Personally, I think it is misleading to say that a product is designed to deal with specific types of pain - back pain, migraine, stress headache - if the same tablet with the same constituents is being sold in each case.
The reason an investigation is being launched in the UK is presumably to discover whether products are being marketed in a misleading way and/or, perhaps more importantly, whether any differences in price can be justified.
thatbags I sense you are being rather sarcastic thatbags. I am sure you are perfectly capable of searching the publications I mentioned and finding out for yourself. I have no personal knowledge of the product since I only take paracetamol. Aspirin, codeine and ibuprofen make me feel nauseous. I posted some weeks ago about a TV programme highlighting some concerns about the labelling of painkillers. I then saw a recent report relating to the same product in Australia. Presumably the UK authorities feel that, in the light of that case, there are grounds to investigate the product here.
I don't understand why it is thought acceptable to refer to people as being "lazy" or "dim" when it may be quite possible that some of them do not have knowledge of marketing techniques or know how to decode information with which they are not familiar. People are all different - some have mild or moderate learning disabilities, some have, for a variety of reasons, had a poor education and now have low levels of literacy, some may be elderly and find it harder to interpret information. I don't think it's right to say "I've got the knowledge and ability to know when I'm being hoodwinked - tough luck if you haven't".
