Galactorrhea and hyperprolactinemia in schizophrenic patients on neuroleptics: frequency and etiology

Abstract

The frequency of galactorrhea and the subjective response to it were investigated in 150 schizophrenic patients. The incidence rate was 14% and the prevalence rate 19%. The latency periods between start of neuroleptic medication and manifestation of galactorrhea were subject to substantial scatter, as were the prolactin values. Patients who had undergone neuroleptic relapse prevention prior to the index episode and/or had been pregnant were affected significantly more frequently by galactorrhea.
