Summary
Estrogens reduce corticosteroid clearance, so methylprednisolone effects may be enhanced. The legacy direction of effect on mestranol is not well supported, and the clinically relevant change is greater steroid exposure.
What this interaction means in plain words
Mestranol and Methylprednisolone have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Estrogens inhibit CYP3A4-mediated and other clearance of corticosteroids, modestly increasing methylprednisolone exposure.
What to do
No routine adjustment; monitor for increased corticosteroid effects such as fluid retention or hyperglycemia and reduce the steroid dose if needed.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
