Which category of drugs is contraindicated for use in pregnancy and potentially pregnant women?

Category X drugs are definitively contraindicated for use in pregnancy and in women who may become pregnant. This classification indicates that studies in animals or humans have demonstrated fetal abnormalities, or there is positive evidence of human fetal risk based on adverse reaction data. The risks involved in using these medications during pregnancy clearly outweigh any potential benefits, making them dangerous for both the mother and the developing fetus.

This classification serves as a critical guideline for health care providers to avoid prescribing certain medications to pregnant individuals, ensuring their safety and that of the unborn child. In contrast, Category A drugs are considered safe, Category B drugs may be used with caution, and Category C drugs have potential risks that need careful consideration. Understanding these categories aids in making informed decisions regarding medication use in pregnant and potentially pregnant women.
