Klebsiella Sepsis reporting signals

Last recalculated 2026-09-14T18:28:35.993900+00:00 · 1,114 reports · 82 co-occurring drugs

As of the last recalculation, Klebsiella Sepsis appears in 1,114 FAERS reports alongside 82 co-occurring drug terms. The strongest observed disproportionality signal is FLUDARABINE PHOSPHATE (PRR 56.1).

Important: FAERS is a spontaneous, voluntary, unverified reporting system. PRR and ROR identify reporting patterns for investigation; they are not incidence rates and do not establish causation.
