Hi again. I took a herbal med that contained bearberry (containing hydroquinone/arbutine) for a bladder infection some time ago. The doctor proposed an antibiotic but I am against taking them so I resorted to this herbal med. No ear-related side effects are stated by the pharmaceutical company. The dosage is 420 mg hydroquinone daily. Now I did some research and bearberry or hydroquinone/arbutin has references to being ototoxic as in causing ringing in the ears. Does anyone know more about this? Could the effect on tinnitus be delayed because my tinnitus worsened a few weeks after taking the med and I am still looking for a cause. In case there is a connection with my worsening of tinnitus some weeks later: Is the effect reversible?
