    Relative Benefit to MotherSide Effects in Pregnant PatientsPotential Risk to FetusStructural or Visceral AbnormalitiesAltered Physiologic Function of Nursing Baby

  • TERATOGEN

    An Agent That By Acting During the Embryonic or Fetal Period Produces Morphologic or Functional Malformations That Become Apparent Postnatal

  • SOURCES

    Case Reports

    Individual Experience

    Animal Studies

  • SYSTEMIC EFFECTS

    Oral Medications

    Topical MedicationsAbsorbed Systemically by Drainage Through Nasopharyngeal MucosaSecreted in Breast Milk

  • FDA CATEGORIES FOR DRUG USE IN PREGNANCYCategory A--- Adequate and well controlled studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).Category B--- Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women.Category C--- Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.Category D--- There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.Category X--- 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.
