Prime Highlights:
- Medicines are ending up in rivers, soil, and wildlife, causing harm to the environment.
- A new roadmap by UK researchers shows ways to reduce pharmaceutical pollution and protect health and nature.
Key Facts:
- Only about 27% of people in the UK return unused medicines to pharmacies as recommended.
- Contraceptive hormones in rivers can feminize male fish, while antidepressants can alter fish behavior, making them more vulnerable to predators.
Background:
Medicines are vital for health, but they are ending up in rivers, soil, and wildlife, harming the environment. A new study by the University of Exeter shows how the UK and other countries can reduce medicine pollution.
The research included 48 experts from businesses, government, universities, and charities. Using the UK as a case study, the team identified 37 potential intervention points that could support long-term mitigation efforts. According to the first author, Kelly Thornber, “Pharmaceuticals are deeply ingrained in our healthcare systems and society. Real-world change cannot rely on quick technological fixes alone. Our approach combines practical solutions with interventions targeting the underlying social factors, aiming for systemic, lasting change.”
Pharmaceutical pollution is already impacting ecosystems in the UK. Studies show that contraceptive hormones in rivers can make male fish develop female traits, and antidepressants can change fish behavior, making them easier to catch. The problem is made worse when people throw away unused medicines in sinks or toilets, when people are unaware of the risks, and when wastewater treatment plants do not remove all drugs. In the UK, only about 1 in 4 people return unused medicines to pharmacies as they should.
Senior author Charles Tyler highlighted the urgency of the issue: “Pharmaceutical pollution has been largely overlooked. Our findings demonstrate the need for a holistic approach to ensure a sustainable future for both healthcare and the environment.”
To drive practical action, Dr Thornber and Professor Tyler have co-founded the Pharma Pollution Hub, a registered charity aiming to connect research, policy, and practice to accelerate real-world solutions. The hub seeks to establish the UK as a global leader in sustainable pharmaceutical supply and use.
As people use more medicines around the world, this plan is an important step to reduce pollution and protect both health and the environment.
