An individual can experience hearing loss for a variety of reasons. Some people are born with hearing loss, while others may develop hearing-related problems due to earwax buildup, ear infections, or exposure to loud noise. However, exposure to certain chemicals, antibiotics, and metals can also damage the inner ear and cause hearing loss. This type of damage is known as ototoxicity.
Keep reading to learn more about “ear poisoning,” otherwise known as ototoxicity. El Dorado Hearing explains what it is, its causes, symptoms, and potential treatment options.
What Is Ototoxicity?
Individuals may experience hearing loss due to exposure to substances that are toxic to the inner ear, a condition referred to as ototoxicity. It occurs when certain chemicals or medications damage structures in the inner ear or affect the auditory and balance systems. Exposure may occur through ingestion, absorption, or inhalation, depending on the substance. As a result, patients may experience hearing or balance problems that can be temporary or permanent.
Ototoxicity can result from certain prescription medications, over-the-counter medications, and chemical products. If you are taking medication or working with chemicals that may pose a risk, be aware of potential side effects and follow appropriate safety precautions. Do not stop taking prescribed medication without consulting your healthcare professional. Depending on the substance and extent of the damage, some effects may improve after exposure ends, while others may be permanent. An audiologist can help assess hearing changes and discuss appropriate treatment options.
Symptoms of Ototoxicity
Recognizing possible symptoms of ototoxicity early and seeking medical attention can help prevent further damage when possible. One common symptom is tinnitus, which may cause ringing or buzzing in the ears. Ototoxicity can also affect the balance system. Symptoms vary depending on the substance, the level and duration of exposure, and the individual’s health. Other symptoms to watch for include:
- Dizziness
- Tripping or unsteadiness
- Loss of coordination
- Vertigo
- Visual disturbances, such as the sensation that the surroundings are moving
- A feeling of fullness in the ears
- Ringing in the ears (tinnitus)
- Difficulty hearing high-frequency sounds
- Hearing loss in one or both ears
Symptoms may develop gradually over time or appear rapidly, depending on the circumstances and the type of exposure.
How to Treat Ototoxicity
Ototoxicity can cause symptoms similar to those of other hearing and balance conditions, making diagnosis challenging. There is no single test that confirms every case of ototoxicity. Diagnosis typically involves reviewing medication and chemical exposure history, conducting a medical examination, and performing hearing and balance assessments when appropriate.
If you suspect exposure to a harmful chemical or medication, seek medical advice promptly and avoid further exposure when it is safe to do so. Do not discontinue prescribed medication without speaking to your healthcare professional. Treatment depends on the substance involved and the extent of the damage. Although some forms of damage may not be reversible, appropriate care can help manage symptoms and support communication and balance.
Depending on the severity of hearing loss, a hearing specialist may recommend hearing aids or, in some cases, a cochlear implant evaluation. If balance problems are present, a healthcare professional may recommend vestibular rehabilitation or refer you to a physical therapist with appropriate expertise.
