Ulcerative Colitis and NSAIDs: Do You Actually Need to Avoid Them?

Nonsteroidal anti-inflammatory drugs (NSAIDs) can knock out pain fast.

But if you have ulcerative colitis (UC), your provider may recommend avoiding NSAIDs.

Some studies have shown a connection between NSAIDs and flares of inflammatory bowel diseases (IBDs) like UC.

But these studies were small, and more recent results suggest NSAIDs may not cause as much harm as once thought in some people with IBDs.

But many experts still advise against taking this type of pain medication.

Before taking NSAIDs, it’s important to talk to your healthcare provider first about the risks and their recommendations for pain management.

Why Are People With Ulcerative Colitis Told to Avoid NSAIDs?

NSAIDs like ibuprofen (Motrin, Advil), naproxen (Aleve), and aspirin help control pain by blocking inflammation-causing chemicals in the body.

“NSAIDs work by blocking enzymes called COX-1 and COX-2,” says Adam Mayer, MD, a rheumatologist and the codirector of the Hackensack University Medical Center inflammatory bowel disease–related spondyloarthritis clinic in Hackensack, New Jersey.

“While blocking COX-2 reduces inflammation and pain, blocking COX-1 can lead to gastrointestinal issues,” says Dr. Mayer, who typically advises his patients with IBD to avoid NSAIDs.

What Are the Risks of NSAIDs for People With Ulcerative Colitis?

UC causes inflammation in the lining of your large intestine, which leads to ulcers, pain, and frequent diarrhea.

Because NSAIDs can also damage the lining of the GI tract for some people, experts have had concerns they may make UC symptoms worse.

At its most severe, NSAID damage may include:

  • Intestinal ulcers
  • Rectal bleeding
  • Narrowed intestines (strictures)
  • Openings in your bowel wall (perforations)

“People with ulcerative colitis can also have flares after taking NSAIDs, especially if their disease is active, but how sensitive someone is can vary,” says Tauseef Ali, MD, the medical executive director at SSM Health St. Anthony Digestive Care and the director of the Crohn’s and Colitis Center of Excellence in Oklahoma City, Oklahoma.

One study of about 35,000 people with IBD found a connection between taking NSAIDs and having a higher risk for UC flares. But large study reviews have found inconsistent results and more studies are needed to better understand how NSAIDs affect UC.

Do People With Ulcerative Colitis Actually Need to Avoid NSAIDs?

The research on NSAIDs and IBD has not offered a definitive answer yet on the safety of these pain medications for people with UC.

“Recently, a large study involving nearly 300,000 IBD patients found the risk of NSAID use leading to IBD-related hospitalizations was very small,” says Andrew DuPont, MD, a gastroenterologist with UT Health Houston and a professor of gastroenterology, hepatology, and nutrition at McGovern Medical School in Houston. The same study showed a smaller risk in people with UC compared to those with Crohn’s disease, Dr. DuPont says.

But most experts still urge caution when considering NSAIDs for pain when you have UC.

Sometimes, though, the benefits of NSAIDs may outweigh the risks, says Dr. Ali. “For example, someone with severe pain after surgery, a sudden muscle or joint injury, kidney stones, headaches, menstrual cramps, or inflammatory arthritis might need NSAIDs for a short time,” says Ali.

The decision should be tailored to each person, says Ali. Consider the following factors:

  • How active your disease is
  • How you have responded to NSAIDs before
  • What other treatment options are available
  • Why pain control is needed

How to Manage Pain With Ulcerative Colitis

If you have pain and aren’t sure how to treat it, talk to your provider first.

They may recommend acetaminophen (Tylenol) or other options before trying NSAIDs.

NSAID Alternatives

“For more severe pain, there are several prescription medications we can consider that are safer for the gut than NSAIDs,” says Mayer. Some options, he says, include:

  • Antispasmodics for cramping
  • Antidepressants for chronic pain
  • Gabapentin and pregabalin for nerve-related pain

Your provider may prescribe opioid pain medications for severe short-term pain or injury, says Mayer. “[But] they are generally avoided for long-term use due to the risk of dependence and other side effects.”

Lifestyle Changes for Pain Management

“Beyond medication, lifestyle modifications can also play a significant role in pain management,” says Mayer.

He recommends these habits to help decrease chronic pain with UC:
  • Dietary changes: Identify and avoid trigger foods to help manage symptoms.
  • Stress management: Techniques like yoga, meditation, and regular exercise can help reduce stress, a known IBD trigger. This in turn may reduce IBD flares.

Precautions While Taking NSAIDs

“If your inflammatory bowel disease is in deep remission, a short course of NSAIDs may be okay if needed,” says Ali.

For his patients taking NSAIDs, Ali watches for any GI-related side effects, like:

  • More frequent diarrhea
  • Rectal bleeding
  • Stomach pain

Ali also recommends these precautions while taking NSAIDs with UC:

  • Use the lowest dose that works.
  • Keep the treatment as short as possible.
  • Try to avoid taking NSAIDs every day for a long time.
  • Work closely with your gastroenterologist, especially if your UC has been active recently.

“Do not ignore ongoing pain,” says Ali. “If you have pain that does not go away, talk to your gastroenterologist instead of treating yourself with NSAIDs over and over.”
