Rising prescription drug costs cause consumers to limit use

One thing I've been critical of in recent years has been the incredible costs of prescription drugs. The profit margins on many blockbuster drugs is so high it makes the oil industry look timid.

In fact, a new group of studies that looked t 20 years of former studies suggested that the huge costs of many prescription drugs causes many patients to either cut back or stop taking drugs altogether. This, then, puts the patient's health at risk (naturally).

Specific examples cited were higher co-payments, monthly limits and benefit caps -- all of which were believed to have an effect on the rates of drug use. I'm sure that the pharmaceutical companies really do not want to have customers no longer taking their products -- so perhaps price changes are in order at some point for many of their products?
