Comments

A corticosteroid with less mineralocorticoid activity is recommended for prolonged use, unless it is being used for physiologic replacement.

Methylprednisolone is the preferred parenteral steroid for the treatment of asthma.

4 mg hydrocortisone = ~1 mg prednisone. (anti-inflammatory response).

See Corticosteroid Equivalency Table in Supplementary Materials and References.

For acute adrenal insufficiency, hydrocortisone is used at home (single IM dose which will last 6 hours).

See Body Surface Area Calculator in Supplementary Materials and References.
