Nucynta (tapentadol) is an opioid pain medication. An opioid is sometimes called a narcotic.
Nucynta is a prescription medicine that is used to treat moderate to severe pain.
Nucynta ER (extended-release) is for around-the-clock treatment of pain that is not controlled by other medicines. Nucynta ER is not for use on an as-needed basis for pain.
Do not use Nucynta if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, tranylcypromine, and others.
You should not use Nucynta if you have severe breathing problems, or a bowel obstruction called paralytic ileus.
Nucynta can slow or stop your breathing, especially when you start using this medicine or whenever your dose is changed. Never take Nucynta in larger amounts, or for longer than prescribed. Do not crush, break, or open an extended-release tablet. Swallow it whole to avoid exposure to a potentially fatal dose.
Tapentadol may be habit-forming, even at regular doses. Take Nucynta exactly as prescribed by your doctor. Never share the medicine with another person. MISUSE OF NARCOTIC PAIN MEDICATION CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Keep the medication in a place where others cannot get to it.
Tell your doctor if you are pregnant. Tapentadol may cause life-threatening withdrawal symptoms in a newborn if the mother has taken this medicine during pregnancy.
Fatal side effects can occur if you use Nucynta with alcohol, or with other drugs that cause drowsiness or slow your breathing.
Before taking this medicine
You should not use it if you are allergic to tapentadol, or if you have:
- severe asthma or breathing problems;
- a stomach or bowel obstruction (including paralytic ileus); or
- if you have taken an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, or tranylcypromine.
To make sure it is safe for you, tell your doctor if you have ever had:
- breathing problems, sleep apnea (breathing that stops during sleep);
- a head injury, brain tumor, or seizures;
- alcoholism or drug addiction, mental illness;
- urination problems,
- liver or kidney disease; or
- problems with your gallbladder, pancreas, thyroid, or adrenal gland.
If you use opioid medicine while you are pregnant, your baby could become dependent on tapentadol. 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.
Ask a doctor before using Nucynta if you are breastfeeding. Tell your doctor if you notice severe drowsiness or slow breathing in the nursing baby.
