False, there are three (western?) countries that allow it: USA, New Zealand, and Brazil [1]. Here in NZ, there are not very many ads on TV for prescription mediation. "Ask your doctor" is a common phrase, but I get the impression that the large majority of advertised drugs are non-prescription. (But I watch little TV and I certainly avoid watching TV ads)
