Protriptyline Pregnancy Warnings

Animal studies have failed to reveal evidence of adverse effects on reproduction. There are no adequate and well-controlled studies in pregnant women.

To monitor maternal-fetal outcomes of pregnant women exposed to antidepressant therapy, a National Pregnancy Registry for Antidepressants has been established. Healthcare providers are encouraged to prospectively register patients. For additional information:

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 decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D and X are being phased out.

This drug should be used during pregnancy only if the benefit outweighs the risk to the fetus.

US FDA pregnancy category Not Assigned

-Use in women of childbearing potential should be used if benefit outweighs hazards to the mother and fetus.
