Eczema medication costs a few cents to produce, you can get it for a few bucks in almost every country, but the patents in the US and the weakened regulatory system due to corporate pharmaceutical lobbying means that the patent holders can charge whatever they want and until healthcare reform occurs or unless a specific law is passed, like with insulin, US shoppers will keep paying literally any price the patent holders and their subsidiaries pull from the top of their heads and write down on your bill.
