Why medication reviews matter more as people age

Medication lists tend to grow over time. That is not automatically a problem, but it does make safety more complicated. A new AARP guide on medication and supplement safety emphasizes a simple point: as people age, the chances of side effects, interactions and dosing mistakes can rise, especially when prescriptions are combined with over-the-counter products and supplements.

The message is less about avoiding medicines and more about using them carefully. Health authorities including the Food and Drug Administration and the National Institute on Aging say that age-related changes in the body, multiple chronic conditions and the use of several products at once can all increase the need for closer medication management. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/

What the new consumer guide is highlighting

AARP’s article is part consumer advice, part warning label. It walks readers through several common safety problems: taking too many products at once, misunderstanding directions, splitting pills incorrectly, missing drug interactions, and assuming supplements are harmless because they are sold without a prescription. The guide also points readers toward medication reviews, deprescribing conversations and practical ways to keep an up-to-date list of everything being taken. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/

The story lands at a moment when medication management remains a major issue in routine care. The AARP piece cites survey data showing many older adults take several prescription medicines, and it notes that supplements may not always be included in those counts. That matters because supplements can change how drugs work, add to side effects or duplicate ingredients already found in other products. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/

Why it matters

For many people, the biggest risk is not one dramatic mistake but a slow buildup of small ones. A medicine that once worked well may become more likely to cause dizziness, confusion, fatigue or falls when taken with other drugs or after a change in health status. The FDA says physical changes that come with aging can affect how the body handles medicine, while NIA says older adults often have multiple conditions and take several medications at the same time, which can alter how those medicines work. https://www.fda.gov/consumers/consumer-updates/5-medication-safety-tips-older-adults?source=govdelivery

That is one reason clinicians talk about polypharmacy, a term commonly used when a person takes five or more medications. It does not automatically mean treatment is inappropriate, but it does signal that the regimen deserves a closer look. AARP and NIA both point to medication reviews as a way to spot unnecessary drugs, overlapping ingredients, or products that should be tapered rather than stopped suddenly. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/

What the evidence actually shows

The strongest evidence behind the article’s advice is straightforward: when people use more drugs, the opportunity for drug-drug and drug-supplement interactions goes up. FDA consumer guidance says supplements can interact with medications and can interfere with lab tests or cause problems around surgery. NIA similarly warns that taking more than one product with the same active ingredient can lead to serious harm, including liver injury. https://www.fda.gov/ForConsumers/ConsumerUpdates/ucm050803.htm

Evidence also supports the value of medication reviews and deprescribing efforts, though the results are not perfect. A recent JAMA Internal Medicine editorial described a trial in which electronic medical record prompts combined with pharmacist stewardship led to a modest increase in deprescribing among hospitalized older adults, but the effect did not persist after part of the intervention ended. A separate JAMA Network Open systematic review found that multidisciplinary medication programs in emergency departments were associated with better deprescribing of potentially inappropriate medications, while also noting that these programs did not clearly improve hospital outcomes. https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2856164

That distinction matters. These studies do not prove that every medication review will prevent harm, and they do not mean a person should stop a medicine on their own. They do suggest that structured review, pharmacist involvement and decision support can improve prescribing quality in some settings. https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2856164

What remains uncertain

Not every side effect is caused by a medication, and not every symptom after a new prescription means the drug is the culprit. Fatigue, sleep changes, lightheadedness and confusion can have many causes. That is why experts recommend looking at the full picture rather than blaming one product too quickly. The evidence base also varies by drug class, setting and patient population, so a strategy that works in a hospital may not translate directly to a routine office visit. https://www.nia.nih.gov/health/medicines-and-medication-management/taking-medicines-safely-you-age

Supplement safety is especially murky. The NIH says dietary supplements do not have to be approved by the FDA for safety or effectiveness before they are sold. That does not mean every supplement is unsafe, but it does mean consumers should not assume that a bottle labeled “natural” is automatically benign. https://www.nia.nih.gov/health/vitamins-and-supplements/dietary-supplements-older-adults

What to discuss with a clinician

The most practical step is also the most basic: keep one current list of everything being taken, including prescriptions, over-the-counter medicines, vitamins and herbal products. Bring it to appointments and update it whenever a drug changes. The FDA and NIA both recommend that people ask how and when to take medicines, check for interactions and avoid sharing prescriptions with others. https://www.fda.gov/consumers/consumer-updates/5-medication-safety-tips-older-adults?source=govdelivery

It can also help to ask whether a medication review is appropriate if a regimen has become hard to manage, if there are multiple prescribers, or if new symptoms began after a medication change. AARP notes that deprescribing conversations may be useful when a drug is no longer needed or when a safer option exists. If a medicine is changed, patients should not alter the dose or stop abruptly unless a clinician has explained how to do so safely. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/

For people who have been told a medication or supplement has been recalled, the safest first step is to verify the specific product and lot number rather than stopping everything automatically. AARP and FDA both stress that recalls are often limited to certain manufacturers or batches. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/

The bottom line

The latest AARP guide does not argue that aging and medications are incompatible. It argues that the margin for error narrows when several drugs and supplements are in play. That makes medication lists, pharmacist checks and regular reviews more valuable—not because people should be alarmed, but because safer use often depends on noticing small problems before they become larger ones. If a new symptom feels urgent, or if someone has trouble breathing, severe confusion, fainting or signs of an allergic reaction, seek medical care right away. https://www.aarp.org/health/drugs-supplements/medication-safety-after-50/
