The safety of psychotropic drug use during pregnancy: a review

A substantial number of women of childbearing age are prescribed psychotropic drugs, and because nearly 50% of pregnancies are unplanned, many women are still taking them upon becoming pregnant. This article reviews the various classes of psychotropic drugs that are commonly used to treat psychiatric disorders--antidepressants, benzodiazepines, antipsychotics, antiepileptics, lithium and monoamine oxidase (MAO) inhibitors--in terms of their safety during pregnancy. Evidence-based information from epidemiologic studies indicates that most psychotropic drugs are relatively safe for use during pregnancy. There is also an increasingly large body of evidence-based information in the literature indicating that it may be more harmful to both the mother and her baby if she is not treated appropriately when suffering from a severe psychiatric disorder. Therefore, it is important for women with psychiatric disorders and their healthcare providers to have access to evidenced-based information about the safety of these drugs when taken during pregnancy to ensure that women make an informed decision as to whether they should continue with the pharmacotherapy they have been using to treat their condition.
