Pharmaceuticals banned by industrialized countries' health authorities as deadly, dangerous or ineffective are routinely marketed in the Third World. Dipyrone, which can cause fatal blood damage, is freely available without prescription in many countries in Latin America under 100 different brand names. In the Pacific and Southeast Asia it is available under about 30 brand names. Deaths from dipyrone may be in the range of 5 persons per 1000 users, with national usage levels giving a probability of one to several thousands of mortalities per country. On a world-wide scale the deaths from this one drug marketed perhaps in over 60 countries may be estimated as already having exceeded 10,000.
