It's called opioid-induced constipation (OIC)

Up to half of patients who are taking opioids for their chronic non-cancer pain report having OIC.

OIC is different from regular constipation and may last for as long as you take opioids. Continue to have open and honest conversations with your healthcare provider about your symptoms of OIC.

What happens when you take opioids?

Brain icon

Opioids reduce pain signals to your brain, which can help your chronic non-cancer pain ...

Digestive tract icon

... but those same receptors can be found in your gut or digestive tract, too, which may cause constipation.

OIC can last as long as you take an opioid.*

    Any of the following can be symptoms of OIC:

  • Going less often
  • Pushing harder (straining more)
  • Not going all the way
  • Passing harder stools

*Discontinue SYMPROIC® if treatment with opioid pain medication is discontinued.

Don’t wait to talk to your doctor about your symptoms

OIC can leave you feeling uncomfortable and frustrated, especially when discussing the condition with your doctor. As awkward as these conversations may seem, they are extremely important. Your doctor can only help you feel better if they understand what you are going through. Use this Doctor Discussion Guide to help you begin an open and honest conversation with your doctor.
