Painkillers are among the most commonly used medicines in the world.
Millions of people take them every day to ease headaches, back pain, arthritis, injuries, and other painful conditions.
For many people, these medicines make daily life easier by helping them stay active and comfortable.
However, growing evidence suggests that some widely used pain-relieving drugs may have important health risks that should not be ignored.
Pain is a complex health problem. Acute pain, which happens after an injury or illness, often improves within days or weeks. Chronic pain, on the other hand, can last for months or even years.
Because chronic pain can affect sleep, work, and quality of life, many people rely on medications for long-term relief. Researchers are now taking a closer look at how these medicines may affect the body over time.
One major group of painkillers is called non-steroidal anti-inflammatory drugs, often shortened to NSAIDs. These medicines help reduce pain, swelling, and inflammation. Common examples include ibuprofen, naproxen, diclofenac, and several other drugs that are available by prescription or over the counter in many countries.
Researchers at the University of Alabama at Birmingham recently investigated the effects of carprofen, an NSAID, in animals that had heart disease. The study found that the drug caused low levels of inflammation in both the heart and the kidneys.
The problem became more serious when the animals experienced a heart attack. The findings suggest that NSAIDs could potentially worsen heart and kidney problems in people who already have underlying cardiovascular disease.
The research was published in the journal Life Sciences. Although animal studies do not always predict exactly what will happen in humans, they can provide important warning signs that help guide future medical research.
Another study focused on diclofenac, one of the most widely used NSAIDs worldwide. Researchers in Denmark analyzed health information from more than six million adults.
They discovered that people who started taking diclofenac had a higher risk of serious cardiovascular problems within the first 30 days of treatment. These problems included heart attacks, strokes, and irregular heart rhythms.
The researchers also found that the risk was higher than that seen in people taking other common NSAIDs, such as ibuprofen or naproxen.
It was also higher than the risk among people taking paracetamol, which is known as acetaminophen in some countries. These findings suggest that diclofenac may deserve extra caution, especially for people who already have heart-related risk factors.
The Danish study was published in The BMJ, one of the world’s leading medical journals. The researchers recommended that both doctors and patients carefully consider the benefits and risks before choosing diclofenac for pain treatment.
The concerns do not end with NSAIDs. Scientists are also studying other drugs commonly prescribed for long-term pain.
Researchers from Newcastle University in the United Kingdom examined medications known as gabapentinoids, including gabapentin and pregabalin, as well as opioid painkillers. These drugs are often used for nerve pain and more severe chronic pain conditions.
Using data from more than 133,000 participants in the UK Biobank project, the researchers found that people taking these medications were more likely to be obese and to report poor-quality sleep.
According to the researchers, some of these drugs can have sedative effects that reduce physical activity. Less movement during the day may contribute to weight gain over time.
The study also suggested that these medicines may affect appetite and food preferences. Some users may experience stronger cravings for sweet foods, which could further increase the risk of obesity. Excess weight is already linked to many health problems, including heart disease, diabetes, and high blood pressure.
The Newcastle University research was published in the journal PLOS ONE. The findings add to growing evidence that some pain medicines can affect more than just pain levels. They may also influence sleep patterns, body weight, and overall health.
Taken together, these studies highlight the importance of using painkillers carefully. While these medicines can provide valuable relief, they may also bring risks that become more significant with long-term use. People who already have heart disease, kidney disease, diabetes, or other chronic health conditions may need to be especially cautious.
Experts generally advise that pain medicines should be used at the lowest effective dose for the shortest time needed. Regular medical checkups can help identify possible side effects before they become serious.
In some situations, non-drug approaches may also help manage pain. These can include physical therapy, exercise programs, mindfulness techniques, and other supportive treatments recommended by healthcare professionals.
Pain management is often about finding the right balance between relief and safety. These recent studies remind us that every treatment has both benefits and risks. Understanding those risks can help patients and doctors make more informed decisions and choose the safest approach for long-term health.
