Conivaptan inhibits CYP3A4 and might raise prednisolone concentrations. Because conivaptan is given only for a short period and prednisolone is only partly CYP3A4 dependent, the effect is likely small.
What this interaction means in plain words
Conivaptan and Prednisolone 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
CYP3A4 inhibition by conivaptan reduces prednisolone metabolism.
