Understanding Pregnancy Drug Categories
When it comes to taking medication during pregnancy, both patients and healthcare providers must carefully weigh the potential benefits against any possible risks to the developing baby. One of the tools traditionally used to guide this decision-making process is the FDA’s pregnancy drug classification system. While this system is now being phased out in favor of more detailed labeling through the Pregnancy and Lactation Labeling Rule (PLLR), the original categories—A, B, C, D, and X—are still widely referenced in clinical settings and patient resources.
These categories provide a general framework for understanding the level of evidence behind a medication’s safety during pregnancy, ranging from drugs with strong evidence of safety to those known to cause harm. Though not perfect, this classification system continues to serve as a helpful guide for discussing medication risks and making informed treatment decisions—especially for psychiatric medications, where balancing maternal mental health with fetal development is a complex but essential task.
In the sections below, you’ll find a breakdown of the historical FDA pregnancy categories and examples of commonly prescribed psychiatric medications within each class.
Category | What It Means |
---|---|
A | Human studies show no risk to the fetus. |
B | Animal studies show no risk, or animal studies show risk but human studies do not. |
C | Animal studies show risk, and there are no adequate human studies. May be used if benefits outweigh risks. |
D | Evidence of fetal risk exists, but medication may be necessary for serious conditions. |
X | Proven risk to fetus; use is contraindicated in pregnancy. |
