Fludrocortisone
In StockFludrocortisone is a corticosteroid medicine used to treat conditions involving low levels of adrenal hormones, such as Addison’s disease and certain forms of adrenal insufficiency. It works by helping regulate sodium and fluid balance in the body, supporting normal blood pressure and electrolyte levels. This action helps maintain proper hormone function. Use fludrocortisone only as directed on the product label or by a healthcare professional.
What is Fludrocortisone?
Fludrocortisone is a prescription medication classified as a synthetic mineralocorticoid corticosteroid. It helps the body regulate salt and fluid balance and supports normal blood pressure.
It is commonly prescribed for:
Primary adrenal insufficiency such as Addison disease
Salt losing forms of congenital adrenal hyperplasia
Conditions where the body cannot maintain proper sodium and fluid levels
Certain cases of orthostatic hypotension when recommended by a specialist
Fludrocortisone is primarily available as:
Oral tablets in different strengths commonly low dose formulations
Strength availability may vary by country and manufacturer.
What is the Recommended Dosage of Fludrocortisone?
The appropriate dosage varies depending on:
The underlying condition
Age and body weight
Blood pressure and electrolyte levels
Kidney and heart function
Response to treatment
Fludrocortisone is usually taken once daily, but dosing schedules differ between patients.
Healthcare providers often adjust treatment based on:
Blood sodium and potassium levels
Symptoms such as dizziness or swelling
Blood pressure readings
Dosing must follow instructions from an endocrinologist or other qualified medical specialist. Patients should not change the dose without medical guidance.
How Fludrocortisone Works
Fludrocortisone acts similarly to the natural hormone aldosterone, which is produced by the adrenal glands.
It works by:
Increasing sodium retention in the kidneys
Promoting fluid balance
Supporting blood pressure stability
Helping maintain electrolyte balance
This action helps manage symptoms caused by adrenal hormone deficiency. Fludrocortisone controls hormone imbalance but does not cure the underlying adrenal condition.
