Opioid-Induced Constipation (OIC) is a Unique 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 medicine and experiencing difficulty with bowel movements, you may have OIC.

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.
See how
 
 
Opioids relieve pain by attaching to mu-opioid receptors in the central nervous system.
Opioids attach to mu-opioid receptors in your bowels. This can cause constipation.
Relistor can help keep opioids from attaching to mu-opioid receptors in the gut, decreasing the constipating effects.
