is being used to treat.

  • For congestive heart failure, a dosage of 25 to 50 mg tablets taken orally daily is usually recommended,
  • For hypertension, a dosage of 50 to 100 mg daily is usually prescribed.
  • For hypokalemia and edema, your doctor may start you off with a lower dose of 25 mg orally and increase the dosage if necessary. These dosages will last for two weeks or until the symptoms are cleared.
  • In cases of primary hyperaldosteronism that require surgery, the highest dose of Aldactone may be prescribed, with doses of 100 mg up to 400 mg per day.

Frequently Asked Questions (FAQ)

How long can I take Aldactone?

Treatment with ALDACTONE should be continued for at least two weeks since the maximum response may not occur before this time. Subsequently, dosage should be adjusted according to the response of the patient.

What happens when you stop Aldactone?

Talk to your doctor if you want to stop taking spironolactone. If you stop it too soon, your condition may get worse. If you're taking it for oedema, stopping it can cause fluid to build up in your body again.

Should I take spironolactone at night or morning?

You should take spironolactone once a day in the morning. However, if you are taking a high dose, you may need to take it twice a day. If you are taking it twice a day, make sure that you take the second dose no later than 4pm, as taking it later than this may cause you to wake up in the night to pee.

Can Aldactone be taken for long term?

The long-term use of spironolactone in the treatment of acne in women appears to be safe. Side effects, however, are common, although not usually a cause for stopping the drug.


It's important to purchase Aldactone from verified Canadian pharmacy.
