About Opioid-Induced Constipation (OIC) OIC is a condition caused by prescription opioid pain medicines. Opioids play an important role in chronic pain relief and work by binding to mu-receptors in the central nervous system, but they can also bind to mu-receptors in the bowel, which can result in patients suffering from OIC. OIC is the most prevalent and disabling adverse effect associated with opioid therapy, estimated to affect between 40-80% of the millions of patients taking chronic opioid therapy each year⁴.
