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.

Kapvay falls into category C. No adequate studies have been done in pregnant women. Animal study results do not always equal that of human response. Kapvay should be used during pregnancy only if clearly needed. It is not known if Kapvay will harm your unborn baby.

Tell your doctor if you are breastfeeding or plan to breastfeed.
