potential benefits may warrant use of the drug in pregnant women despite potential
risks.

Category X drug ✅Studies in animals or humans have demonstrated fetal
abnormalities and/or there is positive evidence of human fetal risk based on adverse
reaction data from investigational or marketing experience, and the risks involved in use
of the drug in pregnant women clearly outweigh potential benefits.
