According to a small, preliminary study, a drug that’s typically prescribed for fibromyalgia might also relieve pain related to irritable bowel syndrome (IBS)—the common GI disorder estimated to affect as many as 15% of adults. There’s not enough evidence to recommend pregabalin (sold under the brand name Lyrica) to IBS patients yet, says the lead investigator, but she hopes her research will prompt further studies on the topic. There is considerable overlap when it comes to fibromyalgia and IBS, says Yuri Saito-Loftus, MD, a gastroenterologist at the Mayo Clinic.
