Summary
Estrogens raise cortisol-binding globulin and total cortisol, which can distort the interpretation of the metyrapone test, and a reduced response has been described. Bazedoxifene/conjugated estrogens may therefore reduce the apparent response to metyrapone.
What this interaction means in plain words
Bazedoxifene / conjugated estrogens and Metyrapone 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
Estrogen-induced rise in cortisol-binding globulin alters cortisol measurements; the exact mechanism for reduced metyrapone response is not firmly established.
What to do
When metyrapone is used for diagnostic testing, consider holding estrogen therapy beforehand or interpret results with the estrogen effect in mind. During treatment of hypercortisolism, monitor free cortisol rather than total cortisol.
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?
