I was speaking from years of experience. What happens is that at some point our pharmacist lets us know that the coming month's supply would be declined, but a month's supply would be sent and that I should see my doc, yadda, yadda, yadda. It may be an insurance thing, I'm not sure on that point. I noticed at least a couple of DU-Denizens suggesting that the OP's experience might be her insurance.
I can speak from experience on this.
The bottom 5 vertebrae in my back were blown out and I had surgery some years back. I controlled the pain for years with advil, and that lead to a bleeding stomach eventually, so I can no longer take anything anti-inflammatory in nature because of it. Because of that, I went through a couple of years of trying one prescription after another, all of them made me sick until we tried vicoden... so that's what I landed on and take for pain now. I average only needing the things maybe a combined total of a couple months a year, usually less (I'm telling all this crap for a reason)...
So now what happens is I cannot just get a 1 month order from the doc and get it filled... then use them as needed throughout the year when I mess it all up. I have to go in, pay 250 bucks for a visit, exam, and piss test (for some reason plus that's an added 100 bucks), get the script written that is send to pharmacy. They and the insurance will refuse to fill it for more than 7 days worth because its a "new controlled substance script". I have to go pick that up, the wait a week, then call the doc to get ANOTHER one send to fill the remaining 3 weeks worth. And this isn't even counting the piss tests, and even signing contracts and random UA's whenever they call (so far they've never done that to me). All of that for someone who tries his damnedest to avoid the crap, but still need it on occasion so I can function and get out of bed in the morning during a rough patch of pain.
The intervention is from law, pharmacies, and insurance companies all tossing their own extra policies into the mix and it makes it a very expensive nightmare to get something so simple. Someone else mentioned it somewhere, but I could probably drive into the city and just buy the crap from the back market with less hassle and expense. Of course I don't do that sort of BS, so in order to remain a law-abiding person, I have to jump through these flaming hoops of bullsh**. And it is also important to note, this only works because I've had the same doc for 25 years and he 100% trusts me knowing I hate taking this sh** and keep it tightly controlled. Most people probably can't get a doctor to work with them like this and they are jsut left to suffer through it and go on disability. It's a total crock at this point.
