Steroid Conversion Calculator Converts between equivalent anti-inflammatory doses of corticosteroids.
When to use: Used when switching between corticosteroids, either to change route, reduce mineralocorticoid effect, or improve dosing practicality. Equivalencies are based on anti-inflammatory potency; mineralocorticoid effects differ significantly.

Formula Equivalent anti-inflammatory doses (relative to Hydrocortisone 20mg):
Hydrocortisone 20mg = Prednisone 5mg = Prednisolone 5mg
= Methylprednisolone 4mg = Dexamethasone 0.75mg
= Betamethasone 0.75mg = Triamcinolone 4mg = Cortisone 25mg
Key Points for NEET PG
Dexamethasone has the highest anti-inflammatory potency and virtually no mineralocorticoid activity Hydrocortisone has significant mineralocorticoid activity; used for adrenal insufficiency replacement Stress dose steroids in adrenal insufficiency: Hydrocortisone 100mg IV bolus, then 50mg Q6H Dexamethasone used in raised ICP, ARDS (RECOVERY trial), meningitis, croup Equivalency is for anti-inflammatory effect only; half-lives and routes differ significantly References
