When a mother is breastfeeding and takes codeine, there is a very small chance that this medicine could cause serious side effects in the baby. This is because codeine works differently in a few women, so their breastmilk contains too much medicine. If you take codeine, be alert for these signs of overdose in your nursing baby: sleeping more than usual, trouble breastfeeding, trouble breathing, or being limp and weak. Call the baby's doctor right away if you think there is a problem. If you cannot talk to the doctor, take the baby to the emergency room or call 911.
