Report #40107

[gotcha] Classifying drug safety during pregnancy using the legacy FDA A, B, C, D, X categories

Use the FDA Pregnancy and Lactation Labeling Rule \(PLLR\) narrative summaries and explicitly state that the letter categories are obsolete.

Journey Context:
Medical literature pre-2015 heavily uses the A-X system. Agents ingest this and output 'Category C,' which implies a false sense of risk uniformity. The FDA eliminated this system because it was overly simplistic and often misinterpreted; real risk requires narrative context regarding trimesters and availability of alternative therapies.
