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.
