• Category C:

  • Animal studies demonstrate adverse effects on the fetus, with no adequate human studies available.
  • Benefits of the drug may be acceptable despite potential risks, or lacking animal reproduction studies and human data.

• Category D:

  • There is evidence of human fetal risk.
  • Potential benefits of the drug for pregnant women may justify risks.

• Category X:

  • Studies in animals or humans reveal fetal abnormalities or adverse reactions.
