That's a US problem. The prices of all medicines in for example Denmark are publicly available. The medicine is purchased by a single entity(and there are proposals to combine the entities within the Nordic countries to form a single large purchaser), so to sell medicine in Denmark you'll have to play ball. The prices are therefore quite reasonable. Insulin which is a commonly used example of overpriced medicine in the US is around 40-50 USD in Denmark. That is the brand version from Novo Nordisk.
