Opioids are a class of drugs that provide optimal pain relief for people with conditions like cancer or fibromyalgia or for people recovering from surgery. However, opioids can be highly addictive and may lead to opioid dependence, one of the most common substance use disorders in the United States. The risk of dependence isn’t the only potential drawback to opioids, either. This class of medications—which includes codeine, oxycodone, and hydrocodone—also comes with an increased risk of unwanted side effects, including constipation. In fact, constipation affects an estimated 40% to 60% of people taking daily doses of opioids. Constipation also occurs in people taking medications prescribed to treat opioid dependence, such as Suboxone (buprenorphine and naloxone) and methadone. In this article, we discuss why opioid-induced constipation happens, what the leading opioid constipation remedies are, and how to treat and prevent it. We can answer your questions about withdrawal and detox today.Dependence on opioid drugs has been steadily increasing over the past two decades. While this type of medication can provide optimal pain relief for many patients, they do come with a tremendous amount of risks and side effects. One of the most common unwanted side effects are those associated with the gastrointestinal tract, specifically constipation. Several treatment options exist to help manage adverse side effects, but while the individual continues to take daily doses of opioids, constipation remains an issue.
What is Opioid-Induced Constipation (OIC)?
Opioids relieve pain by binding to pain receptors in the nervous system. But opioids can also bind to receptors in the digestive system. This inhibits or slows down involuntary muscle contractions in the stomach and intestines (peristalsis), which generally help the gastric contents move along the gastrointestinal tract. When gastric contents move more slowly than they should, more fluid gets absorbed. This makes a person’s stool hard and can lead to constipation. Opioid drugs can also lead to constipation by increasing anal sphincter tone and disrupting the defecation reflex. Furthermore, opioid drugs can impair digestion by disrupting the healthy colonies of bacteria living in the gut and by decreasing the flow of bile, a critical digestive fluid released by the pancreas. Opioid-induced constipation appears more likely to occur in patients who are older, unemployed, and female, but it can affect anyone taking opioid drugs. Even short-term opioid use may lead to constipation symptoms, which tend to be dose-dependent (i.e., OIC is often worse with higher doses of opioids). The leading symptoms of OIC include:- Constipation, or alternating episodes of constipation or diarrhea
- Straining during defecation
- The sensation of incomplete emptying or evacuation of the rectum
- Bloating
- Abdominal pain
- Nausea
- Vomiting
5 Ways to Relieve Constipation Caused by Opioids
Knowing how to treat opioid constipation is essential for relieving symptoms and preventing complications like anal tears, hemorrhoids, rectal prolapse (where the ends of the intestines protrude through the anus), and bowel obstruction, which can be deadly in severe cases. Here are some leading OIC remedies and prevention strategies to be aware of:1. Use Laxatives and Other Medications to Relieve Constipation
The American Gastroenterological Association (AGA) recommends laxatives as the first line of defense for treating opioid-induced constipation. Laxatives facilitate regular bowel movements by increasing intestinal activity and/or softening the stool. They’re generally considered safe and inexpensive and are often available over the counter (e.g., senna). When traditional laxative therapy isn’t enough to produce acceptable symptom relief, the AGA recommends other prescription laxative medications, including:- Intestinal secretagogues
- Selective 5-HT agonists
- Peripherally-acting μ-opioid receptor antagonist (PAMORA) drugs like
