No, you need a prescription in the US. And that prescription is withheld by sleep specialist “doctors” until you do an expensive and unnecessary sleep study. These doctors serve no useful role other than telling you really obvious things, but you are forced into multiple appointments with them just for the prescriptions. Going through insurance then can require at least one more follow up appointment, but sometimes more depending on your plan. Some of them require multiple appointments where the doctor confirms your usage.
