    INSTRUCTIONS

    These dose relationships only apply to oral or IV administration. Glucocorticoid potencies may differ greatly following intramuscular or intra-articular administration.

    When to Use
    Pearls/Pitfalls
    Why Use
    • Patients on chronic steroids may need to have their doses converted to another form for drug shortages or availability or formulation (pill, liquid, IV vs oral), for example.
    • Patients receiving a short “burst” dose of steroids may also need conversion based on formulation as well.
    • These dose relationships only apply to oral or IV administration.
    • Glucocorticoid potencies may differ greatly following IM or intra-articular administration.
    • Fludrocortisone is not used for glucocorticoid effects (only for its mineralocorticoid properties).

    Different glucocorticoids possess different duration of effect and potency; it is important to consider both factors when converting a steroid.

    Advice

    Remember to consider not just potency but also duration of effect. Dexamethasone typically requires much less frequent dosing due to its very long half-life and duration of action.
