Beers Criteria: 15 Medications Adults Over 65 Should Avoid in 2026

Your doctor prescribed it. The pharmacy filled it. It's been in your medicine cabinet for years. But there's a good chance one or more medications you're currently taking is on the official "danger list" for adults over 65 — and your doctor may not have told you. The American Geriatrics Society Beers Criteria® is a research-based list of nearly 100 drugs that carry disproportionate risks for older adults. Forty to fifty percent of adults over 65 take at least one medication on this list. Here's everything you need to know — including which specific drugs are on the list, why they're dangerous at your age, and what safer alternatives exist.

What Is the Beers Criteria — and Why Should You Care?

The Beers Criteria (officially the AGS Beers Criteria® for Potentially Inappropriate Medication Use in Older Adults) was created by Dr. Mark Beers in 1991 and is now updated every 3–4 years by a panel of geriatrics experts at the American Geriatrics Society. The most recent update was published in 2023.

It's not a fringe document — it's the gold standard reference tool used by geriatricians, pharmacists, and hospital medication safety teams across the United States. Medicare even uses Beers Criteria medications as a quality measure: prescribing them to elderly patients is tracked as a potential quality failure.

So why are so many seniors still taking these drugs? Several reasons: primary care physicians may not specialize in geriatrics and may not be up-to-date on the 2023 revisions; patients are often seen by multiple specialists who don't coordinate medications; drugs that were appropriate at age 50 are not always re-evaluated at 65 or 70; and many Beers Criteria drugs are available over-the-counter, meaning patients buy them without any physician involvement at all.

Why Medications Work Differently After 65

Understanding why these drugs are more dangerous requires understanding how aging changes the body's relationship with medications. This is not about being "weaker" — it's about physiological changes that affect how every drug is absorbed, distributed, processed, and eliminated:

• Kidney function declines: Glomerular filtration rate (GFR) — the measure of how well kidneys filter drugs — declines approximately 1% per year after age 40. By age 70, kidney function may be 30% lower than at age 30, even without any kidney disease. Drugs cleared by the kidneys stay in the bloodstream longer and reach higher concentrations.
• Liver metabolism slows: The liver's cytochrome P450 enzyme system — responsible for breaking down most medications — becomes less efficient with age. This prolongs drug half-life and increases risk of accumulation and toxicity.
• Body composition changes: Fat mass increases, lean mass decreases, and total body water decreases with age. Fat-soluble drugs (like many benzodiazepines) have a larger volume of distribution, extending their duration of action significantly.
• Blood-brain barrier permeability increases: The blood-brain barrier becomes less effective at excluding large molecules, making the brain more vulnerable to drugs with central nervous system effects — including anticholinergic drugs, sedatives, and opioids.
• Sensitivity to drug effects increases: The aging brain has fewer dopamine and acetylcholine receptors, making it more sensitive to drugs that affect these systems. Lower doses produce stronger effects — and more side effects.
• Polypharmacy amplifies all risks: The average 65+ adult takes 4–5 prescription medications. Each additional drug multiplies the risk of interactions, side effects, and medication errors.

The Complete 15-Drug Comparison Table: Beers Criteria High-Priority Medications

The following table covers the 15 most commonly prescribed or used Beers Criteria medications for adults over 65. Each is rated by risk level, with senior-specific explanations and safer alternatives. This is the reference your pharmacist has — presented in plain language for the first time.

Age-Specific Risk Breakdown: How Danger Scales With Each Decade

The Beers Criteria applies to all adults over 65, but the risks are not uniform across all ages. Here's how the risk landscape changes decade by decade — the aspect of medication safety that almost no mainstream article addresses:

The Drugs That Most Commonly Fly Under the Radar

Some Beers Criteria medications are obvious — nobody is surprised that Demerol (meperidine) or long-term antipsychotics are dangerous. But several medications on the list catch seniors completely off guard because they seem routine, are sold over-the-counter, or have been taken for years without obvious problems. Here are the four most under-recognized risks:

1. Diphenhydramine — The Most Dangerous OTC Medication for Seniors

Diphenhydramine is everywhere in the senior population. It's in Benadryl (the world's most recognizable antihistamine), every "PM" pain reliever (Tylenol PM, Advil PM), ZzzQuil, and Unisom SleepTabs. It's inexpensive, works fast, and most seniors have taken it for decades without obvious incident. This is what makes it so insidious.

Diphenhydramine crosses the blood-brain barrier more efficiently in seniors than in younger adults. It blocks acetylcholine receptors in the brain — the very neurotransmitter system that Alzheimer's disease destroys. Multiple large studies have now found that cumulative diphenhydramine use is associated with increased dementia risk. A landmark 2015 JAMA Internal Medicine study found that taking diphenhydramine for 3 years or more was associated with a 54% increased risk of dementia. Even short-term use causes measurable cognitive impairment — the "drugged" feeling that comes with Benadryl is more pronounced and longer-lasting in seniors, and is identical to the early symptoms of delirium.

The safer alternative for allergies: second-generation antihistamines like cetirizine (Zyrtec), loratadine (Claritin), or fexofenadine (Allegra) are equally effective for allergy symptoms with minimal blood-brain barrier penetration and essentially zero anticholinergic burden. For sleep: melatonin 0.5–1mg (not 10mg — the higher doses many products use are unnecessary) or cognitive behavioral therapy for insomnia (CBT-I), which is more effective than any sleep medication long-term.

2. Benzodiazepines — The "Just for Anxiety" Drug That Breaks Hips

Benzodiazepine prescriptions in older adults are one of the most persistent problems in geriatric medicine. Despite clear evidence of harm, millions of seniors take Xanax, Ativan, Klonopin, or Valium daily — often prescribed years ago for anxiety or sleep, continued without re-evaluation. The numbers are striking: benzodiazepine users over 65 have a 3x higher risk of hip fracture than non-users. Hip fractures are one of the leading causes of mortality in seniors — approximately 20–30% of older adults who sustain a hip fracture die within one year.

The danger comes from three mechanisms: sedation impairs reaction time and balance; muscle relaxation reduces the body's reflexive ability to prevent falls; and prolonged half-life in seniors means significant drug levels are still present when the patient gets up at night to use the bathroom — the most common time of senior falls. As we've noted in our comprehensive guide to falls prevention for seniors, medication review is among the most impactful interventions available.

If you're currently taking a benzodiazepine and want to stop, do not stop abruptly — benzodiazepine withdrawal can be life-threatening. Talk to your physician about a supervised taper protocol. The BRAVE trial and multiple other studies show that gradual tapering, combined with CBT, successfully eliminates benzodiazepine dependence in the majority of older adults who attempt it.

3. Oral NSAIDs — The Pain Relief That Can Cost You Your Kidneys

Ibuprofen and naproxen are so familiar that most seniors don't consider them "real" medications with serious risks. But for adults over 65, regular use of oral NSAIDs is associated with dramatic increases in acute kidney injury, gastrointestinal bleeding, and cardiovascular events. The kidney risk is particularly underappreciated: NSAIDs work by blocking prostaglandins that are critical for maintaining kidney blood flow. At any age this is a risk, but when kidney function is already reduced by 30–40% due to normal aging, the risk is amplified significantly.

The gut-wrenching irony is that many seniors take NSAIDs for arthritis pain that could be better managed through other approaches — and the NSAID use accelerates the kidney damage that will eventually limit their treatment options further. For those managing joint pain, we cover the safer alternatives in detail in our article on evidence-ranked hip pain solutions after 60.

4. Alpha-Blockers for Blood Pressure — And the Fall Nobody Saw Coming

Alpha-blockers (doxazosin, terazosin, prazosin) relax blood vessels and are used for both high blood pressure and enlarged prostate (BPH). The Beers Criteria flags them specifically for blood pressure treatment because they cause orthostatic hypotension — the rapid drop in blood pressure that occurs when you stand from a sitting or lying position. This is the same mechanism behind dizziness when standing up after 60 that affects an estimated 20% of adults over 70.

For blood pressure, better options exist that don't carry this fall risk. For BPH specifically, tamsulosin (Flomax) is more selective for prostate tissue and less likely to cause blood pressure effects — and is not on the Beers Criteria. If you're taking doxazosin for blood pressure (not prostate), ask your prescriber about switching to an ACE inhibitor, ARB, or calcium channel blocker.

The Medication Review Conversation: What to Actually Say to Your Doctor

Many seniors feel uncomfortable questioning their physician's prescriptions. The Beers Criteria gives you a non-confrontational, evidence-based opening. Here's a framework that works:

Step 1: Print or bring this article to your appointment. Say: "I read about the AGS Beers Criteria — the geriatric medication safety list. I want to make sure my current medications are appropriate for my age. Can we go through them together?"

Step 2: Ask specifically about each Beers Criteria drug you recognize. For each one: "Is there a safer alternative for someone my age?" — most physicians will welcome this question. It signals you're engaged in your care.

Step 3: Request a medication therapy management (MTM) review. Medicare Part D beneficiaries who meet certain criteria are entitled to a free annual comprehensive medication review by a clinical pharmacist. This specifically identifies inappropriate medications and drug interactions. Call your Part D plan to ask if you qualify.

Step 4: Ask about deprescribing. For medications you've taken for years — especially sleep medications, anxiety medications, or over-the-counter sleep aids — ask: "Is there a reason I still need this? Can we try reducing or stopping it?" Deprescribing studies in older adults consistently show that reducing inappropriate medication burden improves cognitive function, reduces falls, and paradoxically often improves the symptom the drug was supposed to be treating.

The Safer Alternative Approach to Common Senior Health Challenges

For nearly every health issue addressed by a Beers Criteria medication, a safer or equally effective alternative exists for older adults. Here's the rundown by condition:

For Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) is the single most effective treatment for chronic insomnia — more effective than any sleep medication, with no side effects and durable long-term results. Multiple apps (SleepStation, Sleepio) deliver CBT-I digitally. Pharmacologically, low-dose doxepin (3–6mg) has FDA approval specifically for insomnia in the elderly and has a favorable safety profile compared to benzodiazepines or Z-drugs. Melatonin at low doses (0.5mg–1mg, not 5–10mg) can help with sleep onset. For sleep problems related to anxiety, addressing the anxiety with SSRIs or SNRIs is more appropriate than sedative hypnotics.

For Anxiety

SSRIs (escitalopram, sertraline) and SNRIs (duloxetine, venlafaxine) are first-line treatments for generalized anxiety disorder in seniors and are not on the Beers Criteria. Buspirone is a non-addictive anxiolytic that is effective for anxiety without sedation or fall risk. Psychotherapy (particularly CBT) remains highly effective for anxiety in older adults. Short-term benzodiazepine use (days, not weeks or months) may occasionally be appropriate for acute situational anxiety under close physician supervision.

For Allergies

Second-generation antihistamines — cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra) — are all safe for seniors and have essentially no anticholinergic effects. Nasal corticosteroid sprays (Flonase, Nasacort) are superior for nasal allergy symptoms and have minimal systemic absorption. Our guide to strengthening the immune system after 60 covers several dietary and lifestyle approaches that reduce allergy severity naturally.

For Pain Management

Acetaminophen (Tylenol) at appropriate doses is safe for most seniors and effective for mild-to-moderate pain. Topical diclofenac gel (Voltaren OA) provides anti-inflammatory pain relief with minimal systemic absorption — the kidney, GI, and cardiovascular risks of oral NSAIDs are largely absent with the topical form. Duloxetine (Cymbalta) has FDA approval for chronic musculoskeletal pain and is appropriate for seniors. For severe pain requiring opioids, careful dose adjustments are needed — but meperidine (Demerol) should never be used.

For Overactive Bladder

Mirabegron (Myrbetriq) works via a completely different mechanism than anticholinergic bladder medications and avoids all the cognitive and constipation side effects. Pelvic floor physical therapy is highly effective (60–70% improvement in multiple studies) and has zero drug interactions. Behavioral approaches including scheduled voiding, fluid management, and urge suppression techniques are first-line recommendations before any medication in seniors.

A Note on "Do Not Abruptly Stop" Medications

A critical caution: while the Beers Criteria identifies these drugs as inappropriate for seniors, this does NOT mean you should stop taking them without medical supervision. Several medications on the Beers list — particularly benzodiazepines, certain antidepressants, and some blood pressure medications — can cause severe or life-threatening withdrawal if stopped suddenly. Always discuss any medication change with your physician before acting. The goal is supervised deprescribing, not unilateral self-discontinuation.

Also worth noting: the Beers Criteria is not absolute. Occasionally, a Beers Criteria medication is genuinely the best choice for a specific patient in a specific situation. A physician familiar with geriatric prescribing will factor in your individual health profile. The list is a guide to trigger careful conversation — not a ban on these drugs in all circumstances.
