VETERINARY TEAM REFERENCE · MEDICATION

Fludrocortisone

A corticosteroid with strong mineralocorticoid activity, identified in human replacement-therapy labeling. Veterinary replacement plans require the clinician to assess electrolyte balance and the full hormone needs of the patient.

Mineralocorticoid corticosteroidProduct-specific clinical reference

Updated October 16, 2026 · Sources and review status below

For veterinarians and veterinary staff. Product-label information is distinct from extra-label clinical practice. This is not a complete prescribing formulary or an automated interaction screen. Verify the current label, exact formulation, patient and species-specific clinical reference before use. Independent veterinary/pharmacy review remains pending.

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 verified

Partial replacement in adrenal insufficiency; salt-losing adrenogenital syndrome

Not interchangeable with injectable DOCP.

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

Verify the source before prescribing. The regimens below summarize selected veterinary product labels, not every accepted veterinary use. They are not automatic substitutions between brands or formulations. Renal/hepatic disease, concurrent therapy, age, indication and clinical response can require a different plan.

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.
Interaction source ↗

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.

Brands, formulations & ingredient identity

Active ingredients

fludrocortisone acetate

Other searchable names: fludrocortisone 21-acetate

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.
