For years, Clark has told you how your prescription info has been sold into the marketplace. This info has included your medication, dosage, address, Social Security number and more.

Doctors have historically been monitored by pharmaceutical companies based on this info. If the docs were writing too many generic prescriptions, they would get visits from pharmaceutical reps to convince them to write name-brand scripts.

But now, buried in the zillions of pages of the federal stimulus law is a new provision making it illegal for your info to be trafficked in this way. This is the first-time ever that consumers are getting some protections.

What does it mean for you? Pharmacy benefits managers (PBMs) through your employer health coverage will no longer be allowed to sell your info.

Several of the nation's big drugstore chains that were involved in this data selling will be impacted too. A CVS spokeswoman told The New York Times that, "In very limited circumstances, we exchange aggregated, de-identified data with third parties to assist the health care community in understanding patient use of prescription medications with the goal of achieving better health outcomes."

In addition, you won't be receiving any more mailers from drugstore chains when it's time to refill a prescription. This now constitutes a privacy breach.
