Conclusion
We report the detailed drug allergy landscape of the Hong Kong population. Excipient registries are ineffective in countries without mandatory excipient listings . Contrary to traditional doagma, we identified a disproportionately higher incident drug allergy among middle-aged and older patients. Findings need to be confirmed by region-specific big data studies.
