For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Miconazole is a CYP3A4 inhibitor, but systemic absorption after vaginal use is low, so a meaningful increase in solifenacin exposure is unlikely for most patients. Greater absorption may occur with prolonged use or damaged mucosa.
What this interaction means in plain words
Miconazole vaginal and Solifenacin 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
Possible CYP3A4 inhibition by absorbed miconazole decreases solifenacin metabolism.
What to do
No dose adjustment is usually needed; monitor for anticholinergic effects if vaginal miconazole is used repeatedly or long term.
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?
