Simply put, what is this medicine?

This is actually a combination of two types of medication.

1. Acetaminophen: This name may sound unfamiliar to you, but it is what we all know as paracetamol . It works by reducing pain and fever in our bodies.

2. Caffeine: This is a stimulant found in things like tea and coffee. Caffeine is added to this medicine for two reasons. One is that caffeine increases the pain-relieving properties of paracetamol a little more. Secondly, caffeine gives our brain a little boost and helps reduce the sluggishness caused by pain.

Simply put, the combination of these two quickly relieves simple pains like headaches and muscle aches.
