FAQs
Is dexamethasone stronger than prednisone?
Yes. Dexamethasone is approximately 7-10x more potent than prednisone on a mg-for-mg basis. This means the doses are much smaller. It also has no mineralocorticoid activity (unlike prednisone), making it less likely to cause sodium retention and fluid accumulation.
How long does dexamethasone last in a dog?
Dexamethasone has a long biological half-life of 36-72 hours, significantly longer than prednisone (12-36 hours). This means once-daily or every-other-day dosing is typical, and suppression of the adrenal axis can persist for days after the last dose.
