Abstract
OBJECTIVES: The aim of the study was to determine the absolute and relative safety of treatment with 2 concentrations of topical clonazepam solution (0.1 mg/mL, 0.5 mg/mL) for management of oral dysesthesia.
STUDY DESIGN: The study was a retrospective chart review of patients diagnosed with oral dysesthesia and managed with topical clonazepam solution (swish and spit) between 2008 and 2015. The relative safety of the 2 concentrations was evaluated in terms of occurrence of adverse drug reactions (ADRs) and occurrence of change to treatment plan secondary to ADRs.
RESULTS: For the study, 162 patients were included-84 patients in the 0.1 mg/mL cohort and 78 in the 0.5 mg/mL cohort, who were evaluated for a median follow-up period of 6 weeks. Thirty-eight (23%) patients developed ADRs. The most frequently reported ADR was sedation (62% of ADRs), followed by altered mental status and dizziness (7% each). Dose adjustments were required in 9 patients (6%) and treatment discontinuation in 13 (8%). ADRs were more frequently reported in the 0.5 mg/mL cohort, but no significant difference was found in terms of occurrence of ADRs, change to treatment plan secondary to ADRs, or types of ADRs (P > .05).
CONCLUSIONS: Treatment with topical clonazepam solution in either 0.5 mg/mL or 0.1 mg/mL concentration appears to be safe and well-tolerated. Future prospective studies are needed to confirm this finding.
