Specific Warnings and Precautions With Nucynta

Precautions and warnings to be aware of prior to taking Nucynta include the following:
  • Nucynta is a narcotic medication with significant potential for abuse. It is not a good choice for people who have a history of alcohol or drug abuse. Do not take the drug more frequently, longer, or at a higher dose than prescribed. If you feel you may be developing a problem with Nucynta, please seek help from your healthcare provider.
  • Like any other narcotic, Nucynta can cause dizziness and drowsiness, and may increase the risk of falls, particularly in elderly people.
  • Do not drive or operate heavy machinery until you know how Nucynta affects you. Your reflexes and reaction times may be significantly affected, even if you feel fine.
  • This medication can cause slow and irregular breathing, especially at high doses. In severe situations, this may be life-threatening and may be especially dangerous in people with lung problems.
  • This medication can cause problems in people with head injuries or high intracranial pressure. Nucynta should only be used with extreme caution in such circumstances.
  • Nucynta can interfere with the diagnosis of many conditions that cause severe abdominal (stomach) pain.
  • In general, this drug is not recommended for people with seizure disorders.
  • Nucynta can cause a dangerous group of symptoms known as serotonin syndrome. This problem is most common when Nucynta is combined with antidepressants or other medications that affect serotonin (see Nucynta Drug Interactions). Seek immediate medical attention if you develop signs of serotonin syndrome, such as:
    • Confusion or other mental changes
    • A rapid heart rate
    • Nausea
    • Vomiting
    • Diarrhea
    • Hallucinations
    • Blood pressure changes
    • Overactive reflexes
    • Fever
    • Shivering
    • Shakiness
    • Agitation
    • Sweating
    • Seizures
    • Coma.
  • Nucynta can potentially interact with several other medications (see Nucynta Drug Interactions).
  • Nucynta is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known (see Nucynta and Pregnancy).
  • It is unknown if Nucynta passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Nucynta and Breastfeeding).
