Summary

Mifepristone is a glucocorticoid receptor antagonist and can blunt the effect of corticosteroids. In patients on long-term corticosteroids it may cause adrenal insufficiency or loss of disease control, and labeling lists chronic corticosteroid therapy as a contraindication.

What this interaction means in plain words

Methylprednisolone and Mifepristone are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.

Methylprednisolone belongs to Endocrine; Mifepristone belongs to Endocrine.

Evidence level: Moderate

Why it happens

Mifepristone blocks glucocorticoid receptors, opposing the effect of methylprednisolone.

What to do

Do not use mifepristone in patients on long-term corticosteroid therapy. Seek specialist advice if both are required, as usual steroid doses may be ineffective.
