Do not give  Tylenol with Codeine #3 to anyone younger than 12 years old, or anyone under 18 who recently had surgery to remove the tonsils or adenoids.
Taking opioid medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use opioid medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Stop taking this medicine and call your doctor right away if you have skin redness or a rash that spreads and causes blistering and peeling.
Before taking this medicine
You should not use this medicine if you are allergic to acetaminophen or codeine, or if you have:
severe asthma or breathing problems; or
a blockage in your stomach or intestines.
In some people, codeine breaks down rapidly in the liver and reaches higher than normal levels in the body. This can cause dangerously slow breathing and may cause death.
Codeine is not approved for use by anyone younger than 12 years old.
Do not give this medicine to anyone younger than 18 years old who recently had surgery to remove the tonsils or adenoids.
Tell your doctor if you have ever had:
breathing problems, sleep apnea;
liver disease;
alcoholism or drug addiction;
urination problems;
kidney disease; or
problems with your pancreas, thyroid, or gallbladder.
If you use opioid medicine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on opioids may need medical treatment for several weeks.
Do not breastfeed. Codeine can pass into breast milk and cause drowsiness, breathing problems, or death in a nursing baby.
