Category A

No observed risk in animal studies (adequate human studies are lacking, but animal studies indicated no harm to the fetus).

Category B

Risk undetermined . There are no satisfactory human studies, but animal studies have shown potential harm to the fetus; the benefits of the drug may outweigh the risks.

Category C

Risk confirmed (studies in pregnant women have demonstrated harm to the fetus; the benefits of the drug may outweigh the risks ).
