Fludrocortisone is in a class of drugs called steroids. Fludrocortisone prevents the release of substances in the body that cause inflammation. Fludrocortisone is used to treat conditions in which the body does not produce enough of its own steroids, such as Addison's disease, and salt-losing adrenogenital syndrome. Fludrocortisone may also be used for other purposes not listed in this medication guide. You should not use this medication if you are allergic to fludrocortisone, or if you have a fungal infection anywhere in your body. Before taking fludrocortisone, tell your doctor about all of your medical conditions, and about all other medicines you are using.
Fludrocortisone mimics the actions of aldosterone which is a steroid that is naturally produced by the body. The physiological effects of fludrocortisone are dose dependent. Small oral doses of fludrocortisone cause an increase in blood pressure, sodium retention, and increases urinary potassium excretion. Larger doses of fludrocortisone inhibit the secretion of hormones from the adrenal gland.
