Isn't it a bit weird that , for example, an electric toothbrush comes with a manual in innumerable languages, yet a patient information leaflet for medication comes in just one?

That is, in the Netherlands it comes with only one language.
Is this the same for the country you live in?
If yes, isn’t that ‘the world turned upside down’; would it not be more important to inform all people from different origins (with their own native tongues) about possible side effects drugs can have, then for them to be informed about the working of said electric toothbrush?
Surely, the size of the print can’t be the problem; we already need magnifiers to read them PILs…
