A considerably large percentage of deafness is caused by the improper use of drugs, especially the ototoxic antibiotics like streptomycin, gentamycin, neomycin, kanamycin, tobramycin, vancomycin and polymyxin. In addition, salts of salicylic acid, chloromycetin, quinine, chloroquine as well as the chemotherapeutic drugs for tumor like mustargen and vincristins have certain ototoxic effects. Accordingly, these drugs should be strictly controlled in clinic so as to avoid deafness due to auditory injury.

Apart from these medicines, correct the bad habits like picking the ears to prevent infection of antrum auris. Meanwhile, moderate sexual life and eat proper tonic products. These points are also beneficial to the prevention and treatment of tinnitus and deafness in middle-aged people. More information, please continue to read Properties of Chinese Herbs.
