Mixing Advil PM and Melatonin
Low risk, increased effect
Low risk of harm, but the effects amplify each other. Doses that are fine alone can be far too much together.
Can you take Advil PM with Melatonin?
Advil PM contains ibuprofen and diphenhydramine. The most concerning part is Advil PM (Diphenhydramine) with Melatonin: additive sedation. Both are used as sleep aids, and stacking them mostly adds next-day grogginess rather than benefit. MixSafe rates Advil PM with Melatonin as "Low risk, increased effect" — low risk of harm, but the effects amplify each other. Doses that are fine alone can be far too much together.

Advil PM (Ibuprofen) + MelatoninLow 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.
