Safety classification systems used in dermatological medication risk counseling of pregnant and lactating patients: a case for an evidence-based approach.

Many women of childbearing age use prescription and non-prescription medications. Therefore, patients need to be counseled regarding the potential teratogenicity of medications if they are, or could become, pregnant. In this editorial, the present authors will explain the three advantages of the evidence-based medicine system when compared with the US Food and Drug Administration system for medication risk classification in pregnancy. The present authors will also comment on medication use during lactation and provide resources on medication use during pregnancy and lactation for clinicians and their patients.
