Paliperidone and pregnancy-an evaluation of the German Embryotox database.

ABSTRACT

Schizophrenic or schizoaffective disorders often occur in early adulthood and thus affect women of childbearing age. For paliperidone information about reproductive safety is wanting. Therefore, we evaluated data from the German Embryotox pharmacovigilance institute regarding paliperidone therapy during pregnancy. The German Embryotox pharmacovigilance institute offers risk assessment on drug use in pregnancy and documents the outcome of more than 3500 drug-exposed pregnancies per year. In our study, we analyze the outcome of all pregnancies with paliperidone exposure, which have been assessed by our institute between January 2007 and June 2016. Of the 17 prospectively assessed pregnancies, 14 resulted in 15 live-born children (including one pair of twins). None of the infants presented with major congenital malformations. There were two spontaneous abortions at gestational weeks 6 and 11, respectively, and one elective termination due to personal reasons. Sixty-five percent of the pregnant women smoked cigarettes throughout pregnancy, 17% consumed alcohol. Five children were born prematurely (< 37 gestational weeks) and four were small for gestational age, each group including the twins. The results of our study suggest that paliperidone may be administered during pregnancy. The increased rate of prematurity and small for gestational age children can at least partially be explained by other risk factors. Psychiatric and obstetric close monitoring as well as additional medical and social support are recommended to ensure a healthy pregnancy course in patients with a severe mental illness.
