FDA drug labeling: rich resources to facilitate precision medicine, drug safety, and regulatory science

•FDA drug labeling contains information about drug efficacy, safety, and more.•FDALabel is a web-based database application of ∼80 000 drug labeling documents.•FDALabel supports customizable searches with an easy navigation interface.•Use cases for ADR study and pharmacogenomics were illustrated.

Here, we provide a concise overview of US Food and Drug Administration (FDA) drug labeling, which details drug products, drug-drug interactions, adverse drug reactions (ADRs), and more. Labeling data have been collected over several decades by the FDA and are an important resource for regulatory research and decision making. However, navigating through this data is challenging. To aid such navigation, the FDALabel database was developed, which contains a set of approximately 80 000 labeling data. The full-text searching capability of FDALabel and querying based on any combination of specific sections, document types, market categories, market date, and other labeling information makes it a powerful and attractive tool for a variety of applications. Here, we illustrate the utility of FDALabel using case scenarios in pharmacogenomics biomarkers and ADR studies.
