Antipsychotic Therapy During Early and Late Pregnancy. A Systematic Review

Reviewed information was too limited to draw definite conclusions on structural teratogenicity of FGAs and SGAs. Both classes of drugs seem to be associated with an increased risk of neonatal complications. However, most SGAs appear to increase risk of gestational metabolic complications and babies large for gestational age and with mean birth weight significantly heavier as compared with those exposed to FGAs. These risks have been reported rarely with FGAs. Hence, the choice of the less harmful option in pregnancy should be limited to FGAs in drug-naive patients. When pregnancy occurs during antipsychotic treatment, the choice to continue the previous therapy should be preferred.
