  • A strong prescription pain medicine that contains an opioid (narcotic) that is used to manage pain severe enough to require daily around-the-clock, long-term treatment with an opioid, when other pain treatments such as non-opioid pain medicines or immediate-release opioid medicines do not treat your pain well enough or you cannot tolerate them.
  • Also used to manage pain from damaged nerves (neuropathic pain) that happens with diabetes and is severe enough to require daily around-the-clock, long-term treatment with an opioid, when other pain treatments such as non-opioid pain medicines do not treat your pain well enough or you cannot tolerate them.
  • A long-acting (extended-release) opioid pain medicine that can put you at risk for overdose and death. Even if you take your dose correctly as prescribed you are at risk for opioid addiction, abuse, and misuse that can lead to death.

Important information about NUCYNTA ER:
  • Get emergency help or call 911 right away if you take too much NUCYNTA ER (overdose). When you first start taking NUCYNTA ER, when your dose is changed, or if you take too much (overdose), serious or life threatening breathing problems that can lead to death may occur. Talk to your healthcare provider about naloxone, a medicine for the emergency treatment of an opioid overdose.
  • Taking NUCYNTA ER with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.
  • Never give anyone else your NUCYNTA ER. They could die from taking it. Selling or giving away NUCYNTA ER is against the law.
  • Store NUCYNTA ER securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.
Do not take NUCYNTA ER if you have:
  • severe asthma, trouble breathing, or other lung problems.

  • Call your healthcare provider if the dose you are taking does not control your pain.
  • Do not stop taking NUCYNTA ER without talking to your healthcare provider.
