Florinef (fludrocortisone acetate) is a synthetic corticosteroid with potent mineralocorticoid activity, primarily prescribed for the management of conditions involving aldosterone deficiency. It is a cornerstone therapy in regulating electrolyte balance and blood pressure in patients with adrenal insufficiency, including Addison’s disease and congenital adrenal hyperplasia. By mimicking the action of aldosterone, it promotes sodium reabsorption and potassium excretion in the kidneys, helping to maintain hemodynamic stability and prevent life-threatening complications such as adrenal crisis. Its precise mechanism and well-established efficacy make it an essential agent in endocrinological practice.
Features
- Active ingredient: Fludrocortisone acetate
- Drug class: Synthetic corticosteroid (mineralocorticoid)
- Available formulations: 0.1 mg oral tablets
- Half-life: Approximately 18–36 hours
- Bioavailability: High oral absorption
- Metabolism: Hepatic, via CYP3A4
- Excretion: Primarily renal
Benefits
- Restores electrolyte balance by promoting sodium retention and potassium excretion
- Helps maintain normal blood pressure and intravascular volume in adrenal insufficiency
- Reduces risk of hypotension, hyponatremia, and hyperkalemia
- Supports overall stability in chronic endocrine disorders
- May improve symptoms like fatigue, dizziness, and salt craving
- Contributes to prevention of acute adrenal crisis
Common use
Florinef is indicated for partial replacement therapy for mineralocorticoid deficiency in conditions such as primary and secondary adrenal insufficiency, including Addison’s disease and salt-losing forms of congenital adrenal hyperplasia. It is also used off-label in some cases of orthostatic hypotension and autonomic dysfunction. Treatment is typically long-term and requires careful individualization based on clinical response and laboratory parameters.
Dosage and direction
The usual adult dosage ranges from 0.05 mg to 0.2 mg orally once daily, preferably in the morning to mimic physiological cortisol rhythm. Pediatric dosing is weight-based and must be carefully titrated. Dosage should be individualized based on blood pressure, serum electrolytes, and clinical signs of fluid overload or depletion. Patients should be instructed to take Florinef with food or milk to minimize gastrointestinal upset. Regular monitoring of blood pressure, serum sodium, and potassium levels is essential.
Precautions
- Use with caution in patients with hypertension, heart failure, renal impairment, or hepatic disease.
- Monitor for signs of fluid retention, edema, hypokalemia, or hypertension.
- Electrolyte levels (especially sodium and potassium) should be checked regularly.
- Dose adjustment may be necessary during periods of stress, illness, or surgery.
- Avoid abrupt discontinuation; taper under medical supervision if needed.
- Caution in elderly patients due to increased risk of adverse effects.
Contraindications
- Hypersensitivity to fludrocortisone or any component of the formulation.
- Systemic fungal infections.
- Uncontrolled hypertension.
- Severe heart failure.
- Potassium-losing nephropathies.
Possible side effects
Common side effects may include:
- Hypertension
- Fluid retention and edema
- Hypokalemia
- Headache
- dizziness
Less common but serious side effects:
- Congestive heart failure
- Severe hypokalemia leading to muscle weakness or arrhythmias
- Peptic ulcer disease
- Impaired glucose tolerance
- Increased intracranial pressure
Drug interaction
- Potassium-depleting diuretics (e.g., furosemide, hydrochlorothiazide): increased risk of hypokalemia.
- Potassium-sparing diuretics (e.g., spironolactone): may antagonize effects and cause hyperkalemia.
- CYP3A4 inhibitors (e.g., ketoconazole): may increase fludrocortisone levels.
- NSAIDs: increased risk of GI ulceration and fluid retention.
- Digoxin: hypokalemia may increase digoxin toxicity.
- Antidiabetic agents: may diminish hypoglycemic effects.
Missed dose
If a dose is missed, take it as soon as remembered unless it is almost time for the next dose. Do not double the dose to make up for a missed one. If multiple doses are missed, contact a healthcare provider for guidance, as adjustment may be needed to avoid adrenal insufficiency symptoms.
Overdose
Symptoms of overdose may include severe hypertension, edema, hypokalemia, cardiac arrhythmias, and heart failure. Treatment is supportive and symptomatic: discontinue Florinef, monitor electrolytes and cardiac function, and administer potassium supplements or antihypertensive agents as needed. Hemodialysis is not effective due to high protein binding.
Storage
Store at room temperature (20–25°C or 68–77°F), in a dry place protected from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
Florinef is widely regarded by endocrinologists as a vital and effective therapy for managing mineralocorticoid deficiency. Clinical studies and long-term use support its role in stabilizing blood pressure and electrolytes in adrenal insufficiency. Patient reports often highlight improved energy levels and reduced orthostatic symptoms, though individual responses to dosage and side effects vary. Adherence to monitoring protocols is emphasized in both clinical guidelines and practitioner experience.
