At the same time, good luck getting a doctor to suggest a $5 jar of salve over a $200 tube of prescription salve, even if it's the very same stuff.
That's a real problem. Many doctors default to the new name brand X rather than the tried and true generic Y even when just the co-pay for X will cost more than Y. Often, X will be no better than Y for the majority of patients. As a result, some people pay WAY too much and some end up not getting X or Y. A tiny handful avoid mild itching that could have been fixed by switching them to X if they cared to.
