Summary
Lidocaine is a weak CYP3A4 inhibitor and could modestly raise lemborexant levels, increasing somnolence. With topical lidocaine-prilocaine, systemic exposure is low, so a meaningful effect is unlikely.
What this interaction means in plain words
Lemborexant and Lidocaine-prilocaine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Lemborexant belongs to Central Nervous System; Lidocaine-prilocaine belongs to Genitourinary.
Why it happens
Weak CYP3A4 inhibition by lidocaine may reduce lemborexant clearance.
What to do
