Florinef
In brief
- In our pharmacy, you can buy Florinef without a prescription, with delivery in 9–21 days throughout the United Kingdom. Discreet and anonymous packaging.
- Florinef (fludrocortisone) is used to replace mineralocorticoid activity in primary adrenal insufficiency (Addison’s disease), for some salt‑wasting congenital conditions and in certain cases of orthostatic hypotension; it is a synthetic mineralocorticoid that increases sodium retention, promotes potassium excretion and expands plasma volume.
- The usual adult dose is 0.05–0.2 mg once daily (commonly 0.1 mg/day), titrated to clinical response; doses are generally kept as low as effective, with occasional maximums up to about 0.3 mg/day under specialist supervision.
- Florinef is given orally as tablets (commonly 0.1 mg), usually taken once daily, often in the morning and can be taken with or after food to reduce gastrointestinal upset.
- Some effects begin within hours, while clinically noticeable improvements in blood pressure and sodium retention are usually apparent within 24–48 hours.
- The duration of action is approximately 24 hours, so it is typically administered once daily to maintain mineralocorticoid effect.
- Avoid excessive alcohol: alcohol can worsen hypertension and fluid retention and may complicate the management of conditions treated with Florinef, so moderate or no consumption is advised and discuss alcohol use with your healthcare professional.
- The most common side effect is fluid retention (oedema) often with raised blood pressure; other frequent adverse effects include hypokalaemia and weight gain.

INN, active ingredient and main trade names
Florinef is the trade name for fludrocortisone acetate, a synthetic mineralocorticoid used for salt‑retaining replacement therapy.
Florinef is a prescription‑only medicine (POM) and is licensed in the UK for mineralocorticoid replacement.
| Product item | Details |
|---|---|
| Active ingredient | Fludrocortisone acetate |
| Strength | Typically 0.1 mg (100 mcg) tablets |
| Licence status | Prescription-only medicine (POM) |
Florinef is a prescription‑only medicine; store at controlled room temperature and consult the SPC and BNF for full prescribing information.
Primary indications and common off-label uses
Why might a clinician prescribe Florinef?
Primary indications include mineralocorticoid replacement in primary adrenal insufficiency (Addison’s disease) and maintenance management of selected cases of orthostatic hypotension.
Off‑label or adjunct uses can include some forms of salt‑wasting congenital adrenal hyperplasia and selected autonomic dysfunctions under specialist supervision.
Typical patient reasons to take Florinef are to reduce dizziness, prevent fainting and stabilise blood pressure.
| Indication | Typical starting dose |
|---|---|
| Primary adrenal insufficiency | 0.05–0.1 mg once daily |
| Orthostatic hypotension (selected cases) | 0.05–0.1 mg once daily |
Forms and pack sizes
Which forms and strengths are available?
Florinef is primarily supplied as oral tablets, commonly 0.1 mg strength, with pack sizes often 30 or 100 tablets for monthly supplies.
| Form | Strength | Pack sizes |
|---|---|---|
| Tablet | 0.1 mg (100 mcg) | 30 tablets; 100 tablets |
Mechanism in plain language for patients
How does Florinef actually help with dizziness and fainting?
Fludrocortisone is a mineralocorticoid analogue that increases sodium reabsorption and promotes potassium excretion in the kidney.
Increased sodium retention raises circulating blood volume and therefore supports blood pressure, which helps prevent dizziness and syncope due to low circulating volume.
- Mechanism → effect → patient benefit: Sodium retention → Higher blood volume → Fewer fainting spells
Typical regimens, titration and monitoring needs
What dose will a patient start on and how is it adjusted?
Typical adult dosing is low and conservative, often 0.05–0.2 mg once daily with many patients starting at 0.05–0.1 mg daily and titrating by symptoms and blood tests.
Children require specialist, weight‑adjusted dosing and endocrinology review.
Monitor supine and standing blood pressure and serum potassium when adjusting dose.
| Step | Action |
|---|---|
| Start | 0.05–0.1 mg once daily |
| Assess after 1–2 weeks | Review symptoms, supine/standing BP, serum potassium |
| Adjust | Increase or decrease dose based on clinical and electrolyte response |
Missed dose advice: take when remembered unless close to the next dose; do not double up.
Emphasise ongoing monitoring for blood pressure, weight and serum potassium.
What to watch for and when to seek help
Which side effects are common and which are urgent?
Common and important effects include fluid retention, peripheral oedema, hypertension and hypokalaemia with symptoms such as muscle weakness or cramps.
Other concerns include exacerbation of heart failure, headaches and mood changes; skin reactions are less common.
Urgent red flags are sudden rapid weight gain, severe breathlessness, chest pain, very high blood pressure or profound muscle weakness — these require immediate medical attention.
| Side effect | Monitoring frequency |
|---|---|
| Hypokalaemia | Baseline and periodic serum potassium checks |
| Hypertension / fluid retention | Regular BP and weight checks |
| Cardiac symptoms | Immediate review if breathlessness or chest pain |
Who needs extra caution and key interactions
Who should a prescriber and pharmacist watch more closely when prescribing Florinef?
Absolute contraindications include known hypersensitivity to fludrocortisone or excipients and systemic fungal infections.
Caution is advised in uncontrolled hypertension, heart failure, severe renal impairment and conditions that predispose to hypokalaemia.
| Drug class | Effect | Pharmacist action |
|---|---|---|
| Loop and thiazide diuretics | Increase risk of hypokalaemia | Check potassium and notify prescriber |
| Systemic corticosteroids | May increase mineralocorticoid effects | Monitor BP and electrolytes |
| Drugs affecting CYP enzymes | May alter steroid exposure | Liaise with prescriber for dose adjustment |
Special populations — practical pharmacy advice
How does use differ in pregnancy, breastfeeding, children and older adults?
Pregnancy: fludrocortisone may be used when benefits outweigh risks and specialist obstetric or endocrine input is recommended because dose requirements can change in pregnancy.
Breastfeeding: passage into breast milk appears low, but specialist advice is recommended.
Children: specialist paediatric dosing applies, particularly in congenital adrenal hyperplasia — do not extrapolate adult doses.
Older adults: increased sensitivity to hypertension, heart failure and electrolyte disturbances; start low and monitor renal function closely.
- Pregnancy: discuss with obstetrics/endocrinology teams.
- Breastfeeding: consult specialist if there are concerns.
- Children: managed by paediatric endocrinologists with weight‑based doses.
- Elderly: slow titration and regular renal monitoring advised.
How to take Florinef and live with therapy
What practical advice should pharmacists give to patients?
Patients are usually advised to take Florinef in the morning with food to minimise gastrointestinal upset and to align with day‑time blood pressure needs.
Encourage home blood pressure checks, including supine and standing readings if instructed by the prescriber.
Advise daily or regular weight checks to detect fluid retention early and to report dizziness, breathlessness or rapid weight gain promptly.
Warn that salt intake and diet may be discussed with the prescriber since Florinef promotes sodium retention.
Stress the importance of not stopping the medicine abruptly and of presenting a valid prescription for repeat dispensing.
- Take in the morning with food.
- Do not double up after a missed dose.
- Report red‑flag symptoms immediately.
- Keep regular BP and weight records if advised.
Legal status

When Florinef is not suitable — other options
What are reasonable alternatives if Florinef cannot be used?
Direct alternatives for mineralocorticoid replacement are limited.
For orthostatic hypotension alternative agents such as midodrine may be considered depending on the aetiology.
| Drug | Indication | Main effect |
|---|---|---|
| Florinef (fludrocortisone) | Mineralocorticoid replacement | Sodium retention, BP support |
| Midodrine | Orthostatic hypotension | Peripheral vasoconstriction |
Referral back to endocrinology is advised when alternatives are being considered or when standard therapy is ineffective.
