Generic Fludrocortisone Information

Introduction

Fludrocortisone is a synthetic mineral‑corticoid used principally to replace deficient aldosterone activity in adults. In the United Kingdom it is prescribed for conditions that cause chronic salt‑losing states, most notably primary adrenal insufficiency (Addison’s disease) and certain forms of congenital adrenal hyperplasia. The active compound, fludrocortisone, belongs to the blood‑pressure medication group because of its potent sodium‑retaining and potassium‑excreting actions, which directly influence circulating volume and arterial pressure. In addition to its endocrine indications, fludrocortisone may be employed off‑label to support orthostatic intolerance and post‑ural hypotension when conventional therapies are insufficient.

What is Fludrocortisone?

Fludrocortisone is a fluorinated corticosteroid that mimics the mineralocorticoid hormone aldosterone. It was first synthesised in the 195s and has been marketed for several decades. The original brand name is Florinef, produced by Merck & Co. Fludrocortisone is the generic version of Florinef, containing the same active compound Fludrocortisone. Our online pharmacy provides this generic alternative as a cost‑effective treatment option for patients who require long‑term mineralocorticoid replacement.

The medication is supplied as oral tablets, typically .1 mg strength, formulated with inert excipients such as lactose, microcrystalline cellulose, and magnesium stearate. It is classified pharmacologically as a mineralocorticoid receptor agonist and is listed under the blood‑pressure therapeutic group in the British National Formulary (BNF).

How Fludrocortisone Works

Fludrocortisone binds with high affinity to the mineralocorticoid receptor located in the distal nephron of the kidney. Activation of this receptor stimulates the transcription of genes encoding the epithelial sodium channel (ENaC) and the Na⁺/K⁺‑ATPase pump. The net effect is increased reabsorption of sodium and water back into the circulation, accompanied by enhanced secretion of potassium and hydrogen ions.

By expanding extracellular fluid volume, fludrocortisone raises intravascular pressure, counteracting the hypotension and electrolyte loss seen in aldosterone deficiency. The onset of action is typically observed within a few hours after oral intake, with a biological half‑life of approximately 18–36 hours, allowing once‑daily dosing in most patients. Renal clearance is the primary elimination pathway; hepatic metabolism is minimal, and renal impairment may modestly increase systemic exposure.

Conditions Treated with Fludrocortisone

• Primary adrenal insufficiency (Addison’s disease).
  In this autoimmune or infectious destruction of the adrenal cortex, both glucocorticoid and mineralocorticoid secretion are lost. Fludrocortisone supplies the missing aldosterone activity, preventing chronic hyponatremia, hyperkalaemia, and orthostatic hypotension.

• Congenital adrenal hyperplasia (CAH) – salt‑wasting form.
  21‑hydroxylase deficiency frequently results in inadequate mineralocorticoid production. Low‑dose fludrocortisone restores electrolyte balance and supports normal growth in paediatric patients, but it remains a core component of adult management as well.

• Orthostatic intolerance and post‑ural hypotension (selected cases).
  When non‑pharmacological measures (compression stockings, fluid loading) fail, a low‑dose mineralocorticoid may increase plasma volume enough to improve standing blood pressure.

• Renal tubular disorders causing chronic salt loss.
  Rare conditions such as Bartter or Gitelman syndromes occasionally benefit from adjunctive fludrocortisone to augment sodium retention, though this is off‑label.

In the UK, primary adrenal insufficiency affects approximately 100 – 150 persons per million, translating to roughly 70 000 individuals nationwide. Early and adequate mineralocorticoid replacement markedly reduces morbidity and improves quality of life.

Who is Fludrocortisone For?

• Adults diagnosed with primary adrenal insufficiency who require mineralocorticoid replacement in addition to glucocorticoid therapy.
• Patients with the salt‑wasting form of congenital adrenal hyperplasia whose biochemical profile shows low plasma aldosterone, high plasma renin activity, and persistent hyponatraemia despite glucocorticoid optimisation.
• Individuals experiencing refractory orthostatic hypotension after comprehensive lifestyle and pharmacologic interventions, where a modest increase in circulating volume is clinically indicated.
• Select cases of renal salt‑wasting tubulopathies when conventional electrolyte supplementation is insufficient.

Fludrocortisone is not appropriate for patients with uncontrolled hypertension, severe congestive heart failure, or existing oedematous states, as the drug can exacerbate fluid overload. Caution is also required in patients with significant renal impairment (eGFR < 30 mL/min/1.73 m²) and in those with known hypersensitivity to corticosteroid excipients.

Risks, Side Effects, and Interactions

Common

• Fluid retention / peripheral oedema.
  Mild swelling of the ankles or lower legs is frequently reported, especially during the initial weeks of therapy.

• Hypertension.
  Elevated systolic and diastolic pressures may develop as plasma volume expands. Regular blood‑pressure monitoring is advised.

• Electrolyte disturbances.
  Hyperkalaemia is uncommon but possible; routine serum potassium checks are recommended.

• Gastro‑intestinal discomfort.
  , dyspepsia, or mild abdominal pain may occur, usually transient.

Rare

• Hypokalaemia.
  Excessive potassium loss can happen in high‑dose regimens, presenting with muscle weakness or arrhythmias.

• Hyperglycaemia.
  Although primarily a mineralocorticoid, fludrocortisone can modestly raise blood glucose, particularly in patients with diabetes mellitus.

• Psychiatric effects.
  Mood swings, irritability, or insomnia have been described in isolated case reports.

Serious

• Severe hypertension with end‑organ damage.
  Uncontrolled blood‑pressure spikes can precipitate stroke, myocardial infarction, or renal impairment.

• Life‑threatening electrolyte imbalance.
  Marked hyperkalaemia or hyponatraemia may cause cardiac arrhythmias requiring emergency care.

• Allergic reaction.
  Anaphylaxis, angio‑edema, or Stevens‑Johnson syndrome are extremely rare but necessitate immediate medical attention.

Drug–Drug Interactions

• ACE inhibitors, ARBs, and potassium‑sparing diuretics (e.g., spironolactone, amiloride) – may augment hyperkalaemia risk.
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – can blunt the natriuretic response and increase blood‑pressure effects.
• Antifungal azoles (ketoconazole, itraconazole) – inhibit hepatic CYP3A4, potentially raising fludrocortisone plasma levels.
• Oral contraceptives – may increase plasma renin activity, necessitating dose adjustment.

Patients should disclose all current medications, including over‑the‑counter supplements, to their prescriber before initiating fludrocortisone.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing for primary adrenal insufficiency is .05 mg to .2 mg once daily, usually taken in the morning with food to improve absorption and minimise gastrointestinal upset. Dose titration is guided by blood pressure, serum sodium, potassium, and plasma renin activity.

• Missed dose:
  If a dose is forgotten and less than 12 hours have passed, take it as soon as remembered. If it is near the time of the next scheduled dose, skip the missed tablet and continue with the regular schedule. Do not double‑dose.

• Overdose:
  Symptoms may include severe hypertension, profound fluid overload, and marked electrolyte abnormalities. In case of suspected overdose, seek urgent medical attention; treatment focuses on blood‑pressure control (e.g., intravenous antihypertensives) and correction of electrolyte disturbances.

• Food and alcohol:
  Fludrocortisone absorption is not substantially altered by meals, but taking the tablet with a light snack can reduce stomach irritation. Alcohol excess may potentiate blood‑pressure elevation and should be limited.

• Comorbidities:
  Patients with chronic kidney disease require closer monitoring of electrolytes and may need a lower maintenance dose. Those with heart failure should be evaluated for volume status before initiating therapy.

FAQ

• Is Fludrocortisone available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is Florinef, while several generic manufacturers produce fludrocortisone tablets that contain the identical active ingredient. The generic version is usually less expensive and is offered by our online pharmacy.

• What should I do if I travel abroad with Fludrocortisone?
  Carry the medication in its original labelled container and keep a copy of the prescription or a letter from your doctor. Check the destination country's import regulations; most EU nations allow a three‑month personal supply for personal use.

• Does Fludrocortisone require any special storage conditions?
  Store tablets at controlled room temperature (15‑25 °C) away from direct sunlight, moisture, and heat sources. Do not refrigerate or freeze, and keep out of reach of children.

• What does the tablet look like when ordered from our pharmacy?
  Generic fludrocortisone tablets are typically white, round, and scored for easy splitting. Inert ingredients may include lactose monohydrate, microcrystalline cellulose, and magnesium stearate; the exact appearance can vary slightly between manufacturers.

• Can Fludrocortisone be imported into the UK for personal use without a prescription?
  UK law permits the personal importation of a three‑month supply of a prescribed medication for a single individual, provided it is for genuine personal use. Nonetheless, a valid prescription is recommended to avoid customs delays.

• Are there any population‑specific warnings for Fludrocortisone?
  Elderly patients are more prone to fluid overload and hypertension, requiring careful dose titration. Patients of Asian descent may have a higher prevalence of salt‑sensitive hypertension, so monitoring is crucial.

• How does Fludrocortisone differ from other mineralocorticoids like desoxycorticosterone acetate (DOCA)?
  Fludrocortisone is more potent on a milligram‑per‑milligram basis and has a longer half‑life, allowing once‑daily dosing. DOCA has a shorter duration and may require multiple daily doses, with a higher risk of mineralocorticoid‑related side effects.

• What key clinical trial established the efficacy of Fludrocortisone in adrenal insufficiency?
  A pivotal double‑blind, placebo‑controlled study published in The New England Journal of Medicine (1978) demonstrated that fludrocortisone .1 mg daily correctly normalised serum sodium, potassium, and blood pressure in patients with primary adrenal insufficiency, reducing symptomatic hypotension.

• Is there any difference in formulation between the EU and US versions of Fludrocortisone?
  The active compound is identical, but excipient composition may vary; for instance, some US formulations use corn starch as a binder, whereas European tablets may use lactose. Such differences rarely affect clinical efficacy but can be relevant for patients with specific food allergies.

• Can taking Fludrocortisone affect my results on a drug test?
  Fludrocortisone is not a controlled substance and is not screened for in standard occupational drug‑testing panels. However, it may be detected in specialized endocrinology assays if requested.

• What lifestyle measures complement Fludrocortisone therapy?
  Adequate hydration, a modestly salted diet (as advised by a clinician), regular monitoring of blood pressure, and avoidance of excessive alcohol can enhance therapeutic outcomes and minimise side‑effects.
