Symptoms of OIC

Opioid-Induced Constipation (OIC) is a Different Type of Constipation

Opioid treatment can help relieve moderate to severe pain. Unfortunately, opioid use often comes with the undesired effect of constipation. If you're taking opioid pain medication and experiencing difficulty with bowel movements, speak with your doctor, you may have OIC.

The truth is, OIC is a unique type of constipation that may require a specific kind of treatment.

How Relistor works

RELISTOR works differently from over-the-counter (OTC) laxatives. It’s an FDA-approved prescription medication for opioid-induced constipation specifically designed to target the constipating effect opioids have in the gut, without impacting opioid pain relief in the central nervous system. Tell your doctor if you experience any changes in your pain relief.

Opioids relieve pain by attaching to mu-opioid receptors in the central nervous system.

Opioids may attach to receptors in your gut, which can cause constipation

Relistor is designed to target the constipating effect opioids can have on the gut.

This can help:

  • Move fluid and waste through the bowels
  • Restore fluid movement into the bowels
  • Keep fluid in the bowels
  • Result in a more regular gut
