Fludrocortisone (Fludrocortisone acetate) — Uses, Dosage, Side Effects & Safety

Drug class: Corticosteroid (Mineralocorticoid)

Overview

Fludrocortisone is a prescription medication used to treat conditions where your body does not produce enough of its own natural steroids, especially aldosterone. It is most commonly prescribed for Addison’s disease (adrenal insufficiency) and for certain types of salt-losing adrenogenital syndrome. Fludrocortisone works by helping your body retain sodium and excrete potassium, which helps maintain proper blood pressure and salt balance. This is important for preventing dehydration and low blood pressure in people whose adrenal glands are not functioning properly. Key points for patients: Take fludrocortisone exactly as prescribed, usually once daily. Do not stop taking it suddenly without your doctor’s advice. You may need regular blood tests to monitor your body’s salt and potassium levels.
