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.

Make sure your doctor knows if you are also using another narcotic medicine (such as naltrexone, Nubain®, Stadol®, Revia®), or an MAO Inhibitor (Eldepryl®, Marplan®, Nardil®, Parnate®).

Make sure your doctor knows if you are using any medicines that make you sleepy (such as sleeping pills, cold and allergy medicine, narcotic pain relievers, or sedatives). Do not drink alcohol while you are using this medicine.
