When should I call my doctor if I am taking Nucynta?

If you're taking the pain medication Nucynta (tapentadol), call your doctor or get medical emergency help if you experience any of the following serious side effects:
  • slow, shallow or difficult breathing
  • slow or fast heartbeat
  • severe sleepiness
  • cold, clammy skin
  • feeling faint, dizzy, confused or agitated
  • trouble thinking, walking or talking normally
  • seizures
  • hallucinations
  • feeling overheated
  • loss of coordination, twitchiness
Let your doctor know if any of these more common side effects become severe or troubling or won't go away: sleepiness, itching and constipation, nausea or vomiting.

Also call your doctor if Nucynta stops working for you and you aren't getting adequate pain relief. Do not take more Nucynta without talking to your doctor first.

Finally, let your doctor know before you start or stop another medication while taking Nucynta.
