Dihydroergotamine and Miconazole: both prescribing labels mention this combination without an instruction to avoid it or change the dose.

Minor

Mentioned, no instruction to avoid. Worth knowing; rarely a reason to change anything on its own.

From the Miconazole (Oravig) label · effective 2026-01-08

Minor

Although the systemic absorption of miconazole following ORAVIG administration is minimal and plasma concentrations of miconazole are substantially lower than when given intravenously, the potential for interaction with drugs metabolized through CYP2C9 and CYP3A4 such as oral hypoglycemics, phenytoin, or ergot alkaloids cannot be ruled out.
