Ask a family caregiver what medications their mother takes and most can recite the list from memory. Ask who last reviewed that list as a whole — not one drug at a visit, but all of it together, asking whether each item is still needed — and the answer is usually silence.
That gap is one of the most consequential in older-adult care, and closing it is something a family can actually initiate. It does not require a new specialist or a diagnosis. It requires a list, an appointment, and a specific request.
How the List Gets Long
Nobody sets out to put an eighty-year-old on eleven medications. It accumulates, and the mechanism is almost always the same.
A cardiologist adds something. A year later a rheumatologist adds something else, unaware of the first. A hospital stay introduces two more, and the discharge summary says to continue them without saying for how long. A drug prescribed to counteract a side effect becomes permanent after the original drug is stopped. Nobody is negligent; there is simply no one whose job is the whole list.
The term for this is polypharmacy — generally defined as five or more regular medications. It's associated with higher rates of falls, hospitalization, cognitive impairment, and adverse drug events, and the risk climbs with each addition. A related phenomenon, the prescribing cascade, is worth knowing by name: a side effect gets treated as a new condition, and a second drug is added to manage the first.

The Drugs That Deserve the Most Scrutiny
Some categories carry disproportionate risk in older adults, particularly those with cognitive impairment. You don't need to know the pharmacology — you need to know which items to ask about.
Anticholinergics. A large and surprising category: some bladder medications, older antihistamines, certain antidepressants, some sleep aids. They impair memory and cognition, reduce sweating, and raise fall risk. Cumulative anticholinergic burden is associated with worse cognitive outcomes, and many of these are available over the counter.
Benzodiazepines and “Z-drugs.” Prescribed for anxiety or sleep, frequently continued for years. They substantially increase fall and fracture risk and worsen confusion. Stopping them requires a slow, supervised taper — never abruptly.
Antipsychotics. Sometimes used for dementia-related agitation. They carry a boxed warning for increased mortality in older adults with dementia and interfere with temperature regulation, which matters a great deal in an Arizona summer. Legitimate in specific circumstances; worth revisiting regularly.
Proton pump inhibitors. Often started for a short course and continued indefinitely. Long-term use is associated with nutrient malabsorption and infection risk.
Blood pressure medications. Not inherently problematic, but targets appropriate at sixty may cause dangerous drops on standing at eighty-five. Over-treatment is common and directly causes falls.
Anything for a condition the person no longer has, or a preventive medication whose benefit horizon exceeds the person's likely lifespan. This is a legitimate, humane conversation to have.
Running the Review
The practical work is unglamorous and effective.
Build a true list first. Not from memory. Gather every bottle in the house — prescriptions, over-the-counter, vitamins, supplements, topicals, eye drops, anything used “as needed.” Bag them and bring them. Supplements matter: fish oil, St. John's wort, and high-dose vitamin E all interact with common prescriptions.
Record for each one: the drug, the dose, how often, who prescribed it, when it started, and what it's for. That last column is where families discover items nobody can explain.
Ask for a formal medication review. Use the words. Request that the prescriber — or a pharmacist, who is often better positioned for this — go through the entire list and answer, for each item: is this still indicated, is the dose still right for current kidney and liver function, and could this be contributing to falls, confusion, or appetite loss? Medicare's annual wellness visit and pharmacist-led medication therapy management are both existing routes for this.
Ask directly about deprescribing. It's a recognized clinical practice, not an unusual request. Reducing or stopping a medication is an intervention with its own evidence base, and many prescribers welcome the prompt.
Change one thing at a time. Stopping several drugs simultaneously makes it impossible to attribute what improves or worsens. Expect a staged plan over months.
Use one pharmacy. A single pharmacy sees the whole list and will catch interactions no individual prescriber can.
What Improvement Looks Like
Families are often startled by the results, because the symptoms they'd attributed to aging or to dementia turn out to have been partly pharmacological.
After a sleep aid or anticholinergic comes off, people are frequently more alert, steadier, and more engaged. Appetite returns when a drug causing nausea or dry mouth is removed. Fewer falls follow a blood pressure adjustment. None of this reverses dementia, and it's important not to promise that. But it can meaningfully change how well someone functions within it.
The corollary matters too: a new symptom in an older adult should prompt the question what changed recently in the medications? before it prompts a new prescription. That reflex prevents a great many prescribing cascades.
Why Oversight Beats Vigilance
A committed family can do a great deal of this. What's hard to sustain from outside is the ongoing part — noticing on a Tuesday that a resident has been slightly off since the dose changed, connecting it to the change, and getting it in front of the prescriber that week.
That's the practical argument for nurse-practitioner involvement in a care setting. Someone who knows a resident's baseline can see medication effects as they emerge rather than at the next scheduled appointment, and can bring the prescriber a specific, documented observation instead of a vague concern. We wrote about how that oversight works day to day in our post on falls and what actually prevents them, where the medication review is the highest-yield intervention of the whole list.
The bottom line
Bag every bottle in the house, build a list with a “what is this for” column, and ask a prescriber or pharmacist for a formal medication review and a deprescribing conversation. Pay particular attention to anticholinergics, benzodiazepines, antipsychotics, and blood pressure targets set decades ago.
It costs one appointment and it is among the highest-value things a family can do — often improving alertness, appetite, and steadiness more than anything added to the list ever did.
