Ototoxicity refers to the property of certain substances that can cause damage to the inner ear or auditory nerve, leading to hearing loss or balance issues. This condition can result from exposure to specific medications, such as some antibiotics and chemotherapy drugs, as well as environmental factors like loud noise or heavy metals. Symptoms of ototoxicity may include ringing in the ears, difficulty hearing, or problems with balance. Early detection is crucial, as some effects may be reversible if the offending substance is identified and removed. Regular hearing assessments can help monitor any changes in auditory function.
