Can bupropion cause tinnitus?
Bupropion has been reported to cause hearing-related side effects in some people, including tinnitus (ringing in the ears). The issue is uncommon, but it’s plausible given how bupropion can affect neurotransmitter signaling and has known effects on the ear/hearing in product safety information and adverse-event reports. [1]
If you started bupropion recently and tinnitus began soon after (or got worse after a dose increase), the timing supports bupropion as a possible trigger.
What should you do if tinnitus starts after starting bupropion?
A practical approach is to treat new tinnitus as a potentially medication-related symptom until proven otherwise:
- Contact the prescribing clinician promptly, especially if tinnitus is new, worsening, or occurs with other symptoms.
- Ask whether to adjust the dose, switch formulations (immediate vs. extended release), or stop the drug.
- Avoid driving or using hazardous machinery if you also notice dizziness or significant hearing changes.
Do not stop the medication abruptly without medical advice, but clinicians commonly consider changing the regimen if tinnitus appears to be linked.
When is tinnitus more urgent (what symptoms matter)?
Tinnitus is more concerning if it comes with signs of possible hearing injury or inner-ear problems, such as:
- Sudden hearing loss (over hours to a day)
- One-sided tinnitus with noticeable hearing decline
- Severe vertigo, new neurologic symptoms, or ear pain/discharge
Those scenarios warrant urgent evaluation (same day or emergency care depending on severity), because some causes of sudden hearing changes can be time-sensitive.
Does bupropion worsen tinnitus in people who already have it?
If you already have tinnitus, bupropion could potentially make it louder or more noticeable in some cases. If your baseline tinnitus changes after starting bupropion, tell your clinician. Dose timing matters: many medication-related side effects track with when levels peak.
What else can cause tinnitus besides bupropion?
Even if you suspect bupropion, tinnitus has many other causes, including noise exposure, earwax blockage, ear infections, eustachian tube dysfunction, migraine, medication effects from other drugs, and age-related hearing changes. A medication review is helpful because multiple agents can contribute to tinnitus.
What alternatives might be considered if bupropion is the cause?
If bupropion is suspected, clinicians may consider switching to another antidepressant or smoking-cessation option depending on why you’re taking it. The best alternative depends on your diagnosis, prior responses, and risk factors. Your prescriber can weigh options while monitoring for symptom change.
