Conclusion: The available evidence, limited to case reports, case series, a survey and one small cohort, thereby preventing causal inference and incidence or prevalence estimates due to the absence of denominator data, nonetheless indicates injuries with both aqueous and alcohol-based products, raising concern for a potentially compound-related, rather than vehicle-specific, risk. Clinicians should consider judicious use of octenidine, monitor closely, and consider the potential utility of patch testing for delayed allergic reactions. Priority needs include multicenter studies, standardized skin outcomes, detailed exposure reporting, and pharmacovigilance or registries.
