Prescribing overview
Fludrocortisone acetate is a potent sodium-retaining corticosteroid. Human replacement labeling covers Addison’s disease and salt-losing adrenogenital syndrome; it does not establish a veterinary replacement protocol.
Key prescribing checks
- Review blood pressure, hydration, body weight and sodium/potassium trends when designing monitoring. Sodium retention, fluid accumulation and potassium loss are clinically relevant risks in human labeling.
- Reconcile diuretics, cardiac drugs and other corticosteroids. The total regimen matters more than the brand name alone.
- Replacement treatment should not be altered casually. Any planned change must account for disease stability and the possibility that additional glucocorticoid support is required.
Uses by species
Approval and evidence apply to the named product, species, route and indication. An extra-label use requires its own prescribing assessment; a human indication is not an animal approval.
Humans (reference label)
Human-approved; animal regimen not verifiedPartial replacement in adrenal insufficiency; salt-losing adrenogenital syndrome
Not interchangeable with injectable DOCP.
Use / indication source ↗Pharmacology & pharmacokinetics
Mechanism and clinical role
Promotes distal tubular sodium reabsorption and potassium/hydrogen excretion; also has glucocorticoid activity.
Absorption, distribution, metabolism and elimination
The reviewed label does not identify a studied animal species for its half-life estimates; no veterinary PK estimate is supplied here.

Contraindications & cautions
Contraindications identify circumstances where the source says a product should not be used. Precautions call for assessment or monitoring. Interactions identify combinations to review. They are distinct categories; this summary does not replace a full interaction check or the current product label.
Florinef
Canadian human oral-tablet monograph; not evidence of veterinary approval.
Contraindications · when not to use
- Drug, formulation or container-component hypersensitivity; systemic fungal infection.
- Live vaccines during immunosuppressive corticosteroid treatment.
- Ocular herpes simplex or vaccinia/varicella infection, except specified short-term emergency treatment.
Precautions & monitoring
- Monitor sodium/fluid retention, blood pressure and potassium; withdrawal requires clinical planning.
Canadian brand restrictions differ from the cited U.S. generic label.
Safety sources checked: . Selected label information; independent veterinary or veterinary-pharmacy review remains pending. A label for dogs, cats, horses or humans does not establish safety for another species.
Adverse effects
Human labeling describes hypertension, edema, potassium depletion and heart failure; prolonged corticosteroid exposure adds systemic risks.
These are selected source-reported effects, not incidence estimates or an exhaustive list. Spontaneous postmarketing reports do not by themselves establish frequency or causality.
Dosing & administration
A verified veterinary dose has not been entered for this product. Human-label dosing must not be used as an animal regimen. Consult a current species-specific clinical source and the prescribing veterinarian.
No approved veterinary dose verified in the cited human label.
Extra-label prescribing and food-animal residue requirements are separate from labeled regimens. FDA extra-label-use guidance ↗
Drug & supplement interactions
This is a selected interaction reference, not an automated or comprehensive combination checker. Reconcile prescription drugs, nonprescription products, supplements and recent treatment changes.
Florinef
Canadian human oral-tablet monograph; not evidence of veterinary approval.
- Review potassium-depleting agents, digoxin, NSAIDs and CYP3A modifiers.
Monitoring
Assess blood pressure, weight, edema and serum electrolytes; reconcile potassium-depleting drugs and cardiac medicines.
Client counseling
Do not abruptly alter chronic replacement; illness and physiologic stress require prescriber review.
This section supports the veterinary team's discharge discussion; it does not replace the product’s Client Information Sheet where one is required.
Storage & handling
Store at 20–25°C, avoiding excessive heat, in a tightly closed light-resistant container.

Florinef is a human brand identity for fludrocortisone acetate. The cited Health Canada entry verifies the brand and tablet form; it does not establish current U.S. brand availability.
Fludrocortisone acetate and fludrocortisone 21-acetate describe the ingredient salt/ester identity in product records.
This oral medication is different from injectable desoxycorticosterone pivalate (DOCP). Matching an Addison’s disease indication does not make these drugs interchangeable.
Shared ingredients do not establish interchangeable concentrations, routes, release properties, species labeling or regional availability.
