Fludrocortisone belongs to a group of medicines called corticosteroids. It is sometimes referred to simply as an oral steroid. It is used as a replacement treatment for people whose adrenal glands do not produce sufficient natural corticosteroids - a condition known as Addison's disease. It is also used for people who have had surgery to remove their adrenal glands and who therefore no longer produce natural corticosteroids.
