Fludrocortisone belong to a class of drugs called steroids and 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. The brand name of Fludrocortisone is Florinef. Addison’s disease is a rare, chronic endocrine disorder in which the adrenal glands do not produce sufficient steroid hormones. It can be life-threatening. Treatment for Addison’s disease involves taking hormones to replace the insufficient amounts being made by your adrenal glands, in order to mimic the beneficial effects those naturally made hormones would normally produce. Patients with adrenogenital syndrom produce an excess of the androgen hormone and insufficient amounts of cortisol and aldosterone hormones. In treating for adrenogenital syndrome, the aim is to bring hormone levels back to a normal range. Florinef is also useful during times of significant stress, severe illness, or surgery. In order to get the most benefit from this medication, follow the dosing schedule carefully, and take this medication exactly as prescribed.
