Modern medicine has transformed our lives – helped us to live longer, treat and manages diseases more effectively, and prevent disease from happening in the first place. From managing blood pressure to controlling chronic pain, prescription medications have helped millions of people live longer, healthier lives.
But there’s a growing concern in healthcare that often flies under the radar: overmedication, also known as polypharmacy.
For many people—especially older adults—taking multiple medications at once has become the norm. While each prescription may be appropriate on its own, the combination can sometimes do more harm than good.
That’s why regularly asking your doctor to review your medications isn’t just a good idea—it’s a critical part of protecting your health.
What Is Overmedication?
Overmedication typically refers to the use of more medications than are clinically necessary, or the use of medications where the risks outweigh the benefits.
Clinically, polypharmacy is often defined as taking five or more medications at the same time. This is increasingly common, particularly among older adults.
While multiple medications can be appropriate for managing complex conditions, the risk of complications rises significantly as the number of drugs increases.
The Hidden Risks of Multiple Medications
Taking several medications at once introduces a range of potential problems—many of which are not immediately obvious.
1. Drug Interactions
One of the biggest risks is drug-drug interactions.
Each medication affects the body in specific ways, but when combined, they can interact unpredictably. Some interactions reduce the effectiveness of a drug, while others can amplify side effects or create entirely new risks.
The likelihood of adverse drug interactions increases sharply with the number of medications a person takes.
2. Increased Side Effects
Every medication comes with potential side effects. When multiple drugs are involved, these effects can stack or overlap.
Common issues include dizziness, confusion, fatigue, and gastrointestinal problems. In older adults, these side effects can significantly increase the risk of falls, hospitalization, and loss of independence.
3. Prescribing Cascades
A particularly concerning phenomenon is the prescribing cascade.
This happens when a side effect from one medication is mistaken for a new medical condition, leading to the prescription of another drug. Over time, this can create a cycle where more and more medications are added—without addressing the root cause.
For example, a medication that causes swelling might lead to a prescription for a diuretic, which in turn causes electrolyte imbalances, prompting yet another medication.
4. Cognitive and Functional Decline
There is strong evidence linking polypharmacy to cognitive impairment, especially in older adults.
Certain medications—particularly those that affect the central nervous system—can impair memory, attention, and decision-making. A higher medication burden is also associated with increased risk of functional decline.
Why Overmedication Happens
Overmedication is never intentional. It often develops gradually over time due to several factors:
As a result, medications can accumulate without a clear reassessment of their ongoing value.
The Science Behind “Deprescribing”
To address this issue, clinicians have developed the concept of deprescribing—the systematic process of identifying and discontinuing medications that are no longer beneficial or may be harmful.
Deprescribing can lead to improved outcomes, including fewer falls, better cognitive function, and enhanced quality of life.
Importantly, deprescribing is not about stopping medications arbitrarily. It’s a careful, structured process done in collaboration with a healthcare provider. Never decide unilaterally to discontinue medications that you’ve been prescribed. Doctors welcome medication review and will engage in it very willingly.
Why Regular Medication Reviews Matter
Because our health needs change over time, medications should not be considered “set and forget.”
A periodic medication review allows your doctor to:
Regular medication reviews are especially important for older adults and those managing chronic conditions, but they can benefit anyone taking ongoing prescriptions.
Even for younger individuals, reviewing medications after major health changes—such as weight loss, new diagnoses, or lifestyle improvements—can be important. Imagin
How to Advocate for Yourself
Don’t wait for your doctor to bring it up. Be proactive and request a medication review once a year during an annual physical.
Here are a few simple steps:
Being actively involved in your care can lead to better health outcomes and safer treatment plans.
Medications are powerful and extremely valuable tools—but more isn’t always better.
Overmedication can quietly increase the risk of side effects, interactions, and long-term health complications. The good news is that many of these risks are preventable.
By regularly reviewing your prescriptions with your doctor, you can ensure that every medication you take is truly necessary, safe, and aligned with your current health needs.
Because when it comes to your health, the goal isn’t just treatment—it’s the right treatment.
