The PBM's and the mail order deals are pretty much one and the same. The mail order is the worst area for drug switching. However, the present ajudication process has markers on certain drugs that either won't go through or require extra calls etc on the pharmacists part. Ask a practicing pharmacist they will explain it. The whole formulary deal is nothing more than the PBM's making money by pushing higher rebated drugs. The savings to the employer via mail order is now being questioned. The part I really dislike is the therapeutic substitutions where they can change the type of drug used. For example, allegra was the drug of choice for the local HMO. If a doctor wrote a script for claritin it would be a much higher copay or require a bunch of red tape on the doctor and/or pharmacist's part. So if people got headaches with allegra, which can happen, they had a tough time getting their claritin. Its all a financial game. Patient care is secondary to the PBM's profit. My opinion. Next time the PBM pharmacists are in you should drill them on rebates and drug switching. As far as mail order I question if the generics they use. For example, When I take V-cillinK 500 I can smell it in my urine. Just like you should. I have never taken a generic that did the same thing. Ever smell the brand name keflex and then smell the generic? The generic smells like rotton eggs. Why? Who regulates the PBM's? Check into it. They are not regulated as much as you think. Not as much as a regular pharmacy. The jobs are about production checking or drug switching.
