That bottle of allergy medicine or nighttime pain reliever sitting quietly in your home medicine cabinet might not be as harmless as its over-the-counter label suggests. Across the country, many older adults regularly use common over-the-counter medications without realizing that natural aging processes, chronic health conditions, and potential interactions with prescription drugs can drastically change how their bodies process and respond to these substances.
According to guidelines from the Food and Drug Administration, normal physiological shifts—such as changes in kidney and liver function and other age-related factors—can alter the way medications work in the body. Familiar products that have been used for decades can suddenly cause unexpected dizziness, cognitive confusion, digestive bleeding, or other serious health complications, particularly when combined with existing prescription regimens.
To help address these concerns, the American Geriatrics Society’s Beers Criteria identifies specific medications that adults aged 65 and older may need to avoid or use with heightened caution, depending entirely on their individual health circumstances. Health experts emphasize that these recommendations are not a blanket prohibition on these products, nor are they equivalent to a formal FDA product recall or a newly issued emergency safety warning. Instead, they serve as a critical clinical resource. For retirees who are carefully watching both their overall health and their mounting healthcare expenses, reviewing these eight common medications could help prevent unnecessary, out-of-pocket purchases and potentially costly, dangerous medical complications down the road.
Diphenhydramine, widely recognized by brand names like Benadryl and various nighttime pain relievers or over-the-counter sleep aids, is a first-generation antihistamine that frequently appears on safety watchlists. The American Geriatrics Society recommends that most older adults avoid its routine use because its strong anticholinergic effects can directly contribute to confusion, severe constipation, dry mouth, and a significantly increased risk of accidental falls. An older adult taking a nighttime medication containing diphenhydramine often experiences lingering drowsiness well into the following morning, making daily activities such as driving an automobile or navigating stairs considerably more hazardous. The Health in Aging Foundation points out that newer, non-sedating antihistamines and non-drug sleep strategies are available alternatives that are well worth discussing with a qualified healthcare professional. Before purchasing yet another sleep aid, consumers are advised to check whether they are already taking a medication that contains diphenhydramine and to consult a pharmacist about safer approaches.
Another category of concern involves traditional over-the-counter pain relievers such as ibuprofen and naproxen, which are sold under familiar brand names like Advil, Motrin, and Aleve. These drugs belong to a widespread class of medications known as nonsteroidal anti-inflammatory drugs, or NSAIDs. Although these products can effectively relieve acute pain and inflammation, prolonged and unsupervised use can significantly increase the risk of gastrointestinal bleeding, acute kidney injury, and worsening blood pressure control, particularly among older populations. The American Geriatrics Society strongly advises against the chronic oral use of NSAIDs in many older patients unless alternative therapies have proven ineffective and appropriate medical protective measures are put in place. Individuals who are concurrently taking blood thinners, corticosteroids, or other specific medications face even higher risks of complications, making a comprehensive review by a pharmacist especially crucial. Patients are encouraged to ask whether topical treatments, physical therapy, or alternative pain-management strategies might be appropriate instead of repeatedly purchasing oral pain relievers that only mask symptoms without addressing the underlying problem.
Proton pump inhibitors, commonly referred to as PPIs like Prilosec, Nexium, and Prevacid, are another group of medications that require careful evaluation. While these drugs effectively reduce stomach acid and serve as successful treatments for frequent heartburn and specific gastrointestinal conditions, the American Geriatrics Society advises against routine scheduled use beyond an initial eight-week period for many older adults unless a clear medical necessity supports continued treatment. The primary medical concerns involve established associations with complications such as severe intestinal infections and bone-related issues, although an individual patient’s actual risk always depends on their unique health background. Over-the-counter PPI formulations are generally intended for a short, 14-day treatment course, and any repeated or long-term use should be discussed thoroughly with a healthcare professional. If a consumer has been purchasing heartburn medication month after month, experts recommend evaluating whether the treatment is still necessary, whether an alternative approach would be more effective, and whether continued use is medically justified.
Decongestants containing pseudoephedrine and oral phenylephrine also deserve special attention, particularly for older adults who are managing high blood pressure, heart disease, or other underlying cardiovascular conditions. Pseudoephedrine has the known capability to increase both blood pressure and heart rate, making it essential to consult a pharmacist before utilizing any products containing this active ingredient. Oral phenylephrine presents a slightly different regulatory scenario, as the FDA has proposed removing it from the over-the-counter monograph for nasal decongestants after reviewing scientific evidence and determining that it is not effective at recommended doses. That particular regulatory proposal was based on a lack of proven clinical effectiveness rather than a new discovery that oral phenylephrine is inherently unsafe at standard labeled doses. Before spending money on multi-symptom cold formulations, consumers are advised to read the Drug Facts label carefully and ask whether simple saline sprays or other targeted treatments might manage their symptoms without introducing unnecessary active ingredients.
Doxylamine, another first-generation antihistamine, is frequently found in over-the-counter sleep aids and certain nighttime cold and flu remedies under brand names like Unisom. Much like diphenhydramine, doxylamine carries potent anticholinergic properties that can induce confusion, dry mouth, constipation, and prolonged, lingering daytime drowsiness in older individuals. Because of these distinct physiological concerns, the Beers Criteria explicitly includes doxylamine among the medications that are generally recommended for avoidance in adults aged 65 and older. A retiree who inadvertently takes an over-the-counter sleep aid alongside a nighttime cold medicine risks combining multiple products that contain powerful sedating agents, thereby compounding the danger of unwanted side effects. When chronic sleeplessness becomes a persistent issue, healthcare providers suggest evaluating the root cause of the insomnia and exploring non-drug approaches such as cognitive behavioral therapy.
Bismuth subsalicylate, widely recognized by the brand name Pepto-Bismol, is a common remedy for occasional bouts of diarrhea, nausea, and general stomach upset, but its active salicylate component warrants careful consideration. Individuals who are already taking blood thinners, aspirin, or other interacting medications must consult a pharmacist to check for potential drug interactions before using it. Furthermore, patients with a documented history of gastrointestinal bleeding, ulcers, or pre-existing kidney problems may require additional medical precautions tailored to their specific clinical circumstances. Excessive or prolonged use of bismuth subsalicylate can contribute to salicylate-related toxicity symptoms, including persistent ringing in the ears, and ongoing digestive distress may actually point to an underlying medical condition that demands professional evaluation. Rather than repeatedly purchasing over-the-counter stomach remedies, patients should track how frequently their symptoms occur and discuss ongoing digestive problems with a healthcare professional who can offer an appropriate, targeted treatment plan.
Magnesium citrate, a common over-the-counter saline laxative, is frequently utilized for the short-term relief of occasional constipation. While it can be highly effective when strictly used according to package directions, individuals who suffer from impaired kidney function may experience significant difficulty in eliminating excess magnesium from their bloodstreams. Overuse or regular reliance on these products can quickly lead to systemic dehydration, severe electrolyte disturbances, and potentially dangerous elevations in magnesium levels, particularly among patients with chronic kidney disease. Older adults who struggle with frequent or chronic constipation are strongly encouraged to discuss their symptoms and complete medication lists with a healthcare professional instead of relying on repeated, self-directed laxative use. Depending on the underlying cause of the condition, simple adjustments to dietary fiber intake, fluid consumption, physical activity, or an alternative bowel regimen can often provide a much safer and more sustainable long-term solution.
Chlorpheniramine is yet another older generation antihistamine that frequently appears as an active ingredient in over-the-counter allergy tablets and complex multi-symptom cold medications. The American Geriatrics Society includes chlorpheniramine among the first-generation antihistamines that most adults over the age of 60 should actively avoid due to predictable anticholinergic side effects. These adverse reactions can encompass profound sedation, mental confusion, acute constipation, and urinary retention difficulties, which can be particularly troublesome for individuals who are already managing multiple complex health conditions and concurrent prescriptions. Organizations like the Health in Aging Foundation suggest discussing modern, second-generation antihistamines—such as loratadine or fexofenadine—or alternative non-pharmacological allergy treatments with a primary care physician or pharmacist. Because brand-name cold and allergy remedies frequently combine several potent active ingredients into a single dose, checking the fine print on the product label is an essential step in preventing the accidental duplication of medications that produce overlapping side effects.
While individual over-the-counter products often appear inexpensive when purchased in isolation, the cumulative cost of repeated purchases can quickly transform into a meaningful financial burden for retirees who are living on fixed incomes. For instance, an individual spending fifteen dollars each month on a commercial sleep aid and another twenty dollars on recurring heartburn treatments faces an annual expenditure of over four hundred dollars, even before accounting for essential prescription drugs or routine doctor appointments. More importantly, medication-related side effects such as dizziness, unexpected falls, gastrointestinal bleeding, or other systemic complications can easily result in costly emergency room visits, specialist consultations, and substantial out-of-pocket medical expenses.
Consulting a licensed pharmacist can help patients identify duplicate active ingredients, potentially unnecessary products, and hidden drug interactions that make a less expensive or clinically appropriate alternative worth discussing with a primary care physician. Healthcare professionals advise bringing a complete, up-to-date list of all prescription medications, over-the-counter remedies, herbal products, vitamins, and dietary supplements to every routine medication review, emphasizing that patients should never discontinue a prescribed medical treatment without professional guidance. The ultimate goal of these precautions is not to force older adults to abandon every familiar household remedy simply because they have reached a certain age, but rather to ensure that each product continues to serve a genuinely useful purpose, fits seamlessly into current health needs, and avoids introducing unnecessary risks into daily life.
