Key points
- Tinnitus is prevalent health condition without a single effective
treatment.
- Betahistine is one of the most used empirical treatments for tinnitus,
without reliable scientific support.
- This randomized clinical trial is the first reliable study to test
betahistine use for this purpose.
- Our results reveal that this drug is ineffective for primary tinnitus
in adults, therefore, its large-scale use is likely to be of no
benefit to patients.
- We believe that this result can avoid the negative impact of the use
of ineffective treatments by these patients.
