Hello from JustAnswer.
Tinnitus is not a common side effect to the quetiapine, but it has been reported. It is so infrequent that we would typically look for other possible causes of tinnitus, but if no other cause is apparent, then it is more likely due to the quetiapine. The ultimate proof that it is from the quetiapine would be if the symptoms resolves if the quetiapine is stopped, but there should also be some consideration of what should be done instead of taking the quetiapine.
If I can provide any additional information, please let me know.
Yes, it can happen from withdrawal from zopiclone, but if both the original tinnitus and the later tinnitus were form withdrawal, it would usually not have a couple days without the tinnitus.
It is not likely from the amount of naproxen that you have taken, but you have also already stopped the naproxen, so in the rare situation in which the naproxen was the cause, it should improve soon from having already stopped the naproxen.
Tinnitus is not reported as a side effect to the olanzapine.
