Fludrocortisone

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.
