The allergy medicine allegra went OTC this month. Before it went OTC it was $30-$50 copay with insurance for a 30 day supply. This month it went OTC and you can get a 90 day supply for $35.
Ummm ... based on my experience, either your health insurance or your doctor is deficient. My experience is roughly the opposite of yours; this OTC change is substantially
increasing my cost. I was paying a $5 monthly co-pay for an "Allegra" prescription. There is a difference, however. When the patents on Allegra expired, my doctor switched me to the generic, fexofenadine. Doctors who continued to prescribe the expensive branded version weren't doing their patients any favors.
I'm also curious where you're finding a 90 day supply of OTC Allegra for only $35. I'm finding it more in the $50 to $60 range.
Allowing insurance to be involved in every healthcare transaction has warped the market.
Probably true, but I don't think your example is a good one. It's more an example of the way intellectual property laws protect innovation at a cost to consumers. I suspect it's also an example of why big pharma spends more on marketing than it does on R&D. I'm sure many doctors continued to prescribe the branded version and consumers continued to demand it because pharma marketing trumped sound financial and medical judgment.
Markets work when you let them.
Maybe, though I suspect it depends on your definition of "work." I recognize it's a dearly-held talking point of the right, but it seems to me to be based more on speculation and wishful thinking than objective evidence. What most pseudo-free markets around the world seem to have done is allow a very small number of companies to become so mammoth they eventually control their markets, with the most competitive markets being those with the tightest controls on corporations and wealth.
The retort is traditionally something about these markets not really being free and that is the government that enables such business oligarchies. I have yet to see any real world counter-examples, however. Instead it's just empty dogma earnestly and tirelessly repeated to other true believers until they all just "know" it must be true. In short, it's a great tale but I'd like to see actual data.
