Assessing National Trends and Perceived Safety of Off-Label Ciprofloxacin-Dexamethasone Use by Pediatric Otolaryngologists.

Abstract

Off-label use of Ciprodex® (ciprofloxacin-dexamethasone: CPD), an antibiotic-steroid combination solution, in the airway has been reported by pediatric otolaryngologists with anecdotal success. We examined national trends regarding off-label CPD use including prevalence, common indications, prescriber patterns, adverse events, and accessibility. 15-item cross-sectional survey was distributed to American Society of Pediatric Otolaryngology members from January-April 2022. Univariate analyses were performed to compare responses for users of off-label CPD versus non-users. Ease of access was compared across geographies and practice types using multivariate logistic regressions. Of the 163 complete responses (26.6% response rate), 156 (95.7%) reported using off-label CPD. Most common indications for off-label CPD were tracheal granulation (87.8%, n = 137) and choanal atresia (82.1%, n = 128). Ease of access was significantly increased in the Midwest (OR:18.79, 95%CI:3.63-1.24, p = 0.001) and West (OR:29.92, 95%CI:3.55-682.00, p = 0.006). Ease of access was significantly lower at tertiary referral centers (OR:0.11, 95%CI:0.01-0.64, p = 0.041) and private practices (OR:0.04, 95%CI:0.002-0.33, p = 0.009) compared to academic free-standing children's hospitals. Two-thirds of respondents reported feeling "Very Comfortable" with the safety profile of off-label CPD; 99.4% (n = 156) felt that the benefits outweighed the risks of off-label use. Seven respondents (4.5%) reported adverse events (e.g., local allergic reaction, cushingoid symptoms) from off-label use. Our findings (26.6% response rate) suggest that off-label CPD is commonly used by pediatric otolaryngologists, many of whom reported feeling that the benefits of off-label CPD outweigh the risks. Our results establish a baseline for future efforts to assess the efficacy and safety of off-label CPD and to improve its accessibility. V Laryngoscope, 134:2922-2930, 2024.
