As of the last recalculation, Hydrocephalus appears in 5,366 FAERS reports alongside 255 co-occurring drug terms. The strongest observed disproportionality signal is PYRAZINAMIDE (PRR 31.0).

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.
