More Prescriptions, More Problems?
What Every Patient Should Ask
Half of all Medicare patients are on five or more prescription medications. Nobody knows if those combinations are safe. Here’s what you can do about it.
If you’re over 65 and taking a handful of pills every morning, you’re not alone. About half of all people on Medicare are currently taking five or more prescription medications. That’s a staggering number — and here’s the part that might surprise you: no one actually knows whether your specific combination of drugs is safe.
Not your doctor. Not your pharmacist. Not the pharmaceutical companies that made them. No one.
That’s not an opinion. That’s the reality of modern medicine, and it’s one that this Walk, Don’t Run to the Doctor podcast episode wants you to understand. Not to scare you. But to empower you.
“Your doctor is guessing…It’s important for you to realize it’s a guess.”
This isn’t an indictment of doctors. It’s a structural problem. The studies simply don’t exist. No clinical trial has ever tested the exact combination of medications sitting in your medicine cabinet right now on your body’s makeup, and no clinical trial ever will. When your doctor prescribes drug number four or five or six, they’re making their best educated guess based on what they know about each drug individually. But how those drugs interact inside your body, with your particular biology? That’s uncharted territory.
And that matters enormously.
Taking too many medications isn’t just inconvenient. It’s dangerous.
The Prescription Cascade
Polypharmacy (the medical term for taking multiple medications simultaneously) is associated with more falls, more memory loss, and more loss of independence. Often, the culprit is something called a prescription cascade, and it works like this: a doctor prescribes a medication for a legitimate problem. That medication causes a side effect. Instead of recognizing the side effect for what it is (a drug side effect), another medication gets prescribed to treat the new symptom.
In our practice just this past week, we prescribed a blood pressure drug for a man with hypertension. The drug caused erectile dysfunction. Now the patient is on medication for his erectile dysfunction, too. One pill became two, each carrying its own set of potential side effects, each interacting with the other in ways that haven’t been studied.
Multiply that scenario across five, seven, or eleven medications, and you begin to see the problem. You’re not taking a carefully designed treatment plan. You’re living inside a chemical soup — and nobody designed the recipe.
It gets worse when you factor in over-the-counter medications. Tylenol, ibuprofen, allergy pills, sleep aids — most people don’t even think of these as “real” medications, but they absolutely are. They interact with prescription drugs. They carry their own side effects. And they add more unknowns to an already unknown equation. Each comes with a package insert (also found on labels.fda.gov) that you should read before swallowing that pill.
The Drugs You Should Be Most Worried About
Not all medications carry equal risk as we age. Two categories deserve special attention: anything with sedative properties, and a large group known as anticholinergic medications. These drugs (which include certain allergy medications, bladder medications, and antidepressants), are particularly problematic in older adults because they can cause confusion, drowsiness, falls, and cognitive decline.
There’s a resource that can help you identify whether you’re taking any of them. It’s called the Beers List, and it’s a regularly updated, publicly available document that catalogs medications best avoided in people over 65. You can download it from the internet, bring it to your next doctor’s appointment, and have a real conversation about whether anything you’re taking appears on that list.
That conversation is not one your doctor will resent.
I don’t know a doctor on the planet that isn’t delighted to get you off of medications if you don’t need them anymore. If you don’t have high blood pressure anymore, you don’t need the medications anymore.
What if the Better Answer Isn’t a Pill?
Here’s the part that most people never hear from their doctor — not because doctors don’t believe it, but because a fifteen-minute appointment doesn’t leave time to say it: many of the conditions driving those prescriptions can be improved or even reversed through lifestyle changes.
Take blood pressure, for example. If you lost ten or fifteen pounds, ate more vegetables, and got some exercise every day, you might not need that medication at all. The same is often true for type 2 diabetes, for high cholesterol, for a host of conditions that get managed with pills when they could be managed (or eliminated!) with food and movement.
This isn’t wishful thinking. It’s what we’ve seen in practice for decades. And Judy’s health story makes the case more powerfully than any statistic.
