There is tracking system for schedule one prescriptions such as oxycontin or oxycodone. It is unavailable to pharmacists, but is available to the government, who recently have begun to monitor the prescription practices of those who allegedly "overprescribe", and identify patients who go "doctor shopping" for opiates.
Not to my knowledge. Except that if you go to Rite Aide pharmacy or CVS etc. they have their systems linked and have all this information across the country I believe. But other than that there doesn't seem to be a national system for that. Social security (medicare) may also have the same kind of system as these pharmacys but it would be a limited population as well. We need that as well as your heath issues. Problem is the insurance companies my get ahold of some of this information and use it agaist the patient. That is why they have HIIPA. So one wouldn't be able to have a systmem like that and have it open to anyone to view or for even the insurance companies to view without your permission. There are some drugs people buy that may not be purchased by your insurance because you don't want them to know. Same goes for someone with for example an STD and they don't want their spouse or mother or someone see their information. The privacy issues would have to be intact.
