I've said this before so sorry to repeat, but I sincerely believe this is relevant to any drug that has what I call a "hearing signature" (anything that messes with hearing/auditory system...not just 'tinnitus' as a listed side-effect).
If taking Ibuprofen/NSAID's or other potentially ototoxic drugs (like most of the ...'cin ending antibiotics - aminoglycosides, etc.) stay out of loud sound environments and/or protect fully until plasma clearing is complete!
I have personal experience of this 'drug -sound combo' causing lasting tinnitus volume increase. Plus causing new tinnitus in a few friends - construction workers banging nails all day while taking Ibuprofen. Ex wife - playing marimba in a band while taking Ibuprofen; etc.
I'm convinced it is also a factor in the high rates of tinnitus in combat military personnel, as eating pain-killers like Ibuprofen is almost du jour for the conditions they are under!
So, Ibuprofen is likely to be fine even with tinnitus (I use it occasionally with no increase in volume), but Ibuprofen PLUS loud sound = danger! My doc is tending to agree with me too now that I brought it to his attention.
Better to play it safe. If need the pills, keep it quiet.
