—————————————————————-
Adults over 65 take an average of several prescription medications daily, and a large share — commonly cited around 40 percent — take five or more, the usual threshold for polypharmacy. Add over-the-counter drugs and supplements and the daily pill count often crosses ten. Medication management for seniors is not a peripheral concern: missed doses, duplications, and drug interactions account for a substantial share of avoidable hospitalizations in older adults, and the risk rises with each additional medication.
This guide covers practical tools, the most useful safety frameworks (the Beers Criteria, STOPP/START, and deprescribing), and the resources caregivers can lean on. For deeper dives on related issues, see our polypharmacy guide and fall prevention guide. Broader senior topics live in our medical conditions library. Nothing here is a substitute for advice from the prescriber and pharmacist who know the full regimen.
Why Medication Management Gets Harder With Age
Several changes converge after 65. Renal (kidney) function tends to decline, slowing clearance of many drugs. Body composition shifts toward fat, altering the distribution of fat-soluble medications. Liver enzyme activity changes. The blood-brain barrier can become more permeable, increasing sensitivity to drugs that act on the central nervous system. Memory and executive-function changes can interfere with adherence. And when multiple specialists each add medications, no single clinician may have visibility into the full regimen.
The American Geriatrics Society’s Beers Criteria — most recently updated in 2023 — list medications considered potentially inappropriate for adults 65 and older. Common entries include first-generation antihistamines (such as diphenhydramine), benzodiazepines, anticholinergic drugs for overactive bladder, NSAIDs in patients with kidney disease or heart failure, and proton pump inhibitors used long-term without a clear indication. The 2023 update also refined guidance on anticoagulants and on estrogen use, and the AGS has since published a companion Beers Criteria Alternatives List to help clinicians choose safer substitutes. The Beers Criteria are a prompt for a conversation with a clinician, not a checklist for stopping medications yourself.
The Anatomy of an Annual Medication Review
An annual brown-bag review is one of the highest-yield interventions in geriatric care. The patient brings every bottle in the house — prescriptions, over-the-counter products, supplements, eye drops, inhalers, and topicals — to a primary care or pharmacist visit. Each item is reviewed for current need, duplications (for example, two proton pump inhibitors from different specialists), interactions, dose appropriateness for kidney function, and Beers Criteria flags.
The Medicare Annual Wellness Visit explicitly includes a medication review. Many Medicare Advantage and Part D plans also cover a Comprehensive Medication Review by a pharmacist for patients who meet medication therapy management (MTM) criteria — typically those with multiple chronic conditions and several medications. Asking for one is straightforward, and it is usually free to the patient when they qualify.
Tools That Actually Help
Weekly pill organizers (multi-compartment boxes with morning, noon, evening, and bedtime slots) work well for cognitively intact seniors with stable regimens. Filling them on the same day each week — with a family member checking the work — reduces both missed doses and double dosing.
Pre-packaged blister cards from pharmacies (sometimes called bubble packs or strip packaging) are filled by the pharmacist and delivered weekly or monthly. They are a meaningful reliability upgrade over patient-filled organizers, especially for adults with mild cognitive impairment. Many independent pharmacies offer this for free or a small fee, and mail-order pharmacies and PACE programs commonly include packaging.
Automated medication dispensers — such as Hero, MedMinder, and similar devices — store weeks of medication and dispense doses at scheduled times with audible alerts. Some send notifications to family caregivers when a dose is missed. Costs typically run about $30 to $100 monthly depending on features. They can be useful for moderate cognitive decline or when a family caregiver needs remote oversight.
For complex injection regimens (insulin, GLP-1 agonists, biologics), pharmacist or visiting-nurse training, large-print instructions, and pre-filled pens reduce error. Continuous glucose monitors with smartphone alerts are now Medicare-covered for many insulin users and can substantially improve safety by catching lows early.
Deprescribing
Deprescribing is the planned, supervised reduction or cessation of medications that may be causing more harm than benefit. The Bruyere Deprescribing Guidelines provide evidence-based protocols for tapering benzodiazepines, proton pump inhibitors, antipsychotics used in dementia, opioids, and others. The goal is not the fewest possible medications — it is right-sized medication for the person’s goals and life expectancy. Crucially, deprescribing is clinician-led: never stop or taper a medication on your own, because abrupt discontinuation of drugs such as benzodiazepines, beta-blockers, or certain antidepressants can be dangerous.
Common deprescribing targets in older adults include long-term proton pump inhibitors without ongoing reflux disease, sleeping pills (Z-drugs and benzodiazepines), anticholinergics, statins in patients with very limited life expectancy, and blood-pressure medications that have driven readings too low for a frail older adult. Any change should be made gradually and monitored by the prescriber.
High-Risk Drug Categories
Anticoagulants — warfarin, apixaban, rivaroxaban, dabigatran — raise bleeding risk in older adults but often substantially reduce stroke and clot risk. In atrial fibrillation the benefit usually outweighs the risk, but routine fall-risk assessment, monitoring, and awareness of reversal agents matter. A fall with head injury while on an anticoagulant warrants urgent ER evaluation for bleeding around the brain.
Glucose-lowering drugs, particularly long-acting sulfonylureas (glyburide, glimepiride) and aggressive insulin regimens, can cause low-blood-sugar episodes that present as falls, confusion, or “stroke-like” events. The 2023 Beers Criteria specifically advise against long-acting sulfonylureas in older adults. Looser glycemic targets (for example an A1c around 7.5 to 8.5 percent) are appropriate for many frail older adults, per AGS and diabetes-society guidance — but targets are individualized by the clinician.
CNS-active medications — benzodiazepines, opioids, anticholinergics, and sedating antihistamines — increase falls, delirium, and cognitive impairment. Our fall prevention guide covers screening tools that incorporate medication review.
Cardiovascular and other drugs that require dose adjustment for kidney function are sometimes used at full adult doses despite a low eGFR. Hospital admissions for digoxin toxicity, acute kidney injury from the “triple whammy” (an ACE inhibitor or ARB plus a diuretic plus an NSAID), and bleeds from anticoagulants dosed too high are recognized, largely preventable problems that a careful medication review can catch.
When to seek emergency care: Call 911 or go to the emergency room for severe medication adverse events: confusion or altered consciousness in someone with diabetes (suggesting low blood sugar), blood in vomit or stool while on an anticoagulant, severe weakness or fainting, signs of an allergic reaction (hives, swelling, breathing difficulty), or sudden new neurologic symptoms after a medication change. Bring the medication list to the ER. For a suspected medication error, wrong dose, double dose, or possible poisoning — when the person is awake and not in distress — call Poison Control (Poison Help) at 1-800-222-1222, which is staffed 24/7 and free. If the person is unconscious, not breathing, seizing, or otherwise in crisis, call 911 first.
Caregivers and Coordination
One designated care coordinator — typically an adult child or spouse — should hold the master medication list. Updating it after every doctor visit, hospital discharge, or pharmacy change keeps everyone aligned. Apps such as CareZone, Medisafe, and the official Medicare app can help, but a single up-to-date printed list in the wallet remains one of the most useful things to have in an emergency.
Hospital transitions are a peak-risk window. Discharge medication lists frequently differ from the home regimen, and reconciliation errors are common. Asking the discharging team to compare the new list against the prior home list, line by line, prevents many errors. Involving the community pharmacist in that reconciliation adds another safety check, since pharmacists often see the full picture across prescribers.
Frequently Asked Questions
How can I tell if my parent is taking medications correctly?
Ask to see the bottles. Fill dates that do not match the dosing schedule can signal under- or over-use. Counting pills against the expected number remaining is a quick check. You can also ask the pharmacist to run a refill history — most will share it with the patient or an authorized caregiver.
Are pill organizers safe to share between siblings or housemates?
No. Each person needs their own clearly labeled organizer. Mixing increases the risk of accidental ingestion, particularly when one person takes narcotics or anticoagulants the other does not.
What is the most common medication mistake in older adults?
Duplications across specialists — for example, two different proton pump inhibitors from a primary care doctor and a gastroenterologist, or two different sleeping aids. An annual brown-bag review with all bottles present catches the large majority of these.
Should seniors avoid taking supplements?
Not categorically — many supplements are reasonable. But supplements can interact with prescription medications (St. John’s wort, fish oil, ginkgo, and vitamin K are common examples) and should be on the same medication list a clinician reviews. Many “natural” products are not benign when combined with prescriptions.
What number do I call for a medication mistake?
For a suspected wrong dose, double dose, or accidental ingestion when the person is awake and stable, call Poison Control at 1-800-222-1222 — it is free, confidential, and staffed 24 hours a day. Call 911 for any emergency such as loss of consciousness, trouble breathing, or seizures.
Quick summary: Polypharmacy is common after 65 and drives a large share of avoidable harm. The best safeguards are an annual brown-bag review with a doctor or pharmacist, matching a delivery tool (organizer, blister pack, or automated dispenser) to the person’s cognition, attention to the AGS 2023 Beers Criteria, and clinician-led deprescribing of what is no longer needed. Never stop or change a medication on your own. For a suspected medication error, call Poison Control at 1-800-222-1222; call 911 for an emergency.

The Bottom Line
Medication safety is one of the most modifiable risks in older-adult care. An annual brown-bag review, the right delivery tool (pillbox, blister pack, or automated dispenser) matched to the person’s cognition, attention to Beers Criteria flags, and a willingness to deprescribe what is no longer needed can prevent hospitalizations, falls, and avoidable harm. Caregivers play an outsized role: keeping a current list, attending appointments when possible, asking pharmacists for medication therapy management reviews, and knowing the Poison Control number can change outcomes more than most single clinical interventions.
