Practice and Tools
Go to the source behind the question.
Product labeling, safety communications, approval documents, clinical guidelines, and published literature each answer a different kind of question.

Start with the source that fits yours, then check the product, population, source date, and limitations before applying what you find.
Product Labeling
Use current labeling when you need the FDA submitted prescribing information for a specific product. Confirm the product, formulation, and label date before relying on a section.
Drug Safety and Availability
Use FDA safety communications and related resources when evaluating a newly communicated risk, a safety action, a recall, or a shortage. A communication may not answer every patient specific question; review the underlying source and current clinical guidance.
Drug Approvals
An approval announcement is where clinical interpretation begins. Review the approved indication, the population studied, efficacy and safety findings, limitations, and the product specific approval materials before deciding what the approval means for practice.
Biomedical Literature
Use PubMed to locate studies, then evaluate design, population, comparator, outcomes, methods, and limitations rather than relying on the abstract.
Clinical Guidelines
Use the guideline issued by the professional or scientific organization responsible for the topic and confirm its publication or update date. Interpret recommendations within their intended population and evidence base.
Medication References
Start with the source that fits your question. Coverage and update timing differ, so confirm the product, population, reference period, and limits before applying the information.
DailyMed: Search labeling submitted to FDA and check the specific product and label date. DailyMed is not a complete inventory of every FDA-regulated product.
FDA drug safety and availability: Review safety communications and related availability information from the agency.
FDA novel drug approvals: Review CDER’s 2025 novel-drug list and follow the product-specific approval information. This is a dated reference, not a live list of every type of approval.
PubMed: Find biomedical literature, then assess the methods, population, and limitations of the underlying study.
Medication Reference Directory
For product-specific information, begin with current labeling and relevant safety communications. Verify the formulation and source date, and use an appropriate clinical reference for questions the label does not answer.
PharmD Hub links to authoritative sources. Access, coverage, and update schedules vary by source.
