Viloxazine Pregnancy Warnings

Not recommended unless the benefits outweigh the potential risk to the mother

US FDA pregnancy category: Not assigned

Risk Summary: Available data from case series in pregnant women taking this drug are insufficient to determine a drug-associated risk of major birth defects, miscarriage or adverse maternal outcomes; animal data suggests this drug may cause maternal harm.

Comments:
-This drug should be discontinued when pregnancy is recognized unless the benefits of therapy outweigh the potential risk to the mother.
-There is a pregnancy registry that monitors pregnancy outcomes in women exposed to this drug during pregnancy; healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or visiting online at www.womensmentalhealth.org/preg.

Animal data has shown oral administration of this drug to pregnant rats and mice during pregnancy and lactation caused maternal toxicities and deaths at doses approximately 2 and 1 times the maximum recommended human dose based on mg/m2, respectively. Offspring toxicities were observed at these maternally toxic doses. There are no controlled data in human pregnancy.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decision and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.
