Warnings While Using This Medicine

  • If you are pregnant or breastfeeding, talk to your doctor before taking this medicine.
  • Make sure your doctor knows if you have any other medical problems, such as colitis, emphysema, asthma, hepatitis or other liver diseases, heart, lung, or blood disease, or stomach ulcer.
  • This medicine can be habit-forming. You should not use more than the prescribed amount.
  • If you have taken this medicine for several weeks, do not stop taking it suddenly without asking your doctor. You may need to take smaller and smaller doses before completely stopping this medicine.
  • This medicine may cause drowsiness. If it does, be careful while driving a car or using machinery.
  • This medicine may cause constipation. This is more common if you use it for a long time. Ask your doctor if you should also use a laxative to prevent and treat constipation.
  • 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.
