Summary

These are both systemic corticosteroids, so combining them duplicates therapy and adds glucocorticoid adverse effects. The suggested CYP3A4 effect on dexamethasone exposure is of little significance compared with this additive effect.

What this interaction means in plain words

Cortisone and Dexamethasone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Evidence level: Low

Why it happens

Therapeutic duplication with additive glucocorticoid effects; minor possible CYP3A4 induction.

What to do

Avoid unnecessary concurrent use and count both agents toward total glucocorticoid dose; monitor glucose and blood pressure.
