Advil smd noght mares?

I can’t tell what you mean by “Advil smd noght mares.” It looks like a couple of words may be misspelled.

If you meant one of these, tell me which and I’ll answer precisely:
1) “Advil and night mares” (nightmares): Do you mean whether ibuprofen (Advil) can cause nightmares or weird dreams?
2) “Advil and nose bleeds” (epistaxis): Do you mean whether Advil can make nosebleeds worse?
3) “Advil and …” something else: What’s the missing word you meant?

In the meantime, if your real question is whether Advil (ibuprofen) can cause nightmares: ibuprofen commonly causes stomach upset, headache, dizziness, or—less often—sleep-related symptoms, but “nightmares” aren’t a typical or well-known side effect. The safest next step is to check the label for “sleep disturbances”/“rare side effects” and to stop taking it and seek urgent care if you have severe reactions (trouble breathing, swelling, fainting, or bleeding that won’t stop).

Reply with what you meant by “smd noght mares” (or the exact symptoms you’re seeing), plus your age and dose/timing, and I’ll tailor the answer.
