What is Nucynta ER?
Nucynta ER is an opioid pain medication, sometimes called a narcotic.
Nucynta ER is used to treat moderate to severe pain.
The extended-release form of Nucynta ER (Nucynta ER) is for around-the-clock treatment of pain that is not controlled by other medicines. This form of tapentadol is not for use on an as-needed basis for pain.
Nucynta ER may also be used for purposes not listed in this medication guide.
Nucynta ER can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use this medication if you are allergic to Nucynta ER, or if you have:
severe asthma or breathing problems; or
a blockage in your digestive tract (stomach or intestines).
Do not use Nucynta ER if you have taken an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, and tranylcypromine.

any type of breathing problem or lung disease;
drug or alcohol addiction, or mental illness;
liver or kidney disease; or
problems with your gallbladder, pancreas, or thyroid.
If you use Nucynta ER 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 habit-forming medicine may need medical treatment for several weeks. Tell your doctor if you are pregnant or plan to become pregnant.

How should I take Nucynta ER?
Follow all directions on your prescription label. Nucynta ER can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never use this medicine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Nucynta ER may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
