1. Why am I using fludrocortisone?

Fludrocortisone tablet contains fludrocortisone acetate as the active ingredient. It is a type of medicine known as a corticosteroid.

Fludrocortisone is used in combination with other medicines when there is an inadequate production of one type of natural steroid hormone produced by the adrenal glands (Addison’s disease).

It is also used to treat a disorder (called salt-losing adrenogenital syndrome) which causes too much salt to be lost in the urine.

Fludrocortisone can help treat this condition by causing the kidneys to retain fluid and salt in the body.

Your doctor will have explained why you are being treated with fludrocortisone.

Ask your doctor if you want any more information about this medicine.

Fludrocortisone is not addictive.
