That should not be done by pharmacies, that should be done by doctors and lab test results.
I must have been low because my doc put me on 50K of D for a couple of weeks then titrated down but I have not had a subsequent D level test so don't know the efficacy of that regime.
But it sounds like you have an ax to grind against big pharm in general.
And in some cases you are right, the opioid crisis is one big one, and now even Walmart is in trouble for being in there pushing this deadly drug.
My wife almost died from Oxy, she told her pain doc, actually just a PA that the oxy she used, a 6 hour and 12 hour taken apart, was not working so he said double the dose. That resulted in her passing in and out of consciousness and ambulance had to take her to hospital and she was on narcan to counter the huge overdose that stupid PA told her to take.
She literally almost died.
That was very close and now she has stopped taking all that crap and the pain is no worse or no better without those drugs.
We have started the process of switching pain clinics since that near disaster.
Even getting her medical records is a pain in the ass. Two separate agencies have different records and we had to submit a series of forms just to get the release of medical records to the new clinic.
Jeesus, when I was a kid, a doc wanted medical records, he calls up records division and says, give me the records on Mark Mork and they just fax or send them with no questions asked. Now it is a huge problem with overreacting about privacy issues and a big deal when asking for medical records.
