Aspirin, a type of salicylate and nonsteroidal anti-inflammatory drug (NSAID), is used to alleviate mild to moderate pain caused by conditions such as toothaches, muscle aches, headaches, and the common cold, while also reducing fever. It can also alleviate pain and inflammation caused by arthritis. By blocking certain natural substances in the body, aspirin reduces swelling and pain. It is important to seek medical advice before giving aspirin to a child under 12 years of age. In some cases, doctors may recommend low-dose aspirin to prevent blood clots, which can help reduce the risk of stroke and heart attack. After certain procedures like bypass surgery, carotid endarterectomy, and coronary stent, doctors may also prescribe low-dose aspirin as a "blood thinner" to prevent blood clots.
