IIRC, there are quite a few episodes of Voyager showing the hypospray being loaded/reloaded with a cartridge. It’s unclear how many doses are contained in the cartridge, but typically more than one. I would think that for most treatments the Sickbay replicator just produces a ready-to-use batch of cartridges, whereas for more specialised medication the EMH has to actually make it up manually.
They can be configured for different medications on a single cartridge though, it seems like, so it must not be just medicine, but some kind of solution of components that the case can mix
