Common Types and Uses of Over-the-Counter Anti-Inflammatory Medications
Over-the-counter (OTC) anti-inflammatory medications, primarily non-steroidal anti-inflammatory drugs (NSAIDs), are widely used to relieve pain, reduce inflammation, and lower fever. Common examples include ibuprofen, naproxen, and mefenamic acid. These medications are frequently used for headaches, backaches, body aches, and other minor pains, and are available in various forms such as oral tablets, topical creams, and more 1456.
Mechanism of Action of OTC NSAIDs
NSAIDs work by inhibiting cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2, which are involved in the production of prostaglandins—chemicals that promote inflammation, pain, and fever. By blocking these enzymes, NSAIDs help reduce these symptoms 457. Recent research also shows that some NSAIDs activate the NRF2 pathway, which provides additional anti-inflammatory effects beyond COX inhibition .
Patterns of Use and Public Awareness
OTC NSAIDs are commonly used by a significant portion of the general population, with studies showing that nearly one-third of adults report using these medications. Even among individuals at high risk for adverse effects, such as those with cardiovascular disease, a notable percentage still use OTC NSAIDs . Most people use these drugs as needed, but some take them for longer periods or at higher doses than recommended 13.
Despite their widespread use, public knowledge about the proper use, potential side effects, and drug interactions of OTC NSAIDs is generally low. Less than 35% of users receive adequate information from healthcare professionals about these risks, and the majority are unaware of possible drug interactions and adverse effects .
Side Effects and Risks of OTC NSAIDs
While OTC NSAIDs are effective for pain and inflammation, they are associated with a range of side effects. Common mild side effects include drowsiness, abdominal pain due to acidity, dizziness, and mild diarrhea . More serious risks include gastrointestinal bleeding, ulcers, kidney problems, heart attack, and stroke, especially with prolonged use or in high-risk individuals 34510.
Efforts to reduce these risks have led to the development of COX-2 selective NSAIDs and prodrug formulations, which aim to minimize gastrointestinal side effects, but some risks remain 410.
Special Considerations for Athletes and Specific Populations
Athletes and those involved in sports medicine frequently use OTC NSAIDs to manage pain and inflammation. Athletic trainers often administer these medications, but there is variability in their knowledge and comfort with their use, highlighting the need for better education in this group .
Environmental Impact of OTC NSAIDs
The widespread use of OTC NSAIDs has also led to their presence in the environment, where they can affect living organisms. These drugs are metabolized in the body and can be further broken down by microorganisms in the environment, but their persistence raises concerns about ecological risks .
Conclusion
OTC anti-inflammatory medications, especially NSAIDs, are widely used for pain and inflammation relief. While effective, they carry risks of side effects and serious health complications, particularly with improper or prolonged use. Public awareness of these risks is low, underscoring the need for better education from healthcare professionals. Additionally, the environmental impact of these drugs is an emerging concern. Responsible use and ongoing efforts to develop safer formulations are essential for minimizing harm.

Profiling, Patterns of Intake and Perceived Side Effects on the Use of Over-The-Counter Non-Steroidal Anti-Inflammatory Drugs
Most respondents use over-the-counter non-steroidal anti-inflammatory drugs to relieve pain, despite potential side effects like drowsiness, sleepiness, and mild diarrhea.
High-risk use of over-the-counter non-steroidal anti-inflammatory drugs: a population-based cross-sectional study.
OTC NSAIDs are used by nearly one-third of the general population and one in eight high-risk patients, highlighting the need for continued efforts to inform patients of the risks of these drugs.
