Valchlor and Pregnancy

The FDA categorizes medications based on safety for use during pregnancy. Five categories -A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Valchlor falls into category D. It has been shown that use of Valchlor in pregnant women caused some babies to be born with problems.  However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby. Please refer to the FDA warning section for more information.
