Aspirin is a medication commonly used to relieve pain, reduce fever, and decrease inflammation. It belongs to a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs), and it works by blocking the production of certain natural substances in the body that cause pain, fever, and inflammation. Aspirin is often used to treat conditions such as headaches, muscle aches, arthritis, and minor injuries. It is also used in lower doses to reduce the risk of heart attacks and strokes in people at high risk for these conditions.

They are commonly kept in homes, cars, workplaces, and outdoor settings for immediate and easy access during accidents or medical emergencies.

Proper application of a bandage is important to make sure it stays in place and provides effective wound care.

They come in different sizes and shapes to fit different kinds of injuries and are a common item in first aid kits and homes for quick, temporary wound care.
