Opioids in Older Adults: Falls, Delirium, and Dose Adjustments

Why Opioids Are Riskier for Older Adults

Older adults don’t process opioids the same way younger people do. Their kidneys and liver don’t clear drugs as quickly. Their body fat increases while muscle mass declines. Their blood-brain barrier becomes more permeable. These changes mean even small doses can cause big problems-sedation, confusion, dizziness, and a much higher chance of falling.

Between 2005 and 2014, emergency room visits for opioid-related issues in people 65 and older jumped by over 110%. That’s not just a trend-it’s a crisis. And it’s not just about addiction. Many older adults are prescribed opioids for chronic pain, but they don’t realize how dangerous these drugs can be for their age group.

Falls: A Silent but Deadly Consequence

Falls are the leading cause of injury and death in older adults. Opioids make them far more likely. How? They slow down reaction time, blur vision, lower blood pressure when standing up, and cause dizziness. Even weak opioids like tramadol can trigger hyponatremia-a drop in sodium levels-that leads to confusion and unsteadiness.

One study of 2,341 adults over 60 found that those taking opioids had a 6% fracture rate over 33 months, compared to 4% in those not taking them. The difference wasn’t quite statistically significant, but the pattern was clear: opioids = more falls = more broken hips and skulls.

And it’s not just the drug itself. When opioids are mixed with other medications-like benzodiazepines, antidepressants, or even over-the-counter sleep aids-the risk multiplies. Drug interactions affect enzymes like CYP2D6 and CYP3A4, which are already slower in older adults. The result? More sedation, longer-lasting effects, and a higher chance of ending up in the hospital after a fall.

Delirium: When Pain Meds Cause Confusion

Delirium isn’t just "being forgetful." It’s a sudden, dangerous shift in mental state-confusion, hallucinations, agitation, or extreme drowsiness. In older adults, especially those with dementia, opioids are a major trigger.

A 2023 study of 75,471 Danes over 65 with dementia found that those who started opioids had an elevenfold higher risk of dying in the first two weeks. That’s not a typo. Eleven times. The researchers didn’t find this was due to overdose alone. It was the brain’s reaction to the drug-disrupting alertness, sleep cycles, and cognition.

Doctors often mistake delirium for worsening dementia. Families think Grandma is just "getting worse." But if she started an opioid last week and now doesn’t recognize her own children, it might not be dementia-it might be the medicine.

Dose Adjustments: Start Low, Go Slow

There’s no such thing as a "normal" opioid dose for older adults. What’s safe for a 40-year-old can be deadly for a 75-year-old. Experts agree: start at 25 to 50% of the usual adult dose. Then wait. Watch. Reassess.

For example, if a younger patient gets 10 mg of oxycodone every 6 hours, an older adult might start with 2.5 mg every 8 hours. And even that might be too much. Some patients need only 1 mg every 12 hours to get relief.

It’s not about being stingy. It’s about precision. Older adults need less, but they also need careful monitoring. Are they sleeping too much? Are they stumbling in the hallway? Do they seem foggy after taking their pill? If yes, the dose is too high.

Don’t wait for a fall to happen. Check in weekly. Use simple tools like the STOPPFall checklist-designed by geriatric specialists-to help decide if the opioid is doing more harm than good.

Deprescribing: When It’s Time to Stop

Many older adults have been on opioids for years. They think they need them. But long-term use doesn’t always mean better pain control. Often, it just means more side effects.

Deprescribing isn’t about quitting cold turkey. It’s about reducing slowly, with support. Tapering too fast can cause withdrawal-sweating, nausea, anxiety, insomnia. But tapering too slow keeps the risks alive.

Start by cutting the dose by 10-20% every 1-2 weeks. Watch for pain flare-ups and withdrawal signs. Replace opioids with non-drug options: physical therapy, heat packs, acupuncture, or even cognitive behavioral therapy for pain.

And here’s the hard truth: many older adults resist stopping opioids because they fear pain will return. But what they don’t realize is that the opioids themselves may be making their pain worse over time-through a condition called opioid-induced hyperalgesia, where the nervous system becomes more sensitive to pain.

What Doctors and Families Should Do

Primary care doctors often feel unprepared. Nearly half say they lack confidence in tapering opioids safely. And older patients? They rarely bring up side effects. They’re afraid of being seen as complainers. Or they don’t know what’s normal.

Here’s what works:

1. Ask directly: "Have you felt dizzy or confused since starting this medicine?"
2. Review every pill in the medicine cabinet-not just opioids, but everything.
3. Use the START/STOPP criteria: a proven checklist for safe prescribing in older adults.
4. Involve pharmacists. They spot dangerous interactions doctors miss.
5. Build trust. If the patient doesn’t feel heard, they won’t agree to change.

And families: don’t assume your parent is just aging. If they’re suddenly falling, forgetting names, or sleeping all day, ask: "Could this be the pain meds?"

Non-Opioid Alternatives That Actually Work

Opioids aren’t the only option. And often, they’re not the best one.

• Physical therapy: Strength and balance training reduce pain and prevent falls.
• Topical NSAIDs: Creams or gels with diclofenac or ibuprofen work for joint pain with almost no systemic side effects.
• Cognitive behavioral therapy: Helps reframe how the brain perceives pain.
• Acupuncture and massage: Proven to help chronic back and knee pain in older adults.
• TENS units: Small devices that send gentle electrical pulses to block pain signals.

These options don’t come with a risk of delirium or a broken hip. They take more time and effort-but they’re safer, and often just as effective.

The Bottom Line

Opioids aren’t evil. They have a place in pain management. But for older adults, the risks often outweigh the benefits. Falls, delirium, heart attacks, and early death aren’t side effects-they’re predictable outcomes when doses aren’t adjusted for age.

The solution isn’t to stop all opioids. It’s to start smarter. Prescribe less. Monitor closer. Replace when possible. And always ask: "Is this helping, or just hiding the problem?"

If you or someone you love is over 65 and on opioids, talk to a doctor. Ask about alternatives. Ask about dose reduction. Ask about fall risk. Don’t wait for a fall to happen before you act.

What Comes Next?

If you’re managing opioids for an older adult, the next step is simple: schedule a medication review. Bring every pill bottle-prescription, over-the-counter, supplements-to your doctor or pharmacist. Ask: "Is this still necessary?" "Could it be causing dizziness or confusion?" "Are there safer alternatives?"

Change doesn’t have to be dramatic. Sometimes, cutting one pill in half, switching to a topical cream, or adding a daily balance exercise makes all the difference. The goal isn’t to live without pain. It’s to live without fear-of falling, of forgetting, of dying too soon because a pill didn’t fit the person taking it.
