Ann.......once people have it in their mind about drug interactions, injected either by the medical profession or by those bloody fatuous instructions in tablet cartons, then commonsense and individuality goes out of the window.
The treatment of an inflammatory process is a drug which contains anti inflammatory properties and in that, Ibuprofen beats Paracetamol hands down. Also, one is only likely to take ibuprofen for a short period of time, say 3 -5 days at most and in my opinion the benefits of such treatment far outweigh the obscure chance of drug interaction.
