Nurofen Express is set to benefit from a £4 million promotional campaign. The advertising push, which started in February, will run until August and highlights the real causes of headaches. The campaign is running across all media, including traditional formats like TV, print and advertising on trains and the tube, as well as innovative media channels such as a video playing across the London underground to grab the attention of commuters. It focuses on informing customers that the real cause of tension headaches is the contraction of muscles in the head and neck.
