Risks and Warnings for Fludrocortisone

Skip risks section. Skip to common concerns section.
    • Higher risk if:
    • Lowering dose or stopping too quickly especially after long-term treatment
    • Stress such as trauma, surgery or infection

    If you've been taking corticosteroids like Fludrocortisone for a long time, lowering your dose or stopping it too quickly can be really dangerous since your body can't respond to stress. Symptoms include joint or muscle pain, extreme low energy and depression. Changes in your Fludrocortisone dose need to be done slowly over time. Talk to your doctor before you make any changes or stop it.
