Opioid Tapering Raises Risk of Overdose and Mental Health Crisis

By Pat Anson, PNN Editor

Taking a patient off opioid medication or reducing their dose – a practice known as opioid tapering – significantly raises the risk of a non-fatal overdose or mental health crisis, according to a large new study.

Researchers at University of California Davis looked at medical and pharmacy claims for over 113,000 patients on long-term opioid therapy at a dose of at least 50 morphine milligram equivalents (MME) per day. About 25% of those patients were tapered.

The study findings, published in JAMA, show that tapered patients were 68% more likely to be treated at a hospital for opioid withdrawal, drug overdose or alcohol intoxication, and they were twice as likely to have a mental health crisis such as depression, anxiety or suicide attempt.

“Our study shows an increased risk of overdose and mental health crisis following dose reduction. It suggests that patients undergoing tapering need significant support to safely reduce or discontinue their opioids.” said first author Alicia Agnoli, MD, an assistant professor at UC Davis School of Medicine. “We hope that this work will inform a more cautious and compassionate approach to decisions around opioid dose tapering.”

Agnoli and her colleagues found that patients on high daily doses who were tapered rapidly were more likely to overdose or have a mental health crisis.

“I fear that most tapering patients aren’t receiving close follow-up and monitoring to make sure they’re coping well on lower doses,” said senior author Joshua Fenton, MD, professor and Vice Chair of Research in the Department of Family and Community Medicine at UC Davis.

The UC Davis study is the largest to date to examine the impact of tapering on patients. Previous studies were generally small, poor quality or limited in scope.

“The paper is well done,” says Stefan Kertesz, MD, an associate professor at the University of Alabama at Birmingham School of Medicine, who is currently leading a study of pain patient suicides. Kertesz said it’s important to remember that people on high opioid doses are usually quite sick. Any abrupt discontinuation of therapy for them is going to be risky.

“People who have been on opioids at a relatively high dose are people who have significant risk. They have significant risk of bad things happening. Whether that’s due to the opioids or not is debatable,” Kertesz told PNN. “This is a group of people who often have high medical morbidity, high disability and high psychological vulnerability. Those risks remain after opioids are stopped or maybe become even worse.”

‘My Life Has Been Ruined’  

The 2016 CDC opioid guideline led to significant increases in tapering, as many doctors, pharmacies, insurers and states adopted its recommendation to limit opioids to no more than 90 MME a day — in many cases even smaller doses.

Three years after the guideline’s release, the Food and Drug Administration warned doctors to be more cautious about tapering after receiving reports of “serious harm in patients who are… suddenly having these medicines discontinued or the dose rapidly decreased.”   

In a recent PNN survey of over 3,600 pain patients, nearly 60% said they were taken off opioids or tapered to a lower dose against their wishes. Nearly every respondent who was tapered said their pain levels and quality of life were worse.

“My life has been ruined by the involuntary opioid medicine taper I have been forced to undergo. I spend so much more time in severe pain, in bed. I no longer can participate in most activities with friends and family. I am so unhappy,” one patient told us.

“I was force tapered to 2/3 of my pain medications. I had been on the same dosage for 8 years without problems. Eight months after being tapered, I developed AFib (atrial fibrillation) and I believe it was due to stress and anxiety of under treated pain,” wrote another patient.

“My pain management doctor tapered my meds by 80% and I had no choice but to accept it.” said another patient. “I have declined so much due to CDC Guidelines that I have become completely homebound and have lost any chance I had for quality of life.”

“I was rapidly tapered without monitoring or concern for my health, pain level, mental health or ability to function,” another patient wrote. “The CDC guideline is completely responsible for increased stigma, patient abandonment, reduced access to care, increase in disability, forcing patients to the black market and to much more affordable but dangerous heroin, and sadly to suicide because the suffering is too great.”

CDC Guideline Revision

The CDC has acknowledged its 2016 guideline caused “unintended harms” and is now in the process of revising its recommendations. But the current draft revision contains the same dose thresholds as the original guideline. That’s drawn criticism from the Opioid Workgroup, an independent panel advising the CDC on the guideline update.

“Many workgroup members voiced concern about the dose thresholds written into the recommendation. Many were concerned that this recommendation would lead to forced tapers or other potentially harmful consequences,” the workgroup said in in a report last month.

In crafting its original guideline, the CDC relied on several researchers and advisors who were critical of opioid prescribing practices. One of them is Roger Chou, MD, a primary care physician who heads the Pacific Northwest Evidence-based Practice Center at Oregon Health & Science University. Chou is not only one of the co-authors of the 2016 guideline, he’s currently involved in efforts to revise it.

As PNN has reported, Chou has numerous ties to Physicians for Responsible Opioid Prescribing (PROP), an anti-opioid activist group that publicly advocates for forced tapering. In 2019, Chou co-authored an op/ed with PROP President Dr. Jane Ballantyne and PROP board member Dr. Anna Lembke that encourages doctors to consider tapering “every patient receiving long term opioid therapy.”

Chou also belonged to a state task force in Oregon that recommended a mandatory opioid tapering policy for Medicaid patients.  

“I can’t tell you whether the tapers I do in my practice are voluntary or involuntary,” Chou told The Bend Bulletin in 2019. “I don’t think there’s anything compassionate about leaving people on drugs that could potentially harm them.”

In a 2017 tweet, PROP founder Andrew Kolodny, MD, challenged the idea that anyone was being harmed by opioid tapering.

“Outside of palliative care, dangerously high doses should be reduced even if patient refuses. Where exactly is this done in a risky way?” wrote Kolodny. “I’m asking you to point to a specific clinic or health system that is forcing tapers in a risky fashion. Where is this happening?”

The UC Davis study appears to have answered Kolodny’s question. It’s happening everywhere.

“This study adds to a growing body of retrospective cohort studies that have identified harms associated with opioid tapering,” lead author Marc Larochelle, MD, wrote in a JAMA editorial that urged tapering policies be reconsidered.

“It is increasingly clear that opioid tapering needs to be approached with caution. In almost all cases, rapid or abrupt discontinuation should be avoided.”
