Paracetamol is one of the most commonly used medicines in the world. Many people take it to relieve pain, reduce fever, or manage long-term conditions such as arthritis.
It is often seen as a safer choice compared to other painkillers, especially non-steroidal anti-inflammatory drugs, also known as NSAIDs.
However, a new study from the University of Edinburgh suggests that paracetamol may not be as harmless as many people believe, especially for those with high blood pressure.
High blood pressure, also called hypertension, is a serious health condition that affects millions of people. It often has no clear symptoms, but over time it can damage the heart and blood vessels.
This increases the risk of heart attacks, strokes, and other life-threatening problems. Because of this, people with high blood pressure need to be very careful about the medicines they take.
For many years, doctors have advised patients with high blood pressure to avoid NSAIDs when possible. This is because NSAIDs are known to raise blood pressure and increase the risk of heart problems. As a result, paracetamol has often been recommended as a safer option for pain relief.
However, the new research challenges this common belief. The study was carried out by researchers at the University of Edinburgh and was published in the medical journal Circulation. The research was led by Iain MacIntyre and included Professor James Dear as part of the research team.
In the study, the researchers looked at 110 people who already had a history of high blood pressure. The participants were divided into two groups. One group was given paracetamol, while the other group received a placebo, which is a treatment with no active medicine.
The group taking paracetamol received one gram of the drug four times a day. This is a dose that is often used for people who have chronic pain and need regular treatment. The study lasted for two weeks, allowing the researchers to observe any changes in blood pressure over time.
The results were clear. People who took paracetamol had a noticeable increase in their blood pressure compared to those who took the placebo. This finding is important because even a small increase in blood pressure can have serious effects over time.
The researchers explained that the rise in blood pressure seen in the study was similar to the increase caused by NSAIDs. Previous studies have shown that such increases in blood pressure can raise the risk of heart disease and stroke by around 20 percent. This means that long-term use of paracetamol could carry risks that were not fully understood before.
Professor James Dear pointed out that paracetamol is used by millions of people every day. Because of this, even a small increase in risk could affect a large number of people. He stressed that high blood pressure is one of the main causes of heart attacks and strokes, so anything that raises blood pressure needs to be taken seriously.
The findings suggest that doctors and patients should think more carefully about long-term use of paracetamol, especially in people who already have high blood pressure or heart disease. It does not mean that paracetamol should never be used, but it highlights the need to use it wisely.
The researchers recommend that people should take the lowest effective dose for the shortest possible time. This approach can help reduce potential risks while still providing pain relief. Patients should also talk to their doctors before using paracetamol regularly, especially if they have existing health conditions.
This study is important because it changes how we think about a very common medicine. For many years, paracetamol has been seen as a safe and simple option for pain relief. While it is still useful, this research shows that it is not completely risk-free.
As scientists continue to study the long-term effects of common medicines, it is important for people to stay informed and make careful choices about their health. By understanding both the benefits and the risks, patients can work with their doctors to find the safest and most effective treatment for their needs.
