Breakthrough study finds common $1.50 drugs may flush “forever chemicals” linked to cancer from the body. Do you have it at home?

Could a familiar pill hold the key to fighting one of today’s most persistent toxic threats? A new breakthrough study suggests that some widely prescribed medications—yes, the same millions of Americans already take—might do more than protect your heart.

Researchers have discovered that these drugs may also help flush out “forever chemicals,” the stubborn compounds that linger in our bodies and the environment for years. Known for their link to cancer, immune dysfunction, and hormonal disruption, these chemicals have long been considered nearly impossible to eliminate.

But this new finding offers a surprising glimmer of hope—and raises big questions about how everyday medications might play a role in detoxifying our systems.

The Swedish discovery that's catching global attention

Researchers in Sweden have discovered something remarkable about two common cholesterol medications that many Americans already know well.

In a small but promising study, scientists found that cholestyramine (brand name Questran) and colesevelam (sold as Welchol) could significantly reduce levels of cancer-causing PFAS chemicals in the human body.

The study tracked 10 adults in the Swedish town of Ronneby, where residents had been unknowingly exposed to extremely high levels of PFAS through contaminated municipal water.

After a week of taking cholestyramine, PFAS levels in participants' feces were 23 times higher than normal—suggesting the drug was actively flushing these chemicals out of their systems.

Even more encouraging was what happened during 12 weeks of taking colesevelam: blood tests showed PFAS levels fell by up to 38 percent, compared with just 2 percent during a period without medication.

“In groups with high levels of PFAS in the blood, medicines can be used to lower the levels and speed up the otherwise slow elimination, there is no doubt about that,” said Dr. Axel Andersson, a researcher at the University of Gothenburg.

The science behind the breakthrough

The medications work as bile acid sequestrants—they bind to bile acids in the digestive tract to prevent reabsorption into the bloodstream. Researchers believe this same mechanism may prevent PFAS chemicals from being reabsorbed after the body attempts to excrete them.

This process, called enterohepatic recirculation, may be one reason why PFAS chemicals persist so stubbornly in human bodies. By interrupting this cycle, the cholesterol medications might provide an escape route for these persistent toxins.

Important limitations and cautions

Before you rush to your primary care physician (PCP), there are significant caveats to consider.

The Swedish study involved only 10 people and lasted just a few months. The researchers emphasized that much larger, longer-term studies are needed to confirm these results and establish safety protocols.

Both medications can cause side effects, particularly digestive issues like constipation, nausea, and stomach pain. In rare cases, serious complications, including pancreatitis, have been reported with colesevelam.

Most importantly, doctors stress these medications should not be taken by people without high cholesterol unless prescribed for a specific medical condition. The potential benefits of PFAS reduction must be weighed against medication risks, especially for older adults who may be taking multiple medications.

Why this matters especially for seniors

Recent estimates indicate that over 90% of Americans carry detectable levels of PFAS—synthetic compounds known for their persistence—in their bloodstream. These chemicals have made their way into everyday life through products like nonstick pans, water- and stain-resistant textiles, and grease-repellent food wrappers, slowly seeping into the body over time.

While these substances became deeply embedded in consumer and industrial use, comprehensive restrictions lagged behind. Only in recent years has regulatory action gained momentum, with the Environmental Protection Agency (EPA) setting new limits for PFAS in drinking water and proposing bans on certain types.

For Americans over 60, this issue is especially relevant. This generation has had the longest cumulative exposure to PFAS through everyday household items and occupational environments.

What’s at stake for your health

The health risks associated with PFAS—often called “forever chemicals”—are increasingly alarming.

Scientific studies have connected these substances to a range of serious conditions, including certain types of cancer, reproductive challenges, metabolic disorders like diabetes, and weakened immune responses.

In a major development in 2023, the International Agency for Research on Cancer, part of the World Health Organization, officially classified PFOA as a known human carcinogen and PFOS as possibly carcinogenic.

These findings reinforce growing concerns about long-term exposure and the urgent need for stronger safeguards.

Looking ahead: Hope and realistic expectations

For now, this Swedish research represents genuine hope but not yet a proven treatment. If you're concerned about PFAS exposure, the most important step is discussing your individual circumstances with your PCP. They can help you weigh the potential benefits against the risks and determine if these medications might be appropriate for your specific situation.

The research also underscores why supporting stronger PFAS regulations matters. While we wait for more definitive studies, continuing to push for comprehensive PFAS restrictions—like those proposed in Europe—remains crucial for protecting future generations.

Key Takeaways

• Study results: In people exposed to high PFAS levels: Cholestyramine increased PFAS excretion in feces by 23 times. Colesevelam reduced blood PFAS levels by up to 38% over 12 weeks.
• Why it matters: PFAS are linked to cancer, immune dysfunction, hormonal disruption, and other serious health risks. They’re found in nonstick cookware, stain-resistant fabrics, food packaging, and firefighting foam.
• Older adults at higher risk: Americans over 60 have had decades of exposure and may carry higher PFAS body burdens due to long-term accumulation.
• Limitations: The study was small (10 participants) and short-term. Experts caution that larger trials are needed, and these medications should not be used off-label without medical supervision.
• Bottom line: This research offers hope, but it’s not a green light for self-treatment. Talk to your primary care provider (PCP) before considering any medication for PFAS exposure.
