Steroid Equivalence Converter

Convert between corticosteroid doses using the standard glucocorticoid-equivalence table - hydrocortisone, cortisone, prednisone, prednisolone, methylprednisolone, triamcinolone, dexamethasone, and betamethasone.

Example

Dose
5 mg
From steroid
prednisone
To steroid
methylprednisolone

Result: 5 mg prednisone ~ 4 mg methylprednisolone

What this is

Sophie Well takes the source steroid, the source dose, and the target steroid and returns the equivalent dose along with the relative anti-inflammatory and mineralocorticoid potencies and the approximate duration class (short, intermediate, long) so the converted dose is not just numerically right but pharmacodynamically sensible.

When to use it

Use this when transitioning a patient between IV and oral steroids on admission or discharge, when calculating a taper that starts on one agent and finishes on another, or when reviewing whether a stress-dose hydrocortisone regimen matches an outpatient prednisone equivalent. The equivalence values are anti-inflammatory potency, not full pharmacokinetics - duration, mineralocorticoid activity, and HPA-axis suppression vary by agent - so the converted dose is the starting point for clinical judgment, not a substitute for it.

How this is calculated

Glucocorticoid equipotent-dose ratios per standard pharmacology references (e.g., Goodman & Gilman; Brunton, Hilal-Dandan, Knollmann eds., 13e). Mineralocorticoid activity noted separately; verify against your formulary.
