A case of depression with oral burning involved several medication changes, making attribution to one change uncertain.
The sequence of treatment
The report described a 57-year-old woman with depression, burning mouth symptoms, tinnitus, and persistent anxiety and insomnia. After partial response to duloxetine, vortioxetine was added to the existing duloxetine and clonazepam regimen. Over the following two weeks, duloxetine and clonazepam were gradually tapered while vortioxetine increased.
The authors reported disappearance of the burning-mouth symptoms and improvement in glossodynia. The medication sequence is important because introduction, dose increase, and withdrawal of other treatment overlapped.
One case cannot identify the counterfactual
The report cannot establish what would have happened if clonazepam had been continued, stopped alone, or never prescribed. Nor does it compare vortioxetine with clonazepam in a controlled way. Symptoms may change with time and with broader management of depression and anxiety.
For review, document which symptom changed, when, and in relation to each medicine. This paper supports a possible treatment observation in a complex presentation. It does not establish that clonazepam caused the syndrome or that its withdrawal independently produced recovery.
