The Nurofen Express advert, shown in early 2015, received 12 UK complaints.The advert in question claims that "most headaches are caused by strained head muscles", and that the painkiller targets these muscles.The ASA received 12 complaints about the advert in February and launched its investigation in March.It said: "Complainants have challenged whether the ad is misleading because it implies that the product directly targets muscles in the head. They’ve also challenged whether the claim ‘gives you faster headache relief than standard paracetamol or ibuprofen’ is misleading."The ASA stressed that it investigates marketing of products, not the product itself."The products are regulated by health regulators such as the Medicines & Healthcare products Regulatory Agency (MHRA)," the ASA added.
