Uses for fludrocortisone
Fludrocortisone is a corticosteroid (cortisone-like medicine). It belongs to the family of medicines called steroids. Your body naturally produces similar corticosteroids, which are necessary to maintain the balance of certain minerals and water for good health. If your body does not produce enough corticosteroids, your doctor may have prescribed fludrocortisone to help make up the difference.
Fludrocortisone may also be used to treat other medical conditions as determined by your doctor.
Fludrocortisone is available only with your doctor's prescription.
Before using fludrocortisone
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For fludrocortisone, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to fludrocortisone or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Fludrocortisone may slow or stop growth in children or growing adolescents when used for a long time. The natural production of corticosteroids by the body may also be decreased by the use of fludrocortisone. Before fludrocortisone is given to a child or adolescent, you and your child's doctor should talk about the good fludrocortisone will do as well as the risks of using it. Follow the doctor's directions very carefully to lessen the chance that these unwanted effects will occur.
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing the use of fludrocortisone in the elderly with its use in other age groups.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
