What are NSAIDs primarily used to reduce?

NSAIDs, or nonsteroidal anti-inflammatory drugs, are primarily used to reduce fever and inflammation. They work by inhibiting the production of certain chemicals in the body known as prostaglandins, which play a key role in promoting inflammation, pain, and fever. By reducing the levels of prostaglandins, NSAIDs effectively help alleviate symptoms such as swelling, tenderness, pain, and elevated body temperature.

This mechanism makes them particularly useful for conditions where inflammation is a primary concern, such as arthritis, muscle injuries, or various other inflammatory disorders. Their ability to lower fevers also makes them valuable in treating infections or illnesses that cause elevated body temperature.

In contrast, the other options do not accurately represent the primary uses of NSAIDs. While they may have some effect on headaches or related symptoms indirectly through pain relief, their primary indication revolves around reducing inflammation and fever. Therefore, focusing on their main therapeutic roles helps clarify their uses in clinical practice.
