Ibuprofen is one of the most commonly used medicines in the world. Millions of people take it every day to reduce pain, swelling, or fever.
It is sold in supermarkets, pharmacies, and convenience stores, and many people use it without thinking much about possible risks. People often take ibuprofen for headaches, back pain, muscle soreness, arthritis, toothaches, and common illnesses such as colds or the flu.
Because it is so easy to buy, many people assume ibuprofen is completely safe when used regularly. However, new research from the University of California Davis suggests that this popular medicine may affect the body in ways scientists did not fully understand before.
The study found that ibuprofen may place stress on the liver and may even affect males and females differently.
Ibuprofen belongs to a group of medicines called nonsteroidal anti-inflammatory drugs, also known as NSAIDs. Other medicines in this group include naproxen and aspirin. These drugs work by reducing chemicals in the body that cause pain and inflammation.
Doctors have long known that NSAIDs can sometimes increase the risk of heart problems, stomach bleeding, and strokes, especially when used often or in high doses. But scientists have not studied their effects on the liver as closely.
The liver is one of the most important organs in the body. It helps clean harmful substances from the blood, stores energy, processes nutrients from food, and breaks down medicines. Since the liver handles many drugs we take, scientists wanted to understand how ibuprofen changes liver function over time.
In the new study, researchers gave mice a dose of ibuprofen similar to what a human might take, about 400 milligrams a day, for one week. After that, they carefully examined the liver cells of the mice to see what had changed.
The researchers discovered major changes in how the liver worked, especially in male mice. At least 34 important systems inside the liver were affected.
These systems are involved in managing vitamins, hormones, amino acids, and many other essential body functions. This suggests that ibuprofen may have a much broader effect on the body than scientists previously realized.
The study also found that ibuprofen increased levels of hydrogen peroxide inside cells. Hydrogen peroxide is a chemical that can damage proteins and place stress on cells if too much builds up. When this happens, the liver may need to work harder to repair the damage and keep the body healthy.
One of the most surprising discoveries was that ibuprofen affected males and females differently. In some cases, the effects were almost completely opposite.
For example, a structure inside cells called the proteasome behaved differently in male and female mice after taking ibuprofen. The proteasome acts like a cleanup system that removes damaged or unwanted proteins from cells.
This finding suggests that the same medicine may not affect every person in the same way. Scientists believe biological differences between males and females may change how the body processes drugs, which could influence both benefits and side effects.
The researchers also found that ibuprofen could change how long other medicines remain inside the body. This effect was especially noticeable in male mice. If medicines stay in the body longer than expected, they may build up to unsafe levels and increase the risk of side effects or harmful drug interactions.
Because of these findings, the researchers say people should use ibuprofen more carefully, especially for mild pain that may improve naturally over time. They also believe doctors and scientists should pay closer attention to the different ways medicines affect men and women.
The study highlights a growing idea in modern medicine called personalized treatment. Instead of using the same treatment for everyone, doctors may one day tailor medicines based on a person’s biology, sex, age, or health condition. This approach could help make treatments safer and more effective.
Researchers are also studying other ways to manage pain naturally or with fewer risks. Some studies suggest that drinking water with electrolytes may help reduce muscle pain after exercise.
Other research has raised questions about whether some over-the-counter pain medicines could make illnesses such as COVID-19 worse in certain situations.
The new research was led by Professor Aldrin Gomes and published in the journal Scientific Reports. The study reminds us that even common medicines can have hidden effects inside the body.
Ibuprofen can still be very helpful for pain and fever, but scientists say it is important for people to understand both the benefits and the risks.
As researchers continue learning more about how medicines affect the body, it is becoming clear that healthcare may move away from a one-size-fits-all approach. Understanding how different people respond to the same drug could help make treatments safer for everyone in the future.
