Joanne Lynn, MD, has lost track of the number of times in her 40 years as a geriatrician she’s seen a new patient come to her office carrying a bucket full of prescription medications – many of which they don’t need.
Dr. Lynn, who is on the faculty of George Washington University,Washington, recalled one woman who unwittingly was taking two blood pressure medications with different names.
“The risks included all the side effects overdosing carries,” Dr. Lynn said, ranging from blurred vision and crankiness to organ failure and even death.
For doctors with patients who don’t know they’re taking too much of a medication, “you wonder whether the drug is causing the health problems, and it’s a symptom of the wrong medication,” rather than a symptom of an undiagnosed illness, she said.
Patients often assume their health providers check for drug interactions or assess if a medication is no longer needed, and will catch extra prescriptions. That could be a risky assumption. Some doctors may prescribe yet another prescription to manage the side effects of an unnecessary drug, instead of doing a medication review and potentially “deprescribing” or discontinuing, a treatment that’s no longer needed.
About 57% of people age 65 years or older take five or more medications regularly – a concept known as polypharmacy, a study published in 2020 in the Journal of the American Geriatrics Society shows. While doctors prescribe drugs to help patients manage various ailments, as a list of medications grows, so do potential complications.
An older adult might forget to tell their doctor what they’re taking, or maybe they don’t even know what they’re taking or why, Dr. Lynn said.
“In some cases, a doctor just added a drug to treat something, not realizing they were already taking something else for it,” she said. “Of course, the situation of whether these patients can even afford all these drugs matters a lot, too.”
Some older adults may pick and choose which medications to take based on cost, not knowing which prescriptions are necessary, Dr. Lynn said.
Finding the ‘right balance’
Indeed, if given the option, up to 80% of older adults ages 50-80 would be open to stopping one or more of their prescribed medications, according to a 2023 poll by researchers at the University of Michigan, Ann Arbor.
“A lot of drugs that people take might have been appropriate at one point, but might have outlived their usefulness for that individual,” said Michael Steinman, MD, a professor of medicine and a geriatrician at the University of California, San Francisco, and coprincipal investigator of the U.S. Deprescribing Research Network, a doctor group focused on improving medication use for older adults.
“Having fewer medications can actually be beneficial,” he said. “You can take too many medications; you can take too few. The optimal thing is finding what is the right balance for you.”
Defining how many medications is too many depends on each person, which is why caregivers and older adults can ask their doctor for a review of medications that have multiplied over time.
By reevaluating their medications, older adults can actually lower their chances of potentially harmful side effects, and avoid the spiral of being prescribed even more medications, said Sarah Vordenberg, PharmD, MPH, a clinical associate professor at the University of Michigan’s College of Pharmacy, Ann Arbor.
“It’s not really the number of medications, it’s [about] are they inappropriate or unnecessary medications for a patient,” she said.
Patients and caregivers can ask for an honest conversation with their doctor. The University of Michigan poll found that more than 90% of older adults who took prescription medications expected their health care provider to review their medicines during a regular visit.
But doctors often need prompting from patients to start a review.
“The clinical inertia, or maintaining the status quo, unfortunately is a lot of times easier than having time-intensive conversations,” Dr. Vordenberg said.
