Guillain-Barre Syndrome reporting signals

Last recalculated 2026-09-14T18:28:35.993900+00:00 · 4,760 reports · 180 co-occurring drugs

As of the last recalculation, Guillain-Barre Syndrome appears in 4,760 FAERS reports alongside 180 co-occurring drug terms. The strongest observed disproportionality signal is BUSULFAN (PRR 15.5).

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.
