Category  Interpretation
A Controlled studies show no risk
Adequate, well-controlled studies in pregnant women have failed to demonstrate risk to the fetus
B No evidence of risk in humans
Either animal findings show risk (but human findings do not) or, if no adequate human studies have been done, animal findings are negative.
C Risk cannot be ruled out
Human studies are lacking and animal studies are either positive for fetal risk or lacking as well. However, potential benefits may justify the potential risk.
D Positive evidence of risk
Investigational or postmarketing data show risk to fetus. Nevertheless, potential benefits may outweight the risk.
X Contraindicated in pregnancy
Studies in animals or humans, or investigational or postmarketing reports have shown fetal risk which clearly outweighs any possible benefit to the patient. |
