Tell your care team if your pain does not go away, if it gets worse, or if you have new or a different type of pain. You may develop tolerance to this medication.

Children may be at higher risk for side effects. Stop giving this medication and call emergency services right away if your child has slow or noisy breathing, has confusion, is unusually sleepy, or not able to wake up.
