Chlorambucil and Pregnancy
Tell your doctor if you are pregnant or plan to become pregnant.
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.
This medication falls into category D. It has been shown that use of chlorambucil 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.
Chlorambucil and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed. It is not known if chlorambucil is excreted in human breast milk or if it will harm your nursing baby. Because this medication has the potential to harm your nursing baby, you and your doctor will need to decide whether you should stop nursing or disontinue the medication.

Your doctor may recommend a lower dosage if you have kidney or liver disease or if, during treatment, your blood counts drop too low.
