Aspirin is a pain reducer available in both prescription and non-prescription forms. It works by stopping the production of natural substances that cause pain, swelling, fever or blood clots. Aspirin is a part of salicylate drug group and is a non-steroidal, anti-inflammatory drug (NSAID). It is sometimes found in combination with other antacids, pain relievers or cold medication.
Non-prescription aspirin is commonly used to lessen mild-to-moderate pain caused by headaches, toothaches, muscle aches, colds, menstrual cramps or arthritis. It is also often used to reduce fever. Additionally, aspirin can be a preventive medicine for a variety of ailments, including heart attacks, some strokes, and blood clots in patients with artificial heart valves.
