Aspirin is a commonly used painkiller that has been around for over a century. It is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain， reduce inflammation， and lower fever. Aspirin is one of the most widely used drugs in the world， and it has a long and fascinating history.

Aspirin was first developed in the late 19th century by a German chemist named Felix Hoffman.

The resulting drug was named Aspirin， and it quickly became popular for its pain-relieving properties.

3. How Aspirin Works

Aspirin works by blocking the production of prostaglandins， which are chemicals that cause pain， inflammation， and fever. By inhibiting the production of these chemicals， aspirin can reduce pain and inflammation and lower fever. Aspirin is also an antiplatelet agent， which means that it can prevent blood clots from forming.

Like all drugs， aspirin can cause side effects. The most common side effect is stomach upset， which can lead to nausea， vomiting， and stomach pain. Aspirin can also cause bleeding in the stomach and intestines， which can be serious. People who take aspirin regularly should be monitored for signs of bleeding， such as black stools or blood in the urine.

6. Precautions When Taking Aspirin

Aspirin should not be taken by people who are allergic to salicylates or who have a history of stomach ulcers or bleeding disorders. It should also be used with caution in people who have kidney or liver disease， as well as in pregnant women and children.
