Question of the Day November 1 2015 Should prescription drug information be data-mined for a medical office's and a pharmacies patient population to see how many patients are being prescribed the exact same compounded prescription since 503A addresses the medical needs of individual patients that cannot use FDA-approved products? Why or why not? How probable or improbable is it that a medical office's entire patient population would be intolerant to FDA-approved drugs and need the exact same dose and formula of a compounded drug?
