It IS overly antagonistic. Maybe this stuff is overpriced but I think there is a need in the market. Lots of medication is protected by patents and overpriced. Doctors also gatekeep a lot of basic medications like Viagra. Third world countries are not nearly as uptight about medication, and probably sell Viagra and such as OTC medications. Perhaps the prescription system in the US can detect drug interactions, but for something like that there is probably little benefit to having a doctor in the loop. As for the quality of the medication, that could be debated. But it is quite possibly made at the same factories as the prescription stuff.
