Agreed. That's why I still think it's important that the warfarin be available by prescription only. The practitioner who prescribes the medication would then have the burden of checking to see that the person doing the testing knows what he or she is doing (but, for that matter, the practitioner should be reviewing the patient's values anyway). Of course, the warfarin can be bought from overseas sources and the patient could, conceivably, make major dosing errors. The overseas route makes little sense if the person getting the warfarin has a doctor or can get a prescription (because generic may be even less expensive here, when shipping costs are factored in).
Yes, it's possible that a person can buy a meter at the Acme Tester Store and mismanage the warfarin, but I suspect that if a person was so motivated, he or she would probably be diligent (and intelligent) enough to run the tests. (We should still keep in mind that: a) few of the people buying the meters and supplies are probably doing the testing without reporting to a medical practitioner or anticoagulation specialist and b) that anyone doing his or her own testing will probably be careful because the dosing and testing issues are literally putting their lives into their own hands).
In an earlier post, a person said that you can commit suicide by overdosing on warfarin. It's possible, but not particularly easy, to take a large enough dose for massive internal bleeding -- it may be easier to kill yourself just by stopping taking coumadin and waiting for a clot -- and THIS form of suicide requires NO prescription.
