Summary
Estrogens reduce corticosteroid clearance and increase corticosteroid binding globulin, which can enhance prednisolone effects. Prednisone may have only a minor effect on estrogen levels.
What this interaction means in plain words
Conjugated estrogens and Prednisone 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 decrease prednisolone metabolism and raise binding protein levels; reciprocal effect on estrogens is minimal.
What to do
No routine adjustment is needed. Monitor for enhanced corticosteroid effects and reduce the prednisone dose if they appear.
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?
