Special information if you are pregnant or breastfeeding

The effects of Vicodin in pregnancy have not been adequately studied. Do not take Vicodin if you are pregnant or plan to become pregnant unless you are directed to do so by your doctor. Drug dependence occurs in newborns when the mother has taken Vicodin regularly prior to delivery. If you take it shortly before delivery, the baby's breathing may be slowed. Acetaminophen does, and hydrocodone may, appear in breast milk and could affect a nursing infant. If Vicodin is essential to your health, your doctor may advise you to discontinue breastfeeding your baby until your treatment is finished.
