Hundreds of medications list tinnitus as a possible side effect, but a smaller group of drug classes are the most common culprits. These include certain antibiotics, platinum-based chemotherapy drugs, high-dose aspirin, loop diuretics, and some antidepressants. Whether the ringing is temporary or permanent depends largely on which drug caused it, how long you took it, and your kidney function.
High-Dose Aspirin and Pain Relievers
Aspirin is one of the most widely recognized tinnitus triggers. At high doses, roughly 6 to 8 grams per day (the equivalent of 12 to 16 regular-strength tablets), aspirin reliably causes both hearing loss and tinnitus. In one documented case, 10 grams of aspirin produced severe hearing loss and loud tinnitus within 22 hours. The good news is that aspirin-induced tinnitus is almost always reversible once you stop or reduce the dose.
What catches some people off guard is that even chronic low therapeutic doses of aspirin, the kind taken daily for heart health, can sometimes cause tinnitus without noticeable hearing loss. Other over-the-counter pain relievers like ibuprofen and naproxen carry a similar risk at high doses, though the effect is generally temporary.
Aminoglycoside Antibiotics
Aminoglycosides are a class of powerful antibiotics used for serious bacterial infections, typically given by IV in a hospital setting. The most commonly prescribed ones include gentamicin, tobramycin, amikacin, neomycin, kanamycin, and streptomycin. Unlike aspirin, the hearing damage from aminoglycosides is often permanent.
These drugs damage the delicate sensory hair cells inside the cochlea, the spiral-shaped structure in your inner ear that converts sound into nerve signals. Once those hair cells are destroyed, they don’t regenerate. The damage happens through a chain reaction: the drug triggers the production of harmful molecules called reactive oxygen species inside the cells, which ultimately causes the cells to self-destruct. This is why tinnitus from aminoglycosides frequently comes with measurable hearing loss, particularly in the high-frequency range.
Vancomycin, another antibiotic used for resistant infections like MRSA, can also cause hearing loss, especially in people with reduced kidney function. Azithromycin (the common “Z-pack” antibiotic) causes hearing changes in rare cases, and those changes are sometimes reversible, sometimes not.
Platinum-Based Chemotherapy
Cisplatin and carboplatin are among the most ototoxic medications in clinical use. A large prospective study found that nearly 39% of patients receiving cisplatin developed new tinnitus during treatment. Carboplatin was somewhat less damaging but still caused tinnitus in about 26% of patients. These are striking numbers, meaning roughly one in three people on cisplatin will develop ringing in their ears that wasn’t there before.
The hearing damage from platinum chemotherapy works through a similar mechanism to aminoglycosides: destruction of cochlear hair cells. Because these drugs are often given in repeated cycles over weeks or months, the damage tends to accumulate. Current guidelines from the American Academy of Audiology recommend a hearing test before treatment starts, regular monitoring during chemotherapy, and follow-up testing for at least several months afterward. For patients also receiving radiation to the head or neck, annual hearing checks are recommended for up to two years after treatment ends.
Loop Diuretics
Loop diuretics, commonly prescribed for heart failure, high blood pressure, and fluid retention, include furosemide (Lasix), bumetanide, and ethacrynic acid. On their own, these drugs typically cause only temporary hearing changes that resolve after the dose is lowered or the drug is stopped. Permanent damage from a loop diuretic alone is rare unless you’re taking very high doses or have significant kidney problems.
The real danger comes from combining loop diuretics with other ototoxic drugs. When high doses of furosemide are given alongside aminoglycosides like gentamicin or chemotherapy drugs like cisplatin, the combination can cause significant hair cell destruction and permanent hearing loss. This is more than additive: the diuretic appears to make the inner ear more vulnerable to the other drug’s toxic effects. If you’re prescribed a loop diuretic alongside any of the medications mentioned in this article, that combination warrants a conversation about hearing monitoring.
Antidepressants
Tinnitus shows up as a reported side effect across several classes of antidepressants, though the risk is generally lower than with the drug categories above. Tricyclic antidepressants like amitriptyline and nortriptyline are among the most commonly cited. SSRIs such as fluoxetine and paroxetine, along with other antidepressants like trazodone, have also been associated with tinnitus in some patients.
Interestingly, some of these same medications are occasionally prescribed to help manage tinnitus-related distress, which makes the picture complicated. The relationship between antidepressants and tinnitus can go both directions. Benzodiazepines (anti-anxiety medications like diazepam) present another wrinkle: tinnitus has been documented as a withdrawal symptom after long-term use, persisting for an extended period even after the drug is stopped.
Quinine and Antimalarials
Quinine, used to treat malaria and sometimes prescribed for leg cramps, can cause temporary hearing loss and tinnitus. Its synthetic substitutes carry the same risk. The effect is typically reversible once the medication is discontinued, but it can be alarming while it lasts. Tonic water contains small amounts of quinine, far below therapeutic doses, so it’s unlikely to cause problems for most people.
Why Kidney Function Matters
Your kidneys play a central role in determining how vulnerable you are to drug-induced tinnitus. Most ototoxic medications are cleared from the body through the kidneys. When kidney function is impaired, these drugs linger in your bloodstream at higher concentrations for longer periods, increasing their exposure to the inner ear. People with chronic kidney disease already have higher rates of hearing impairment than the general population, even before taking any ototoxic medication.
The connection between the kidneys and the inner ear runs surprisingly deep. The hair cells in your cochlea and the cells lining the kidney’s filtration tubes share a similar vulnerability to certain types of chemical damage, particularly from aminoglycosides and loop diuretics. Both cell types are sensitive to the same toxic pathways involving iron-related damage and disruption of ion transport. This is one reason why signs of kidney stress in lab work can sometimes predict hearing problems down the line.
Age compounds the risk. Older adults are more likely to have reduced kidney function, often without knowing it, and are also more likely to be taking multiple medications that can interact. The combination of an aminoglycoside with a loop diuretic in someone with compromised kidneys represents one of the highest-risk scenarios for permanent hearing damage.
Temporary vs. Permanent Tinnitus
The reversibility of drug-induced tinnitus depends almost entirely on whether the underlying hair cells have been destroyed. Aspirin, loop diuretics, and quinine typically cause functional changes in the inner ear that resolve once the drug clears your system. The hair cells are still intact; they were just temporarily disrupted.
Aminoglycosides and platinum chemotherapy drugs, by contrast, kill hair cells outright. Once that happens, the tinnitus and hearing loss are likely permanent. The earlier the damage is caught, the more options you have, which is why hearing monitoring during treatment with these drugs is so important. Even a small shift in your ability to hear high-frequency sounds can be an early warning sign that damage is underway, giving your medical team a chance to adjust the treatment plan before the loss becomes severe.
