NSAID’s are pain relievers such as aspirin, ibuprofen, naproxen, sodium, meloxicam and diclofenac. Most are non-prescriptive and over the counter. These are popular treatments for muscle aches and pains or arthritis. They relieve pain, they decrease inflammation, they prevent blood clots and they reduce fevers. They work by blocking the actions of cyclooxygenase or COX enzyme. There are two forms of COX enzymes. COX2 enzymes are produced with injury or inflammation, which NSAIDs counteract. COX1 enzymes protect the stomach lining from acids and digestive juices and helps the kidneys function properly. This is why the side effects of NSAIDs may include nausea, upset stomach, ulcers, and improper kidney function.
