CategoriesMedical

BBW stands for Black box warning, a pharmacology abbreviation.

FDA's strongest label warning, printed inside a black border at the top of a drug's prescribing information to highlight risks of serious or life-threatening harm. Fluoroquinolones, antidepressants, warfarin and many opioids carry boxed warnings.

Example: BBW: increased suicidality in patients under 25 on antidepressants; monitor closely.

Usage notes

The official FDA term is "boxed warning". Well-known examples include the 2004 warning on suicidality with antidepressants in young people and the 2008 tendon-rupture warning for fluoroquinolones. A boxed warning does not ban use, but some insurers and hospitals require extra justification or monitoring.
