Corticosteroid Conversion

Calculate equivalent doses between corticosteroids

mg

Accepts decimal values (e.g. 7.5, 15.25)

Equivalence Table

Anti-inflammatory doses equivalent to 5 mg prednisone

Corticosteroid Dose (mg) Potency Duration
Hydrocortisone 20 Low Short (8–12 h)
Cortisone 25 Low Short (8–12 h)
Prednisone 5 Intermediate Intermediate (12–36 h)
Prednisolone 5 Intermediate Intermediate (12–36 h)
Methylprednisolone 4 Intermediate Intermediate (12–36 h)
Deflazacort * 6 Intermediate Intermediate (12–36 h)
Dexamethasone 0.75 High Long (36–72 h)
Betamethasone 0.6 High Long (36–72 h)

* Deflazacort equivalence varies between sources. Standard references cite 6 mg ≈ 5 mg prednisone. For FDA-approved weight-based dosing in specific indications (e.g. Duchenne muscular dystrophy), refer to the Emflaza prescribing information.

Clinical Considerations

Anti-inflammatory equivalence

Doses are based on relative anti-inflammatory potency. Mineralocorticoid activity varies between corticosteroids and should be considered when selecting therapy.

Conversions in practice

Conversions are approximate and may vary depending on the clinical indication, route of administration and individual patient response. Individual adjustments may be necessary.

Mineralocorticoid activity

Hydrocortisone and cortisone have clinically relevant mineralocorticoid activity. Dexamethasone and betamethasone have minimal mineralocorticoid activity and are not suitable for adrenal replacement.

Note: This calculator provides conversions based on standard anti-inflammatory equivalences. The optimal dose should be adjusted individually based on clinical condition, treatment response and adverse effects. Never stop corticosteroids abruptly without medical guidance.
