Using Otex with Tinnitus? Ototoxic?

I had blocked ears a few days ago and also some tinnitus. I used Otex and my ears seem to be starting to clear.

I am now aware that it's not recommended to use Otex. So can it cause permanent damage to my hearing / tinnitus?

Hearing is now better but I still have annoying tinnitus noises at night.

 

How would it cause damage? I don’t think many of the ingredients are ototoxic.

 

Thanks I just wondered why Otex leaflet says not to use if you have tinnitus?
