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.

 

Kapvay and Lactation

The active ingredient in Kapvay is excreted in human breast milk. Because of the possibility for adverse reactions in nursing infants from Kapvay, a choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.
