What is fludrocortisone used for?
Fludrocortisone is a synthetic corticosteroid used mainly to treat problems caused by the body not making enough adrenal hormones, especially low aldosterone activity (a hormone that helps your body retain salt and water and control blood pressure). It’s commonly used for adrenal insufficiency and related conditions where mineralocorticoid effects are needed [1].
Is fludrocortisone a steroid like prednisone?
Yes, fludrocortisone is a steroid medicine, but it’s used specifically for its strong mineralocorticoid (salt- and fluid-retaining) activity rather than for the same anti-inflammatory purposes as many other corticosteroids like prednisone [1].
What does it do in the body (why would it raise blood pressure)?
By acting like aldosterone, fludrocortisone helps the kidneys retain sodium and water and promotes potassium loss. That can increase blood volume and raise or stabilize blood pressure, which is why it’s used in conditions with low aldosterone/adrenal hormone function [1].
What conditions is it prescribed for?
Common uses include:
- Adrenal insufficiency (including primary adrenal insufficiency/Addison’s disease) [1]
- Other disorders where mineralocorticoid replacement is needed, such as certain cases of impaired aldosterone production [1]
If you’re trying to figure out whether it’s appropriate for a specific diagnosis, the exact indication matters—your clinician should confirm based on your adrenal hormone labs and symptoms.
What should patients watch for?
Because it affects salt and water balance and potassium levels, fludrocortisone can cause issues like fluid retention, blood pressure increase, and low potassium. Monitoring blood pressure, symptoms (like swelling), and electrolytes (potassium, sodium) is typically important during treatment [1].
