Fludrocortisone is a steroid. It prevents the body from releasing substances that cause inflammation. It can be used to treat Addison’s disease and salt-losing adrenogenital syndrome.

Do not stop taking suddenly. Health changes such as infection, surgery, and stress may need a dosage change, so contact your doctor if you notice this. Wear medical ID that alerts medical personnel you take fludrocortisones.

Do not use if allergic or if you have a fungal infection. Inform your doctor of your medical history and other medications you take prior to starting this medication, especially if you’ve had mental illness, thyroid disorder, high blood pressure, or if you become pregnant/breast-feed. Steroids may weaken the immune system – inform your doctor of recent infections and avoid sick people. Do not receive a “live” vaccine while on this medication. 

Seek emergency medical attention if you encounter serious side effects, such as: overdose or allergic reaction, vision problems, swelling, shortness of breath, rapid weight gain, bloody/tarry stools, unusual thoughts/behaviors/emotions, seizure, pancreatic symptoms, low potassium symptoms, and high blood pressure symptoms. Other side effects include: acne, bruising, insomnia, slow wound healing, sweating, dizziness, digestive problems, and body fat composition changes.
