Recommended dosage Aldactone

Consumer Information (PDR)

ADULTS

Primary Hyperaldosteronism

Initial dosages of Aldactone are used to determine the presence of primary hyperaldosteronism (too much secretion of the adrenal hormone aldosterone). People can be tested with Aldactone over either a long or a short period of time.

In the long test, you take 400 milligrams per day for 3 to 4 weeks. If your potassium levels and blood pressure are corrected with this dosage in this time period, your physician may assume you have this condition.

In the short test, you receive 400 milligrams per day for 4 days. A laboratory test compares potassium levels while you are on Aldactone and after the medication is stopped. Your doctor may then make a diagnosis.

After the diagnosis of primary hyperaldosteronism is made and confirmed by more tests, the usual dose is 100 to 400 milligrams per day, prior to surgery. In those who are not good candidates for surgery, Aldactone is given over the long term at the lowest effective dose.

Fluid Retention (Congestive Heart Failure, Cirrhosis of the Liver, or Kidney Disorders)

The usual starting dosage is 100 milligrams daily either in a single dose or divided into smaller doses. However, your doctor may have you take daily doses as low as 25 milligrams or as high as 200 milligrams.

Your doctor may choose to adjust your dosage after an initial 5-day trial period or add another diuretic medication to this one.

Essential Hypertension (High Blood Pressure)

The usual starting dosage is 50 to 100 milligrams daily in a single dose or divided into smaller doses. This medication may be given with another diuretic or with other high blood pressure medications.

It may be up to 2 weeks before the full effect of Aldactone is seen. Your doctor can then adjust the dosage according to your response.

Hypokalemia (Potassium Loss)

Your doctor may have you take daily dosages of 25 milligrams to 100 milligrams when potassium loss caused by the effects of a diuretic cannot be treated by a potassium supplement.
