• Tell all of your child’s health care providers that your child is taking this drug. This includes your child’s doctors, nurses, pharmacists, and dentists.
• Have your child avoid tasks or actions that call for alertness until you see how this drug affects your child. These are things like riding a bike, playing sports, or using items such as scissors, lawnmowers, electric scooters, toy cars, or motorized vehicles.
• To lower the chance of feeling dizzy or passing out, have your child rise slowly if your child has been sitting or lying down. Have your child be careful going up and down stairs.
• Do not give more than the doctor told you to give. Do not give more often or for longer than you were told. Doing any of these things may raise the chance of severe side effects.
• Do not give this drug with other strong pain drugs or pain patches without talking to your child’s doctor first.

• This drug may affect certain lab tests. Tell all of your child’s health care providers and lab workers that your child takes this drug.
• If your child has been taking this drug for a long time or at high doses, it may not work as well and your child may need higher doses to get the same effect. This is known as tolerance. Call the doctor if this drug stops working well. Do not give more than ordered.
• Long-term or regular use of opioid drugs like this drug may lead to dependence. Lowering the dose or stopping this drug all of a sudden may cause a greater risk of withdrawal or other severe problems. Talk to your child’s doctor before you lower the dose or stop giving this drug. You will need to follow the doctor’s instructions. Tell your child’s doctor if your child has more pain, mood changes, thoughts of suicide, or any other bad effects.

If you do not know how much acetaminophen you can give to your child in a day, ask your child’s doctor or pharmacist. Call your child’s doctor right away if you have given your child too much acetaminophen in a day, even if your child feels well.
• Long-term use of an opioid drug may lead to lower sex hormone levels. Call your child’s doctor if your child has a lowered interest in sex, fertility problems, no menstrual period, or ejaculation problems.
