Fludrocortisone 0.1mg is a corticosteroid with strong mineralocorticoid activity. It helps the body retain sodium and water while increasing potassium excretion, which supports blood pressure and fluid balance.
It is most commonly used in the treatment of adrenal insufficiency, including Addison’s disease, and may also be prescribed to manage orthostatic hypotension when low blood pressure is related to poor fluid or salt retention.
Fludrocortisone is taken orally and is only available with a valid prescription following clinical assessment. Long-term use requires regular monitoring of blood pressure and electrolyte levels.

Are allergic to fludrocortisone or other corticosteroids
Have systemic fungal infections
Speak to your prescriber before taking Fludrocortisone if you:
