Also called ototoxicity, a drug-induced hearing loss is a hearing loss caused by medication. There are over 200 medications known to be toxic to the ear, the most common types being aminoglycoside antibiotics and chemotherapy agents. They can effect the sensory organs of the cochlea, the auditory nerve, and sometimes the vestibular system. The hearing loss can be temporary, if the drug is discontinued, or can be permanent. The most common symptoms of ototoxicity are tinnitus, balance problems, and a gradual hearing loss.
