Introduction

Nurofen is a non-steroidal anti-inflammatory drug (NSAID) used to treat fever, pain, stiffness and swelling caused by inflammation. It is sold over the counter and is commonly used to reduce aches and pains due to dental work, minor injuries, menstrual cramps, headaches, colds, and other minor ailments.

Uses For Nurofen

Nurofen is commonly used to treat pain, fever and inflammation, although it can have other uses as well.
