How many prescription drugs do you take each day?

As the U.S. population ages, a growing number of older adults are juggling multiple medications daily — a trend that scientists and doctors say reflects both advances in treating chronic disease and growing concerns about the risks of “polypharmacy.”

Polypharmacy is typically defined as taking five or more medications concurrently. While there’s no universally accepted cutoff, many studies use that threshold to measure exposure to multiple drugs. 

According to recent data, more than 40 percent of Americans aged 65 and older regularly take at least five prescription medications each day, and nearly one in five takes ten or more. Many of these drugs are prescribed to manage conditions such as high blood pressure, diabetes, arthritis, and heart disease — common health challenges in later life.

Risks linked to multiple medications

Research shows that while some polypharmacy is medically appropriate, an excessive number of prescriptions can have unintended consequences for older adults. Multiple studies have identified disturbing links between high medication counts and poor health outcomes:

• Increased adverse effects & hospitalizations — Older adults taking many medications face higher risks of drug–drug interactions, which can lead to falls, confusion, cognitive issues, and emergency visits. 
• Functional decline after illness — A recent study in BMC Geriatrics found that seniors discharged from hospitals on six or more medications showed slower recovery and reduced ability to perform daily activities independently. 
• Quality of life impacts — Especially among seniors with Alzheimer’s or related dementias, higher drug counts have been associated with more symptoms, more frequent hospitalizations, and a lower overall physical function.

Experts explain that age-related changes in liver and kidney function can make it harder for older bodies to process medications, increasing susceptibility to side effects and harmful interactions.

Why so many?

The prevalence of polypharmacy is driven in part by multimorbidity — the existence of multiple chronic conditions — which becomes more common with age. Nearly 40 percent of adults over 65 have two or more chronic illnesses, making multiple prescriptions a practical necessity for many. 

However, clinicians emphasize that not all polypharmacy is beneficial. Some medications started years earlier continue long after they’re necessary. Others are added to counteract side effects of existing drugs, a phenomenon known as a “prescribing cascade.” 

To address these concerns, healthcare providers increasingly advocate for:

• Regular medication reviews that assess the ongoing need for each drug.
• “Deprescribing” efforts to safely taper or stop medications that no longer benefit the patient.
• Better coordination among specialists to avoid duplicate or conflicting prescriptions.
