What Are Pregnancy Categories C and D?Because the results of the study explained earlier have not been confirmed, the U.S. Food and Drug Administration (FDA) categorizes Accupril as a pregnancy Category C medicine for the first trimester and a pregnancy Category D medicine for the second and third trimesters.
The FDA uses a pregnancy category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category C is given to medicines that show side effects to the fetus in animal studies, but for which no human studies in pregnant women have been done.
Pregnancy Category D is given to medicines that have shown clear evidence of risk to the fetus in studies. It is a stronger warning than for pregnancy Category C medicines. Despite these warnings, a pregnancy Category C or D medicine may still be given to a pregnant woman if her healthcare provider believes that its benefits outweigh the possible risks to the unborn child.
