Irrational use of non-steroidal anti-inflammatory drugs (NSAIDS): clinical impacts, toxicological risks, and the role of pharmaceutical care in promoting rational use
This integrative review highlights the severe clinical and toxicological risks associated with the widespread irrational use of NSAIDs, driven by high rates of self-medication, and underscores the critical role of pharmaceutical care interventions in mitigating these dangers and promoting rational drug use.

Pain is a universal human experience, and for centuries, people have sought relief in substances that calm inflammation and lower fever. Among the most common tools for this job are a class of medicines known as non-steroidal anti-inflammatory drugs, or NSAIDs. You likely know them by names like ibuprofen or naproxen. These drugs work by blocking specific enzymes in the body that produce chemicals responsible for swelling and pain signals. Because they are effective and available without a prescription in many places, they have become a staple in medicine cabinets worldwide. However, this easy access has created a hidden problem: many people use these drugs without understanding the risks, treating them as harmless remedies rather than powerful medicines that can damage the body if used incorrectly.
This reality forms the backdrop for a comprehensive review conducted by researchers from Brazil, who set out to understand the true cost of this widespread, unmonitored use. The team, led by Sebastião Salazar Jansem Filho and colleagues, gathered existing scientific studies to map out exactly what happens when NSAIDs are taken without proper guidance. They focused on three main questions: how often people are using these drugs on their own, what specific damage this causes to different organs, and how trained pharmacists can step in to stop the harm before it starts. Their work is not a new experiment but a careful synthesis of dozens of studies already published, allowing them to see patterns that individual studies might miss.
The researchers found that the habit of self-medicating with NSAIDs is far more common than many realize. In their analysis of various populations, they discovered that nearly 90 percent of adults in some groups had used these drugs without a doctor's order. The numbers were even more striking in specific groups; among people who exercise regularly, nearly two-thirds used NSAIDs to push through muscle pain, while in a survey of mothers managing fever in children, a staggering 87 percent were administering the medication incorrectly. This behavior is driven by a widespread belief that because these drugs are sold over the counter, they are entirely safe. The review suggests this belief is dangerous, as it leads people to take doses that are too high, use the drugs for too long, or combine them with other medications in ways that create severe health risks.
When these drugs are used without limits, they can attack multiple systems in the body simultaneously. The researchers detailed how the stomach lining, which relies on certain natural chemicals to protect itself, can become eroded, leading to bleeding ulcers. The kidneys, which filter waste from the blood, can suddenly fail because the drugs reduce blood flow to them, a risk that skyrockets if the patient is also taking blood pressure medication. The heart and blood vessels face their own threats; the review highlighted that certain NSAIDs can upset the balance of chemicals that keep blood from clotting too easily, significantly increasing the chance of heart attacks and strokes. Even the liver can suffer unpredictable damage, and for people with asthma, these drugs can trigger severe breathing attacks. The study made it clear that no single NSAID is free from these dangers, though some carry higher risks for the heart while others are more likely to hurt the stomach.
To combat this silent crisis, the authors point to a specific solution: the active role of the pharmacist. In their view, the person behind the counter is not just a seller of medicine but a critical safety gatekeeper. The review outlines a strategy where pharmacists screen customers for hidden risks, such as a history of ulcers or heart disease, and strictly limit how long a person can take these drugs on their own. They recommend that self-medication should never last more than three to five days. If pain persists beyond that short window, the pharmacist should insist the person see a doctor. By following this approach, which includes checking for dangerous interactions with other drugs and educating patients on the correct doses, the healthcare system can prevent many of the severe injuries and hospitalizations currently caused by the careless use of these common medicines.
The final message of the review is that while NSAIDs remain valuable tools for managing pain, their power demands respect. The authors conclude that the current pattern of unrestricted use is a public health challenge that requires a shift in behavior. It is not enough to simply have the drugs available; they must be used with knowledge and supervision. By empowering pharmacists to guide patients and by educating the public that "over the counter" does not mean "without risk," society can ensure that these medicines provide relief without causing the very harm they are meant to prevent.
