It's definitely a US only problem. There are, for instance, multiple competing competing brands of EpiPen competitors in Europe. In the US the FDA's mandate concerns safety only and private entities can sue it to force it to do its job if they think it isn't. Which makes it easy for big companies to launch lawsuits alleging that their potential competition can't prove that they can produce drugs as safely as the incumbents.
