What is an Ototoxic Medication
Ototoxic medications are drugs that can damage your inner ear, resulting in tinnitus1, or temporary or permanent hearing loss. If your hearing loss is diagnosed as sensorineural, it is important to consult with your doctor and Pharmacist on the medications that get prescribed to you, as these particular drugs have been known to aggravate an already existing hearing problem.

It is good to know that with several of these drugs, like aspirin, hearing loss returns to normal after you stop taking it, no matter how long it has been used.
