The ASA received 12 complaints about a TV ad for Nurofen Express in February and began its investigation in March.
According to the regulatory body, the complaints challenged whether the ad misleads by implying the product directly targets muscles in the head. People have also questioned whether the claim "gives you faster headache relief than standard paracetamol or ibuprofen" is misleading.
A spokesman for the ASA said: "This is a complex case and our investigation is ongoing. The advertiser is providing evidence to substantiate its claims, we’re carefully assessing that and we’ll publish our findings in due course."
News of the investigation follows .
The court held that Nurofen’s specific pain products (for back pain, period pain etc) were identical despite claiming to do different things on the packaging. Australia’s Competition & Consumer Commission has given RB three months to remove the products from sale in the country. A separate court hearing will be held to decide if RB must pay a fine.
The ASA spokesman said the Australian court’s decision falls outside its jurisdiction and is a legal matter, not a regulatory one. He also reiterated that packaging information is not within the ASA's remit.
