Millions Take This Popular Drug — But New Research Suggests It Could Raise Memory Loss Risk by Up to 40%

For years, it’s been sitting quietly in medicine cabinets, purses, and nightstands across America. Doctors prescribe it. Pharmacies dispense it daily. And millions of people take it without a second thought.

But now, new scientific research is raising serious questions about whether this widely used drug could be quietly increasing the risk of memory loss — and even dementia — especially when used long-term.

The numbers are alarming.

According to several large studies, people who regularly take this medication may face up to a 40% higher risk of developing cognitive decline or dementia compared to those who don’t.

And most people have no idea.

A Drug Many People Take for Years

This medication is often prescribed to treat common, everyday conditions — things like anxiety, sleep problems, bladder issues, allergies, or chronic pain. Because the symptoms it treats feel manageable, many people end up taking it for months or even years, assuming it’s safe.

In fact, some users don’t even realize they’re taking it regularly — it may be combined with other medications or sold under different brand names.

That’s part of what worries experts.

What the Research Is Showing

Recent studies following tens of thousands of adults over long periods of time found a troubling pattern:
people who used this drug frequently or for extended periods were significantly more likely to develop memory problems later in life.

Researchers believe the drug may interfere with a key brain chemical involved in learning, memory, and attention. Over time, this interference could contribute to long-term cognitive damage.

One study found that the longer the exposure, the higher the risk — meaning years of use appeared far more dangerous than short-term use.

Why This Is Especially Concerning for Older Adults

The risk seems to be highest among middle-aged and older adults, particularly those already vulnerable to memory issues.
