A large-scale study found that some medications used to treat irritable bowel syndrome (IBS) may be linked to a small but measurable increase in the risk of death. The study analyzed nearly 20 years of electronic health records from over 650,000 adults diagnosed with IBS.

IBS is a chronic digestive disorder that affects around 10% of people in the United States. While there is no cure, symptoms can often be managed through dietary changes, behavioral therapies, and medications. Many patients are diagnosed with IBS at a young age and may remain on medications for years. However, most clinical trials of these medications last less than a year, so we know very little about their long-term safety.

The research team examined patients using a range of treatments, including antidepressants, antispasmodics, and opioid-based antidiarrheal medications such as loperamide and diphenoxylate. Their analysis found that long-term use of antidepressants was associated with a 35% increase in the risk of death. Use of loperamide and diphenoxylate was linked to about twice the risk of death compared to those not taking these medications.

The study does not prove that these medications directly cause death. Instead, the associations may reflect a higher likelihood of serious health complications among those taking them, including cardiovascular events, falls, and stroke. Although antidepressants are not FDA-approved specifically for IBS, they are often prescribed to help manage pain and reduce symptom severity.

The researchers stressed that while the increased risks are statistically meaningful, the overall risk for any one patient remains low. Patients should speak with their healthcare provider about the safest and most effective options for managing their symptoms.

Why It Matters

This study highlights the importance of understanding the long-term safety of medications used to treat IBS. As many patients may remain on these medications for years, it's crucial to weigh the small but meaningful risks against the benefits of treatment.

Key Facts

• The study analyzed nearly 20 years of electronic health records from over 650,000 adults diagnosed with IBS.
• Long-term use of antidepressants was associated with a 35% increase in the risk of death.
• Use of loperamide and diphenoxylate was linked to about twice the risk of death compared to those not taking these medications.
• The study does not prove that these medications directly cause death, but rather reflects a higher likelihood of serious health complications.
• The overall risk for any one patient remains low, but patients should speak with their healthcare provider about the safest and most effective options for managing their symptoms.
