Paracetamol, a widely used over-the-counter painkiller, has long been considered a safe and reliable option for managing mild-to-moderate pain and fever. It is often the go-to treatment for conditions like osteoarthritis. However, a recent study has cast doubt on this long-standing perception, particularly for older adults. The study warns that repeated use of paracetamol could significantly increase the risk of gastrointestinal, heart, and kidney complications in individuals aged 65 and above.
New Research Uncovers Serious Health Risks
The study, conducted by researchers from the University of Nottingham in the UK, analyzed health records of over 180,000 older adults. These participants, aged 65 and older with an average age of 75, had been prescribed paracetamol more than twice within a six-month period. Their health outcomes were compared to a control group of over 400,000 individuals who had not been repeatedly prescribed the drug. The results were concerning, revealing a notable increase in the risk of several health issues. Key findings from the study include:
- A 24% higher risk of peptic ulcer bleeding (bleeding caused by ulcers in the digestive tract).
- A 36% increase in the likelihood of lower gastrointestinal bleeding.
- A 19% rise in the risk of developing chronic kidney disease.
- A 9% greater risk of heart failure.
- A 7% higher chance of developing hypertension (high blood pressure).
These results suggest that long-term use of paracetamol may not be as benign as previously thought, particularly for older adults.

Why Is Paracetamol Still Recommended for Osteoarthritis?
Paracetamol has traditionally been the first-line treatment for osteoarthritis, a chronic condition characterized by joint pain, stiffness, and swelling due to cartilage degeneration. It is considered safer than nonsteroidal anti-inflammatory drugs (NSAIDs), which carry risks of gastrointestinal bleeding and cardiovascular problems. However, this new research challenges the perceived safety of paracetamol, especially when used repeatedly over long periods.
Lead researcher Dr. Weiya Zhang from the University of Nottingham's School of Medicine emphasized the importance of reevaluating paracetamol’s role in pain management for older adults. He noted that while the pain-relieving effects of paracetamol are minimal, the potential risks associated with its long-term use may outweigh its benefits.
Understanding the Health Complications
Gastrointestinal Issues
The study found a significant link between paracetamol use and gastrointestinal bleeding. Peptic ulcers can lead to dangerous bleeding in the stomach or intestines, causing severe pain, fatigue, and potentially life-threatening complications.
Kidney Damage
Repeated use of paracetamol may impair kidney function, increasing the risk of chronic kidney disease. This condition can progress silently, leading to kidney failure if not managed early. Older adults are particularly vulnerable due to natural age-related declines in kidney function.

Heart Problems
Paracetamol was also associated with a higher risk of heart failure and hypertension. Heart failure occurs when the heart cannot pump blood efficiently, leading to symptoms like shortness of breath, fatigue, and swelling. Hypertension is a major risk factor for heart disease, stroke, and other serious complications.
A Call for Caution and Further Research
The study’s authors highlight the need for further research to confirm these findings. While paracetamol remains widely used and accessible, older adults and healthcare providers should approach its long-term use with caution. This is especially relevant for managing chronic conditions like osteoarthritis, where the benefits of pain relief must be weighed against the potential risks.
Dr. Zhang’s findings suggest that healthcare guidelines for older adults may need to be revised. Considering alternatives such as physical therapy, low-impact exercise, and lifestyle changes may offer safer strategies for pain management.
What Should Older Adults Do?
If you are an older adult or caring for someone aged 65 and above, here are a few steps to consider:
- Consult Your Doctor: Before using paracetamol regularly, discuss the potential risks with your healthcare provider.
- Explore Alternatives: Non-drug therapies like physical therapy, weight management, and gentle exercises like swimming or yoga can help manage pain.
- Monitor Symptoms: If you experience symptoms like stomach pain, unusual fatigue, swelling, or changes in blood pressure, seek medical attention promptly.
Bottomline: Rethinking Long-Term Paracetamol Use
While paracetamol remains a staple in pain management, this study serves as a wake-up call for both patients and healthcare providers. For older adults, the risks of gastrointestinal bleeding, kidney damage, and heart complications may be significant enough to warrant a closer look at alternative treatments. Responsible use, regular monitoring, and open discussions with healthcare professionals are key to maintaining health and safety.
