Many common medications can affect your hearing and balance, though these side effects often go unnoticed until significant damage has occurred. Understanding the connection between medications and hearing health helps you make informed decisions about your healthcare while protecting your hearing.
As audiologists at Advanced Hearing Center, we often meet patients who are surprised to learn that their medications might be affecting their hearing. While these effects can sneak up gradually, understanding how medications interact with your hearing system helps protect your hearing health for the long term.
Your inner ear is an incredible piece of biological engineering. Think of it like a miniature power plant, constantly working to turn sound waves into signals your brain can understand. To do this work, it needs a steady supply of oxygen and nutrients delivered through some of the tiniest blood vessels in your body.
These vessels are smaller than a strand of hair, which makes them sensitive to changes in your body. When certain medications enter your bloodstream, they can affect these delicate vessels. Some medications might squeeze these vessels too tight, while others can trigger inflammation or change how blood flows through them. Without proper blood flow, the sensitive hearing cells in your inner ear can become damaged.
These hearing cells, called hair cells, are just as remarkable as they are fragile. Each one stands ready to pick up specific sounds and send them to your brain. But once these cells are damaged by medication side effects, they can't repair themselves. That's why we work closely with our patients to monitor any medication-related changes in their hearing.
The inner ear relies on a complex network of tiny blood vessels to function properly. These microscopic vessels supply oxygen and nutrients to the sensitive hair cells and other structures that make hearing possible. Because these blood vessels are so small, they can be particularly vulnerable to the effects of certain medications. Changes in blood flow, inflammation, or chemical interactions can disrupt the delicate balance needed for optimal hearing.
When medications enter the bloodstream, they can affect these vessels in various ways - some may constrict blood flow, while others might cause inflammation or changes in blood chemistry. This disruption can starve the inner ear cells of oxygen and nutrients, leading to temporary or permanent damage.
Certain medications, known as ototoxic drugs, can damage the delicate structures of the inner ear. This damage can lead to hearing loss, tinnitus (ringing in the ears), or balance problems. The inner ear contains thousands of microscopic hair cells that convert sound waves into electrical signals for the brain. When these cells are damaged or destroyed by medications, the effects are usually permanent.
Several widely-used medications have known links to hearing problems:
Aspirin and NSAIDs
Large doses of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) can affect hearing and cause tinnitus. This typically occurs when taking 8-12 doses per day. The inner ear's blood supply can become constricted, leading to reduced oxygen flow to the hair cells. The good news is these effects are usually temporary and reverse once you stop taking the medication or reduce the dosage.
Antibiotics
Some antibiotics, particularly those in the aminoglycoside family, can directly damage the hair cells in the inner ear. Medications like gentamicin, streptomycin, and neomycin pose the highest risk, especially when administered intravenously or for extended periods. These antibiotics can accumulate in the fluid of the inner ear, gradually damaging the cells responsible for hearing and balance.
Loop Diuretics
Medications like furosemide and bumetanide work by removing excess fluid from the body. When taken in large doses, they can affect the fluid balance in the inner ear. This disruption can interfere with how sound waves are processed and may lead to temporary or permanent hearing changes. The risk increases when these medications are combined with certain antibiotics.
Chemotherapy Drugs
Cancer treatments such as cisplatin and carboplatin are known to affect hearing. These platinum-based drugs can damage both the hair cells and the auditory nerve. The risk often increases with higher doses and longer treatment duration. Young children and older adults may be particularly susceptible to these effects. Recent studies suggest that up to 50% of patients receiving these treatments may experience some degree of hearing loss.
Anti-Malaria Medications
Drugs like quinine and chloroquine, used to treat malaria, can cause temporary hearing loss and tinnitus. These medications can affect both the hair cells and the auditory nerve, though the effects usually improve once treatment stops.
Understanding these risks doesn't mean you should avoid necessary medications. Instead, working with both your healthcare provider and our audiologists at Advanced Hearing Center allows for careful monitoring of your hearing health while receiving important medical treatments.
At Advanced Hearing Center, we recommend watching for these early warning signs that medications may be affecting your hearing:
If you notice any of these symptoms while taking medications, our audiologists can perform comprehensive testing to determine if your hearing has been affected. Using advanced Real Ear Measurement technology, we can precisely measure changes in your hearing and document them for your healthcare team.
Some factors can increase your risk of medication-related hearing problems:
To minimize these risks:
Professional hearing care is essential when taking medications that could affect your hearing. At Advanced Hearing Center, we provide comprehensive hearing evaluations using advanced testing equipment to detect even subtle changes in your hearing. Through real-ear measurement verification, we can precisely measure how sounds are being processed by your auditory system.
Our audiologists work closely with your other healthcare providers to monitor your hearing health while you're taking medications. We can provide detailed reports about any changes in your hearing and make recommendations for protecting your hearing moving forward.
