Your child may experience constipation, drowsiness, or nausea and vomiting. You should always discuss these and other side effects with the doctor or nurse. These side effects can be treated. They are not a reason to stop giving your child the medicine. Alcohol also increases drowsiness and should not be taken with narcotic analgesics.
Prevention is the best approach to constipation.
It's important to keep track of your child's bowel movements, particularly if your child has had problems with constipation. Make sure that your child drinks plenty of liquids and eats high fiber foods like fruits and vegetables, whole wheat bread, bran cereal and bran muffins. Some of these products may require a prescription. First, it's important for the doctor to figure out if the nausea and vomiting are from the pain medication. If nausea is caused by the pain medication, it will usually go away in a few days.
