Can Antidepressants Make Tinnitus Worse? New Research Explains Why

Date Published: September 7, 2026
For years, patients have told me their tinnitus became worse after starting an antidepressant. Until recently, the explanation was incomplete.
A 2026 study published in the Proceedings of the National Academy of Sciences identified a specific brain circuit linking serotonin activity to the auditory system. That finding may help explain why some patients notice louder or more intrusive tinnitus after starting or changing an SSRI.
This does not mean antidepressants are unsafe or that patients should stop taking them. Depression and anxiety are serious, and treatment matters. But it does mean medication changes should be part of a complete tinnitus evaluation.

Quick Answer
Yes, antidepressants can make tinnitus worse for some people.
A 2026 study published in the Proceedings of the National Academy of Sciences identified a direct pathway between serotonin-producing neurons in the brainstem and a key part of the auditory system. When researchers activated that pathway in mice, the animals showed behavior consistent with tinnitus.
The finding helps explain why some patients notice louder or more intrusive tinnitus after starting an SSRI or changing the dose. An Oregon Health & Science University summary of the research also emphasizes that patient reports of medication-related tinnitus changes deserve to be taken seriously.
This does not mean you should stop taking an antidepressant. Depression and anxiety are serious, and stopping medication abruptly can create other problems. If your tinnitus changed after starting or adjusting an antidepressant, document the timeline and discuss it with your prescribing physician.
The Question Patients Are Actually Asking
I have been hearing some version of this question more often:
“My tinnitus got worse after I started my antidepressant. Could the medication be related?”
Most patients are not asking out of curiosity. They have noticed a real change and are trying to understand whether the timing matters.
The harder question is what to do when the medication is helping depression or anxiety, but the tinnitus seems louder or more intrusive.
For years, the best answer was cautious: the connection was possible, the mechanism was not well understood, and the issue should be discussed with the prescribing physician.
That answer was honest, but incomplete.
The new research does not settle every question. However, it gives patients and clinicians a much clearer biological reason to take the medication timeline seriously.
What the 2026 PNAS Study Found
A 2026 study published in the Proceedings of the National Academy of Sciences identified a direct connection between the brain’s serotonin system and the auditory system.
The researchers focused on two areas of the brain: the dorsal raphe nucleus, which produces serotonin, and the dorsal cochlear nucleus, one of the first places the brain processes sound.
In plain language, they found a direct line between a part of the brain involved in mood regulation and a part involved in hearing.
When researchers activated that pathway in mice, the animals showed behavior consistent with tinnitus. An OHSU summary of the study explains that the stimulation changed activity in the auditory system and produced behavior suggesting the mice were experiencing a phantom sound.
When the researchers selectively quieted the same pathway, the tinnitus-like behavior was reduced.
That finding matters because it gives researchers a specific circuit to study. In the future, it may be possible to reduce the auditory side effects of serotonin-based medications without interfering with their benefits for depression or anxiety.
That is still years away from clinical use. For now, the study gives patients and clinicians a stronger biological reason to take medication-related tinnitus changes seriously.
What We Knew Before This Study
This study was done in mice, not humans. That distinction matters.
The auditory system in mice shares important features with the human auditory system, but the findings still need to be confirmed in people. The study does not prove that SSRIs cause tinnitus in every patient.
What it does provide is a plausible biological explanation for a pattern clinicians and patients have reported for years.
Tinnitus has been reported in connection with several SSRIs, including sertraline, fluoxetine, and paroxetine. However, those reports do not establish that the medication was the cause in every case.
The American Academy of Otolaryngology–Head and Neck Surgery tinnitus guideline recommends against prescribing antidepressants as a routine treatment for persistent, bothersome tinnitus.
That does not mean antidepressants should never be used in someone who has tinnitus. They may still be important for treating depression or anxiety. The point is that tinnitus changes should be recognized, documented, and discussed rather than dismissed.
The evidence had been pointing toward a connection for years. The 2026 PNAS study helps explain how it may happen.
A complete tinnitus evaluation should also include a careful medication history. Unfortunately, many evaluations focus on hearing thresholds and skip the timing of medication changes altogether.
That leaves the audiologist treating one part of the problem while the prescribing physician treats another, with little communication between them.

When Tinnitus Gets Worse After a Dose Change
A patient came to see me about 18 months ago. He was in his early 50s and had been dealing with moderate tinnitus in both ears for about three years. He had also been managing depression for most of his adult life and was taking an SSRI.
For a while, the tinnitus had been fairly stable. Then his psychiatrist increased the dose.
Soon after that change, the ringing became much more intrusive. It was louder at night and harder to ignore during the day.
He mentioned it during a primary care visit and was told it was probably stress.
By the time he came to see me, he almost left the medication change out of the conversation. He did not think it mattered, and after being dismissed once, he was not sure it was worth bringing up again.
We reviewed his medication timeline alongside the history of his tinnitus. The pattern was hard to ignore: the increase in tinnitus closely followed the dose change.
I was not in a position to change his psychiatric medication. That decision belonged to his prescribing physician. What I could do was document the timing clearly and communicate it directly.
That changed the conversation.
His psychiatrist adjusted the treatment plan. A few months later, he described the tinnitus as “back in the background” and much easier to ignore.
That was not a cure. It was a reminder that medication history belongs in a complete tinnitus evaluation.

What to Do If Your Tinnitus Changed After Starting an Antidepressant
This research is not a reason to stop taking an antidepressant on your own.
Depression and anxiety are serious conditions, and stopping medication abruptly can cause withdrawal symptoms or make those conditions worse. Any medication change should be made with the prescribing physician.
What has changed is that patients now have stronger evidence to support the conversation.
If your tinnitus became louder after starting an SSRI or increasing the dose, document the timeline as clearly as you can:
- Write down when the medication was started or changed.
- Note when the tinnitus became louder or more intrusive.
- Record any other changes around the same time, such as illness, stress, poor sleep, or noise exposure.
- Bring that information to the physician who prescribed the medication.
- Ask whether another dose, medication, or treatment approach may be appropriate for you.
The 2026 PNAS study does not prove that an antidepressant caused your tinnitus. It does show that there is a biologically plausible pathway linking serotonin activity with the auditory system.
An OHSU summary of the research also emphasizes the importance of taking patient reports seriously rather than dismissing the timing as coincidence or stress.
A complete tinnitus evaluation should include a full medication history. At Timpanogos Hearing & Tinnitus, we review what you are taking, when it was started, when the dose changed, and whether those changes line up with your tinnitus history.

Getting a Complete Tinnitus Evaluation
If your tinnitus changed after starting or adjusting an antidepressant, the medication timeline should be part of the evaluation.
A complete tinnitus assessment should include more than a standard hearing test. It should also review:
- Current medications
- When each medication was started
- Any recent dose changes
- When the tinnitus changed
- Sleep, stress, illness, and noise exposure
- Hearing ability in background noise
- How much the tinnitus affects daily life
At Timpanogos Hearing & Tinnitus, we review the full clinical picture instead of looking only at hearing thresholds. That helps us identify patterns that may otherwise be missed and gives the prescribing physician clearer information to work with.
Our clinics in American Fork, Spanish Fork, and South Jordan serve patients across Utah County and the southern Salt Lake Valley.

What This Research Still Doesn’t Tell Us
This study identified a specific serotonin pathway that may help explain why tinnitus changes for some people taking antidepressants. It did not answer every clinical question.
We still do not know whether all SSRIs carry the same risk. Different medications affect serotonin in different ways, so one drug may influence the auditory system more than another.
The study also does not explain why some people develop tinnitus or notice a worsening of symptoms while others do not. Hearing history, existing inner-ear damage, medication dose, genetics, and individual sensitivity may all play a role.
It is also too early to apply these findings broadly to other antidepressant classes, such as SNRIs or tricyclic antidepressants. The 2026 PNAS study focused on a specific serotonin pathway.
Most importantly, this research was done in mice. The findings are biologically meaningful, but they still need to be confirmed in human studies.
What the study does support is a more careful clinical approach. If tinnitus changes after a medication is started or adjusted, the timeline should be documented and discussed rather than dismissed.

FAQ
Tinnitus has been reported after starting some antidepressants, including several SSRIs. A 2026 study identified a serotonin pathway that may help explain how this can happen.
That does not mean everyone who takes an antidepressant will develop tinnitus. If the ringing began soon after starting a medication or changing the dose, document the timing and discuss it with the prescribing physician. to start?
No. Do not stop an antidepressant or change the dose without speaking with the clinician who prescribed it.
Stopping suddenly can cause withdrawal symptoms and may worsen depression or anxiety. Instead, write down when the medication changed, when the tinnitus changed, and any other factors that may have played a role. Bring that information to your prescriber.
Probably not. The current research focuses on a serotonin pathway that is especially relevant to SSRIs. Different antidepressants affect serotonin and other brain chemicals in different ways.
Researchers have not yet compared every medication class or determined which drugs are most likely to affect tinnitus.
Not completely. Patient reports and clinical literature have suggested a connection for years, but the 2026 study used mice to identify the specific brain pathway.
The findings provide a strong biological explanation, but direct human studies are still needed. For now, medication-related tinnitus changes should be taken seriously without assuming the medication is automatically the cause.
