It is possible that those specific pills have another affect and are there for being prescribed - all sorts of drugs have multiple affects, for example Viagra was invented for a whole other purpose and I think also treats altitude sickness. There might be a legit explanation (though TBH I doubt it and I would have thought it would be volunteered at the outset)
