Some degree of pain is inevitable in older individuals, and as people pass 80 years of age, the harms of medications used to control chronic pain increase. Pain-reducing medication use in this age group may cause inflammation, gastric bleeding, kidney damage, or constipation.
These risks may lead some clinicians to avoid aggressive pain treatment in their eldest patients, resulting in unnecessary suffering.
“Pain causes harm beyond just the physical suffering associated with it,” said Diane Meier, MD, a geriatrician and palliative care specialist at Mount Sinai Medicine in New York City who treats many people in their 80s and 90s.
Downstream effects of untreated pain could include a loss of mobility and isolation, Dr Meier said. And, as these harms are mounting, some clinicians may avoid using an analgesic that could bring great relief: Buprenorphine.
“People think about buprenorphine like they think about methadone,” Dr Meier said, as something prescribed to treat substance use disorder. In reality, it is an effective analgesic in other situations.
Buprenorphine is better at treating chronic pain than other opioids that carry a higher addiction risk and often cause constipation in elderly patients. Buprenorphine is easier on the kidneys and has a lower addiction risk than opioids like oxycodone.
The transdermal patch form of buprenorphine (Butrans, Purdue Pharma) is changed weekly and starts at low doses.
“There’s an adage in geriatrics: Start low and go slow,” said Jessica Merlin, MD, PhD, a palliative care and addiction medicine physician at the University of Pittsburgh Medical Center in Pittsburgh, Pennsylvania.
Dr Merlin recommends beginning elderly patients with chronic pain on a 10-microgram/hour dose of Butrans, among the lowest doses available. Physicians could monitor side effects, which will generally be mild, with the aim of never increasing the dose if pain is managed.
Nonpharmacologic Remedies, Drug Considerations
“Nonpharmacologic therapy is very underutilized,” Dr Merlin said, even though multiple alternatives to medications can improve chronic pain symptoms at any age.
Cognitive-behavioral therapy or acceptance and commitment therapy can both help people reduce the impact of pain, Dr Merlin said. And for people who can do so, physical therapy programs, yoga, or tai chi are all ways to strengthen the body’s defenses against pain, Dr Merlin added.
Sometimes medication is necessary, however.
“You can’t get an older person to participate in rehab if they are in severe pain,” Dr Meier said, adding that judicious use of medications should go hand in hand with nonpharmacologic treatment.
When medications are unavoidable, internist Douglas S. Paauw, MD, starts with topical injections at the site of the pain — a troublesome joint, for example — rather than systemic medications that affect multiple organs and the brain.
“We try not to flood their body with meds” for localized problems, Dr Paauw said, whose goal when treating elderly patients with pain is to improve their daily functioning and quality of life.
Dr Paauw works at the University of Washington in Seattle and treats people who are approaching 100 years old. As some of his patients have grown older, Dr Paauw’s interest in effective pain management has grown; he thinks that all internists and family medicine physician need to know how to manage chronic pain in their eldest patients.
“Were you able to play with your grandkid? Were you able to go grocery shopping? Were you able to take a walk outside?” These are the kinds of improvements Dr Paauw hopes to see in older patients, recognizing that the wear and tear of life — orthopedic stresses or healed fractures that cause lingering pain — make it impossible for many older people to be pain free.
Pain is often spread throughout the body rather than focusing at one point, which requires systemic medications if physical therapy and similar approaches have not reduced pain. Per American Geriatrics Society (AGS) guidelines, in this situation Dr Paauw starts with acetaminophen (Tylenol) as the lowest-risk systemic pain treatment.
Dr Pauuw often counsels older patients to begin with 2 grams/day of acetaminophen and then progress to 3 grams if the lower dose has manageable side effects, rather than the standard dose of 4 grams that he feels is geared toward younger patients.
When acetaminophen doesn’t reduce pain sufficiently, or aggravates inflammation, Dr Paauw may use the nerve pain medication pregabalin, or the antidepressant duloxetine — especially if the pain appears to be neuropathic.
Tricyclic antidepressants used to be recommended for neuropathic pain in older adults but are now on the AGS’s Beers Criteria of drugs to avoid in elderly patients due to risk of causing dizziness or cardiac stress. Dr Paauw might still use a tricyclic, but only after a careful risk-benefit analysis.
Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Motrin) or naproxen (Aleve) could work in short bursts, Dr Paauw said, although they may cause stomach bleeding or kidney damage in older patients.
This is why NSAIDs are not recommended by the AGS for chronic pain management. And opioids like oxycodone don’t work long at low doses, often leading to dose escalation and addiction.
“The American Geriatrics Society really puts opioids down at the bottom of the list,” Dr Paauw said, to be used “judiciously and rarely.”
Opioids may interact with other drugs to increase risk of a fall, Dr Meier added, making them inadvisable for older patients who live alone.
“That’s why knowing something about buprenorphine is so important,” Dr Meier said.
Dr Meier and Dr Paauw are on the editorial board for Internal Medicine News. Dr Merlin is a trainer for the Center to Advance Palliative Care, which Dr Meier founded.
