Actually, quinine is linked to deafness in some (rare?) cases. Not sure how much you have to consume, but we know a family living in Africa who needed to use quinine for their young son and he lost his hearing. I've also heard that quinine was a successful treatment for restless leg syndrome and doctors either no longer prescribe it or are hesitant to do so.
I'm assuming the quantities necessary for any sort of harm are quite large, but quinine is no longer considered completely safe.
