Clonazepam for Tinnitus Management

Mechanism and Efficacy

Clonazepam, a long-acting benzodiazepine, promotes GABAergic inhibition by increasing the frequency of chloride channel opening, which may reduce central nervous system hyperexcitability potentially associated with tinnitus 3
Benzodiazepines like clonazepam may reduce the subjective sensation of tinnitus by addressing anxiety and sleep disturbances that often accompany and exacerbate tinnitus perception 4

The American Academy of Otolaryngology-Head and Neck Surgery explicitly does not recommend anxiolytics (including benzodiazepines) for primary treatment of persistent tinnitus due to insufficient evidence and potential side effects 1, 2
Cognitive Behavioral Therapy (CBT) has the strongest evidence for improving quality of life in patients with persistent, bothersome tinnitus 1, 2
The American Academy of Otolaryngology-Head and Neck Surgery recommends hearing aid evaluation for patients with hearing loss and tinnitus, even if the hearing loss is mild or unilateral 1, 2

Common adverse effects of clonazepam include daytime sleepiness, dizziness, and postural instability, which can be particularly problematic in elderly patients 3
Long-term use of clonazepam carries risks of tolerance, dependence, and cognitive impairment 4
The American Geriatrics Society lists clonazepam as a potentially inappropriate medication in older adults 3

Clonazepam may be considered when tinnitus is accompanied by severe anxiety or depression that significantly impacts quality of life, but should not be the primary treatment for tinnitus itself 5, 6
For patients with both REM sleep behavior disorder and tinnitus, clonazepam might address both conditions, as it is recommended for REM sleep behavior disorder 7, 8, 3
