Older adults can avoid polypharmacy, the regular use of five or more medications at the same time, by taking an active role in reviewing their prescriptions, asking pointed questions at every appointment, and working with their healthcare team to eliminate unnecessary drugs. People 65 and older make up about 14% of the U.S. population but account for more than a third of all outpatient prescription spending, which means the default trajectory for most aging adults is toward more pills, not fewer.
Why Polypharmacy Is Worth Preventing
The risks of taking multiple medications go well beyond an inconvenient pill organizer. Adverse drug events are responsible for more than 30% of unplanned hospital admissions in people 75 and older. About one-third of community-dwelling older adults fall each year, and medications are a major driver: research shows a 14% increase in fall risk with each additional medication beyond four. Sedating or anticholinergic drugs, which include many sleep aids and bladder medications, nearly double the risk of a fall over the course of a year.
Falls are just the most visible problem. Each additional drug also increases the chance of drug-drug interactions, confusion, fatigue, appetite loss, and a general decline in quality of life that often gets attributed to “just getting older” rather than to the medications themselves.
Understand the Prescribing Cascade
One of the sneakiest ways medication lists grow is through something called the prescribing cascade. It works like this: a drug causes a side effect, but instead of recognizing it as a side effect, a doctor interprets it as a new condition and prescribes another drug to treat it. That second drug causes its own side effect, which prompts a third prescription, and so on.
A published case study in the Canadian Pharmacists Journal illustrates this clearly. A patient on a blood pressure medication developed swollen ankles, a known side effect of that drug. A second doctor interpreted the swelling as a new problem and prescribed two diuretics. The diuretics caused frequent urination, which a third doctor treated with a bladder medication. The bladder medication caused dry mouth, which was then treated with yet another drug. One side effect turned into four new prescriptions. Recognizing this pattern is one of the most powerful things you can do to keep your medication list short.
Request a Brown Bag Medication Review
The single most effective step you can take is to gather every medication you use, including prescription drugs, over-the-counter pills, vitamins, and supplements, put them in a bag, and bring them to your pharmacist or primary care provider for a comprehensive review. This is known as a “brown bag review,” and it’s specifically designed to catch problems like therapeutic duplication (two drugs doing the same job), drug-drug interactions, drug-allergy conflicts, and medications you may no longer need.
A Cochrane review found that systematic medication reviews involving a pharmacist working closely with a physician and the patient or caregiver led to substantial reductions in inappropriate prescribing through either medication substitution or discontinuation. Many pharmacies offer this service at no extra cost. If yours doesn’t, ask your primary care provider to schedule a dedicated appointment for it at least once a year.
Ask the Right Questions at Every Appointment
Before accepting any new prescription, ask your provider a short set of direct questions:
- What is this medication treating, and is it treating a new condition or a side effect of something I already take? This question alone can interrupt a prescribing cascade before it starts.
- Is there a non-drug alternative that could work instead? For many conditions common in older adults, lifestyle or behavioral approaches are effective first-line options.
- Can any of my current medications be reduced or stopped now that this one is being added? Doctors often add without subtracting, especially when multiple specialists are involved.
- What side effects should I watch for, and how will we know if this medication is working? Setting a clear timeline for re-evaluation prevents drugs from lingering on your list indefinitely.
The U.S. Department of Veterans Affairs recommends that anyone on more than four medications proactively raise the topic of deprescribing with their healthcare team. You don’t need to wait for your doctor to bring it up.
Explore Non-Drug Alternatives
For several conditions that commonly drive polypharmacy in older adults, non-drug options are not just available but preferred. Insomnia is one of the best examples. International guidelines recommend cognitive behavioral therapy for insomnia (CBT-I) as the standard first-line treatment, not sleeping pills. Behavioral therapy was ranked the most effective intervention in a large network analysis comparing 17 different treatments for insomnia in older adults. Sleep medications like benzodiazepines, by contrast, are associated with increased fall and hip fracture risk and are generally recommended only for short courses of two weeks or less.
Similar logic applies to mild-to-moderate high blood pressure (where exercise, dietary changes, and weight management can sometimes reduce or eliminate the need for medication), chronic pain (where physical therapy, movement, and structured exercise programs often outperform long-term pain drug use), and mild depression or anxiety (where talk therapy and regular physical activity have strong evidence). None of this means you should stop a medication on your own. But knowing alternatives exist gives you standing to ask your provider whether a non-drug approach could replace one of your prescriptions.
Fix the Fragmented Care Problem
One of the biggest structural drivers of polypharmacy is fragmented care. When you see a cardiologist, a rheumatologist, and a primary care doctor who don’t share records or communicate with each other, each one prescribes independently. Research identifies siloed health systems and inconsistent medication reconciliation between providers as major barriers to safe prescribing.
You can counteract this by designating one provider, typically your primary care doctor, as the central coordinator of your medication list. Every time a specialist adds or changes a medication, make sure your primary care provider knows. If your providers use the same electronic health record system, this happens somewhat automatically. If they don’t, you become the bridge. Keep an up-to-date written list of every medication, dose, and prescribing doctor, and bring it to every appointment. Strengthened communication between providers and patients’ care partners has been identified as one of the most important facilitators of accurate medication reconciliation.
Know What Deprescribing Looks Like
Deprescribing is the supervised, gradual process of tapering or stopping medications that are no longer needed, no longer effective, or causing more harm than benefit. It follows a structured approach: first, a full inventory of everything you take; then, an assessment of each drug’s ongoing benefit relative to its risk; and finally, a prioritized plan for which drugs to try stopping first, with monitoring for any withdrawal effects or return of symptoms.
Clinicians use validated screening tools to identify which medications are most likely to be inappropriate. The most widely used are the STOPP criteria, which flag drugs that may be harmful in older adults (like sleep medications used beyond two weeks), and the START criteria, which identify beneficial medications that might be missing. The latest version of these tools, published in 2023, includes 133 STOPP and 57 START criteria, reflecting how nuanced the process has become.
Deprescribing doesn’t mean stopping everything at once. It typically means removing one medication at a time, monitoring for a few weeks, and then reassessing. Many people who go through this process report feeling more alert, more stable on their feet, and generally better, sometimes for the first time in years. If you’ve been on the same roster of medications for a long time without anyone questioning whether each one is still necessary, it’s worth asking for a formal review.
