Aspirin is an over-the-counter anti-inflammatory medication used to treat minor aches caused by headaches or beats, muscle aches, and menstrual cramps.
You can also use it to temporarily reduce fever.
Aspirin is a nonsteroidal anti-inflammatory
Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) which is a class of drugs along with ibuprofen and naproxen. They work the same way by reducing the amount of prostaglandins produced by your body.
Prostaglandin is a natural substance produced by most cells in your body. Cells release prostaglandins upon injury. They contribute to inflammation in the body, which leads to various effects, including swelling, fever, and increased sensitivity to pain.
By blocking your body’s production of prostaglandins, NSAIDs such as aspirin can help prevent and relieve these injury symptoms.
