Antibiotic Resistance: Painkillers’ Role in Supercharging It
- New research from the University of South Australia reveals that ibuprofen and acetaminophen (paracetamol) can increase bacterial resistance to antibiotics, with a compounded effect when taken together.
- Ibuprofen and acetaminophen (paracetamol) are common over-the-counter medications that many of us reach for when we're sick.
- In the first study of its kind, researchers found that ibuprofen and acetaminophen are not only driving antibiotic resistance when used individually but amplifying it when used together.

Common Painkillers might potentially be Fueling Antibiotic Resistance, Study finds

New research from the University of South Australia reveals that ibuprofen and acetaminophen (paracetamol) can increase bacterial resistance to antibiotics, with a compounded effect when taken together. This poses a significant risk, especially for vulnerable populations like those in aged care facilities.
The Link Between Painkillers and Antibiotic Resistance
Ibuprofen and acetaminophen (paracetamol) are common over-the-counter medications that many of us reach for when we’re sick. But new research from the University of South Australia shows that these trusted staples are quietly fuelling one of the world’s biggest health threats: antibiotic resistance.
In the first study of its kind, researchers found that ibuprofen and acetaminophen are not only driving antibiotic resistance when used individually but amplifying it when used together. The study, published in the journal eLife on August 27, 2024, investigated the interaction of these common painkillers with the broad-spectrum antibiotic ciprofloxacin and Escherichia coli (E. coli), a common bacteria causing gut and urinary tract infections.
Researchers discovered that both ibuprofen and acetaminophen substantially increased bacterial mutations in E. coli,leading to a heightened resistance to ciprofloxacin. The combined use of the painkillers resulted in an even more pronounced effect. University of South Australia News details the findings.
Implications for Aged Care
The findings are notably concerning for residents in aged care facilities. These individuals often receive multiple medications concurrently to manage various health conditions – a practice known as polypharmacy. This increases the potential for drug interactions and exacerbates the risk of antibiotic resistance.
“We need to carefully consider the risks of using multiple medications – particularly in aged care where residents are often prescribed a mix of long-term treatments,” stated lead researcher Dr. Janet Patterson, as reported by the University of South Australia. “This doesn’t mean we should stop using these medications, but we do need to be more mindful about how they interact with antibiotics – and that includes looking beyond just two-drug combinations.”
According to the World Health Organization (WHO), antibiotic resistance is one of the top 10 global public health threats facing humanity. The WHO estimates that 700,000 people die each year due to drug-resistant diseases, and this number could rise to 10 million by 2050 if no action is taken.
The Need for Further Research
The researchers are calling for more extensive studies to investigate drug interactions among individuals on long-term medication regimens.A deeper understanding of how commonly used medications impact antibiotic effectiveness is crucial.
The study highlights the importance of a holistic approach to medication management, considering not only the intended effects of each drug but also potential interactions with others. Pharmacists and healthcare providers play a vital role in identifying and mitigating these risks
