Pregnancy Risk Categories defined:
A: Studies in pregnant women failed to show a risk to the fetus in the first
trimester - with no evidence of risk in the later trimesters.
B: Animals studies indicate no adverse effect to the fetus, but there are no adequate,
clinical studies in pregnant women.
C: Animal studies have shown an adverse effect on the fetus, but there are no adequate,
clinical studies in humans. Despite potential risks, the drug may be useful in pregnant
women.
D: There is evidence of risk to the human fetus, but the potential benefits of use in
pregnant women may be acceptable, despite potential risks.

indicate evidence of fetal risk. Warning: the risks involved clearly outweigh any
potential benefit from using the drug in pregnant women, regardless of trimester.

risks or benefits).
