What is the primary use of aspirin?

Aspirin is primarily used as a painkiller and to lower fever due to its properties as a non-steroidal anti-inflammatory drug (NSAID). It works by inhibiting the production of certain chemicals in the body called prostaglandins, which play a key role in signaling pain and inflammation. By blocking these chemicals, aspirin effectively alleviates pain and reduces fever.

The use of aspirin to treat infections is not accurate, as it does not have antibiotic properties and does not kill pathogens. While it may provide relief from pain caused by an infection, it does not treat the underlying cause. Aspirin also does not increase blood pressure; rather, its effects can vary regarding cardiovascular health. Lastly, although aspirin may have some indirect effects on mood due to its influence on inflammation, it is not classified as a treatment for enhancing mood or reducing anxiety. Its principal functions remain firmly within pain relief and fever reduction.
