Aspirin

Pronounced (as’ pir in)

Why is Aspirin Prescribed?

Prescription aspirin is used to relieve the symptoms of rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, and certain other rheumatologic conditions. Nonprescription aspirin is used to reduce fever and to relieve mild to moderate pain from headaches, arthritis, toothaches, and muscle aches. Nonprescription aspirin is also used to prevent heart attacks in those who have had a heart attack in the past or who have angina (chest pain that occurs when the heart does not get enough oxygen). Nonprescription aspirin is also used to prevent ischemic strokes or mini-strokes in those who have had this type of stroke or mini-stroke in the past.  Aspirin will not prevent hemorrhagic strokes (strokes caused by bleeding in the brain).

How Does Aspirin Work?

Aspirin is in a group of medications called salicylates. It works by stopping the production of certain natural substances that cause fever, pain, swelling, and blood clots.
