Chronic Pain Management in the Elderly

Initial Pharmacologic Approach

The American Geriatrics Society recommends starting with acetaminophen as first-line therapy for mild-to-moderate pain in elderly patients, then adding topical NSAIDs or duloxetine for inadequate relief, while implementing a multimodal approach that combines physical therapy and cognitive-behavioral interventions, reserving opioids only for severe refractory pain at 25% of standard adult doses 1
The American Geriatrics Society suggests beginning with scheduled acetaminophen as the foundation of pain management for mild-to-moderate pain in elderly patients, using regular dosing rather than PRN to maintain steady analgesic levels 2
Monitoring total daily dose is crucial to avoid hepatotoxicity, particularly in patients with hepatic impairment or alcohol use, as recommended by the American Geriatrics Society 3
The American Geriatrics Society recommends adding topical NSAIDs, such as diclofenac gel, or lidocaine patches 5% for focal or regional pain before considering systemic medications, as these formulations act locally with minimal systemic absorption, reducing the risk of renal, cardiovascular, and gastrointestinal toxicity 1, 4

The American Geriatrics Society suggests initiating all centrally-acting medications at 25% of standard adult doses in patients over 75 years, reducing doses by approximately 20-25% per decade after age 55, and using small dose increments with intervals of 1-2 weeks between adjustments to monitor for both efficacy and adverse effects 3, 8

The American Geriatrics Society recommends reserving opioids only for severe pain refractory to multimodal non-opioid approaches, or for breakthrough pain at the lowest effective dose for the shortest duration, and starting with 25% of standard adult dose and titrating slowly 2, 4, 8
The American Geriatrics Society suggests avoiding fixed-dose combinations with acetaminophen to prevent exceeding safe acetaminophen limits, and always prescribing prophylactic bowel regimen with any opioid therapy 8

The American Geriatrics Society recommends implementing physical therapy focused on strengthening, flexibility, and functional restoration as a core component of pain management, and considering occupational therapy for adaptive strategies and assistive devices 2, 4
Cognitive-behavioral therapy is recommended as a first-line approach for the pain-cognition connection, addressing maladaptive thoughts and promoting adaptive coping behaviors, as suggested by the American Geriatrics Society 4

The American Geriatrics Society recommends assessing pain intensity using a numeric rating scale or verbal descriptor scale at every visit, and monitoring the "Four A's" at each visit: Analgesia, Activities of daily living, Adverse effects, and Aberrant drug-taking behaviors 2, 7
Establishing realistic, mutually-agreed comfort goals focused on functional improvement and quality of life, rather than complete pain elimination, is recommended by the American Geriatrics Society 3

The American Geriatrics Society suggests reviewing all medications for drug-drug interactions, particularly with CYP450 inhibitors/inducers affecting analgesic metabolism, and avoiding anticholinergic medications that increase delirium and falls risk 1, 3
Under-treatment is common, and elderly patients often minimize pain complaints due to stoicism or fear of being burdensome, as noted by the American Geriatrics Society 2

The American Geriatrics Society recommends referring to a pain specialist or physiatrist if there is no improvement after 8-12 weeks of comprehensive conservative management, and considering referral for complex pain syndromes, opioid-refractory cancer pain, or when interventional procedures may be beneficial 1, 7
