Trazodone can cause tinnitus, but it’s uncommon. In controlled clinical trials, ringing in the ears occurred in about 1.4% of patients taking the drug, and the FDA lists tinnitus as a recognized adverse reaction on the official trazodone label. For most people taking trazodone for sleep or depression, ear ringing never becomes an issue, but it’s a real possibility worth understanding if you’re noticing new sounds in your ears after starting the medication.
How Often Trazodone Causes Tinnitus
The 1.4% figure comes from controlled studies where patients on trazodone were compared to those on placebo. In the placebo groups, the reported rate of tinnitus was essentially zero, which suggests the drug itself is responsible rather than some unrelated factor. To put that in perspective, roughly 1 in 70 people taking trazodone in those trials reported ringing in their ears.
Antidepressants as a class actually cause tinnitus less often than several other common medication types. Aspirin, anti-inflammatory painkillers like ibuprofen, and certain antibiotics are more frequently linked to ear ringing. So while trazodone carries this risk, it’s relatively low compared to medications many people take without a second thought.
Why Trazodone May Affect Your Hearing
Trazodone works primarily by blocking certain serotonin receptors in the brain and preventing serotonin from being reabsorbed after it’s released. Serotonin doesn’t just regulate mood and sleep. It also plays a role in how your brain processes sound signals. The auditory system has serotonin receptors, and when a drug changes how serotonin behaves throughout the nervous system, it can alter the way your brain interprets signals from the inner ear. In some people, this shows up as a persistent ringing, buzzing, or hissing sound that isn’t coming from any external source.
The exact chain of events from taking a trazodone tablet to hearing a ringing sound isn’t fully mapped out. What is clear is that the connection exists and that it’s pharmacological, meaning it’s tied to the drug’s chemical action rather than to physical damage in the ear itself. That distinction matters because drug-related tinnitus is more likely to resolve once the medication is adjusted or stopped.
Dose and Timing Considerations
Trazodone is prescribed across a wide dosage range. For insomnia, doses typically fall between 25 and 100 mg at bedtime. For depression, doses can climb to 300 mg or higher. The FDA labeling doesn’t break down tinnitus rates by dose level, so there’s no published threshold below which the risk drops to zero. However, drug side effects are generally dose-dependent: lower doses expose the brain to less of the active compound, which tends to mean a lower chance of side effects overall.
If you’re taking trazodone at a low dose for sleep and develop ringing in your ears, the timing of onset relative to when you started the medication (or when your dose changed) is the most useful clue. Tinnitus that appears within days or weeks of starting trazodone, or shortly after a dose increase, is more likely to be drug-related than ringing that develops months later with no dosage change.
What Happens if You Stop or Switch
For many people, tinnitus caused by a medication fades after the drug is discontinued or the dose is reduced. Trazodone has a relatively short half-life, meaning it clears your system faster than some other antidepressants, which can work in your favor if the ringing is drug-related.
There’s an important nuance here, though. Some reports describe tinnitus appearing or returning when an antidepressant is stopped, not just when it’s started. This can happen because the underlying condition the antidepressant was treating (depression or anxiety) itself influences how the brain processes sound. Stress and mood disorders are independent risk factors for tinnitus, so removing a medication that was managing those conditions can sometimes unmask or worsen ear ringing. This makes it tricky to sort out cause and effect without careful attention to timing.
Switching to a different medication is a practical option if trazodone seems to be the culprit. Not all antidepressants carry the same auditory side effect profile, and a different drug may provide the same benefits for sleep or mood without triggering tinnitus.
Why Early Attention Matters
Tinnitus that’s caught and addressed early tends to respond better than tinnitus that’s been present for months or years. When ringing persists for a long time, the brain can undergo changes that essentially “learn” the sound, making it harder to reverse even after the original cause is removed. Researchers describe this as centralization: the tinnitus signal gets wired into the brain’s sound-processing networks and becomes self-sustaining.
This is why paying attention to new ear ringing shortly after starting trazodone is worthwhile. If the sound is faint and you brush it off for six months before mentioning it, it may be harder to treat than if you flag it within the first few weeks. The practical takeaway is simple: if you notice ringing, buzzing, or any new persistent sound in your ears after starting or adjusting trazodone, bring it up at your next appointment rather than waiting to see if it resolves on its own.
Other Medications That Affect Tinnitus Risk
If you’re taking trazodone alongside other drugs, the combination may increase your risk more than trazodone alone. Aspirin at moderate to high doses, nonsteroidal anti-inflammatory drugs (like ibuprofen or naproxen), and certain antibiotics are all more commonly associated with tinnitus than antidepressants are. Loop diuretics, sometimes prescribed for blood pressure or swelling, can also affect the inner ear. When multiple medications with tinnitus potential are combined, the effects can stack.
Reviewing your full medication list is a useful step if you’re trying to figure out what’s causing new ear ringing. Trazodone may be contributing, but it may not be the only factor, especially if you’re also regularly taking pain relievers or other drugs known to affect hearing.
