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 this medicine 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.

This product is available in the following dosage forms:

  • Tablet

Before Using

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 this medicine, the following should be considered:

For non-prescription products, read the label or package ingredients carefully.

Pediatric

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 this medicine. Before this medicine is given to a child or adolescent, you and your child's doctor should talk about the good this medicine 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.

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.
