Acetaminophen, also known as Paracetamol, Tylenol, Mapap, or Panadol, is a widely used over-the-counter medication that helps manage pain and reduce fever. It is an active ingredient found in various brand-name products, and it’s considered safe when taken as directed. However, misuse can lead to severe liver damage or other health problems.

What is Acetaminophen?

Acetaminophen is a common medication that you may find in many households. It’s found in many over-the-counter drugs and is often used to alleviate headaches, muscle aches, menstrual periods, mild forms of arthritis, toothaches, backaches, and other types of mild to moderate pain. It can also lower fever. Unlike nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen does not reduce inflammation.

How Does It Work?

The precise mechanism by which acetaminophen works is still not fully understood. It is believed to reduce the production of chemicals called prostaglandins in the brain, which can cause pain and fever.

When you use acetaminophen, it’s essential to follow the instructions on the bottle or consult with a doctor and pharmacist. This medication can be taken orally, usually as a tablet, chewable tablet, or liquid.
