While many are aware that decibel levels impact auditory health, prescription drugs represent a more obscure risk. Medications that can impact hearing are known as ototoxic medications, meaning they have the potential to harm the inner ear.
While many ototoxic drugs are necessary (and highly effective) for treating serious medical conditions, knowing the risks can help you recognize symptoms early and seek appropriate care if needed.
What Is Ototoxicity?
Ototoxicity refers to damage to the inner ear caused by medications or chemicals. Within the inner ear, tiny hair cells work to change sound waves into the electrical impulses that the brain understands. Should these cells be wounded, you may experience a significant change in your hearing and sense of stability.
Recognizable symptoms of an ototoxic event involve:
- A reduction in hearing that typically begins with high-pitched tones
- Persistent ringing or hissing sensations in the ears, referred to as tinnitus
- The sensation that the ear canal is stuffed or under pressure
- Equilibrium disturbances or a frequent sense of dizziness
Occasionally, the resulting hearing fluctuations are reversible. Alternatively, the damage might become irreversible if the ototoxic treatment is not stopped.
Common Ototoxic Medications
Remember that the development of ear problems is not a universal experience for those on these medications. Vulnerability frequently hinges on the amount taken, time on the drug, baseline hearing, renal health, and combined drug therapies.
A few of the most frequently cited ototoxic drugs are:
Aminoglycoside Antibiotics
Pharmaceuticals including gentamicin and tobramycin act as robust antibiotics for serious bacterial cases. According to research published in the National Library of Medicine, aminoglycosides are among the most well-known causes of medication-related hearing damage, particularly when used in high doses or for extended periods.
Particular Chemotherapeutic Agents
While platinum-centered chemo drugs like cisplatin are successful against cancer, they possess a documented risk of causing hearing loss. Clinical observation of the ears is frequently suggested throughout the course of care.
The Category of Loop Diuretics
Medications such as furosemide, used for managing fluid levels or heart issues, may impact hearing when given via IV at high concentrations.
High-Dose Aspirin and NSAIDs
Large doses of aspirin and certain nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with reversible hearing loss and tinnitus. Frequently, the condition resolves after the medicine is scaled back or ended by a doctor.
Who Should Be Most Concerned About Ototoxic Risks?
Specific demographics face an elevated risk of developing ototoxicity, including:
- Seniors in the 60-plus age bracket
- People currently living with some form of hearing loss
- Those with compromised kidney function
- Patients taking several ototoxic medications at the same time
Since the internal ear cannot grow back its hair cells, avoiding damage and catching it early is vital.
Strategies for Preventing Ototoxic Damage
If a doctor gives you a prescription with a known ototoxic profile, they might suggest initial and subsequent hearing tests. This is because identifying changes fast enables doctors to alter the amount or switch the drug before the loss becomes lasting.
It is imperative that you do not cease any medical treatment without consulting your physician. In many cases, the benefits of treatment outweigh the risks, and hearing can be monitored throughout therapy. That said, if you notice ringing in the ears, muffled hearing, or balance changes while taking medication, inform your provider right away.
When to Get an Evaluation for Hearing Changes
Any sudden or noticeable change in hearing should be evaluated by a qualified professional. Even if your signs are slight, an early checkup can find if a drug is the cause and if you need help.
Knowledge of ototoxic risks allows you to be proactive about your auditory health while managing other conditions. Through consistent testing and open dialogue with your providers, the potential for harm is often greatly diminished.
