Opioid as codeine, has similarly demonstrated little benefit in several recent studies.) Low dose morphine may help chronic cough but its use is limited by side effects. In cases of diarrhea-predominate irritable bowel syndrome, opioids may be used to suppress diarrhea. Loperamide is a peripherally selective opioid available without a prescription used to suppress diarrhea. The ability to suppress diarrhea also produces constipation when opioids are used beyond several weeks. Naloxegol, a peripherally-selective opioid antagonist is now available to treat opioid induced constipation. Opioids may help with shortness of breath particularly in advanced diseases such as cancer and COPD among others.
