Acetaminophen and Infusion Related Reaction: is the FAERS signal real?
A written Bradford Hill assessment of one drug–event pair. The grade is a judgement about the signal, not a statement that this drug causes this event in any one person; FAERS counts are reports, not rates.
Acetaminophen ↔ Infusion Related Reaction
n=13,947 co-reports · PRR 12.4 · ROR 12.8
Fludarabine is a purine nucleoside analogue for CLL. Myelosuppression is expected: DNA synthesis inhibition. 610 co-reports (PRR 14.8). Boxed warning.
Boxed warning: fludarabine label (myelosuppression).
