Corticosteroid Equivalence Calculator

Equivalent milligram doses of systemic corticosteroids from the FDA label comparison table (oral or IV).

Current corticosteroid

The label table gives equivalent milligram dosages for oral or IV use. It does not address duration of action: agents differ in how long they act, so choose the new drug's dosing interval from its own labeling.

References and scope
  1. FDA-approved labeling, "For the purpose of comparison, the following is the equivalent milligram dosage of the various corticosteroids/glucocorticoids" (identical table in each): Dexamethasone Tablets USP, DailyMed setid 8c5375a7-7a0d-4af0-8b86-bc87698ac3d1 (label version 2026-09-04); Triamcinolone Acetonide Injectable Suspension USP, setid e55f3f0f-bd52-47e4-b77d-73ede1b41466 (2026-09-17); Celestone Soluspan (betamethasone), setid 95a19c2f-c329-4ce1-a0a7-174814aac3ad (2026-04-24).

Label limits: "These dose relationships apply only to oral or intravenous administration of these compounds. When these substances or their derivatives are injected intramuscularly or into joint spaces, their relative properties may be greatly altered." The label table also lists paramethasone (2 mg), which is not included here.

Not covered: duration of action or dosing interval, mineralocorticoid (fludrocortisone) replacement, topical, inhaled or intranasal products, and stress-dose or taper schedules. The triamcinolone and betamethasone labels cited are injectable suspensions (IM, intra-articular); the table's triamcinolone and betamethasone values are on an oral/IV basis and do not apply to those injections.
