Black Box Warning (Boxed Warning)

A Boxed Warning is the FDA's strongest safety warning — it indicates serious or life-threatening risks identified during clinical trials or post-market surveillance. It does not mean the medication is unsafe for all patients; your prescriber weighs these risks against the benefits for your specific situation. Source: FDA-approved prescribing information.
