Ingredient by ingredient
Advil PM (Diphenhydramine) + MXEDangerous
This risks serotonin syndrome and sudden unconsciousness, and MXE can push diphenhydramine into delirium. Do not combine at recreational doses. If someone passes out, put them on their side.
There is a high risk of serotonin syndrome from this combination. Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. While unconscious, vomit aspiration is a risk if not placed in the recovery position. MXE has a high likelihood of increasing DPH's deliriant effects at higher dosages and can greatly increase the risk of injury, mania, and psychosis. Medical dosages are unlikely to be of concern.

Advil PM (Ibuprofen) + MXELow risk, no synergy
Neither substance is expected to meaningfully change the other. Both still carry their own individual risks.
No specific interaction is documented. Ibuprofen's standing risks — stomach bleeding and reduced kidney blood flow — apply in any combination, and matter most when dehydrated, not eating, or dosing repeatedly over a long session.
