Fludrocortisone is a mineralocorticoid, a hormone that helps to regulate the concentration of sodium and potassium in the body. It is used to treat Addison's disease (adrenocortical insufficiency, hypoadrenocorticism). This condition generally requires a lifetime of treatment. Fludrocortisone may also be used to lower the potassium level in animals with hyperkalemia (high blood levels of potassium).
Side effects are rare. They generally occur if the dosage is excessive or if the medication is discontinued too rapidly. Side effects may include high blood pressure, water retention, and low potassium levels or muscle weakness. Contact your veterinarian if you notice frequent urination, urinary incontinence or excessive thirst.Other side effects may occur. If you notice anything unusual, contact your veterinarian.

Make sure to tell your veterinarian what other medication you are giving to your pet. Quite often your veterinarian may prescribe two different medications, even if a drug interaction may occur. In this case, your veterinarian may vary the dose and/or monitor your pet more closely. The following drugs can potentially interact with fludrocortisone acetate: potassium-depleting diuretics (e.g. hydrochlorothiazide, furosemide). Contact your veterinarian if your pet experiences any unusual reactions when different medications are given together.

If your pet displays symptoms of an allergic reaction, call your veterinarian immediately or go to a veterinary emergency clinic.
