That's along the lines of what I'm thinking.
My experience has been that the insurance will only allow 30 days at a time, and you cannot get a refill until close to 30 days is up - you might be allowed to refill 3-4 days early, but not over a week early.
I *think* what Carrie is trying to say is that the pharmacist recorded it as a 30 day supply, but put in only a 15 day supply: "when I went to get my new prescription was told the pharmacist put 30 day supply on my prior prescription." Therefore, because Carrie only had a 15 day supply, but the pharmacist entered it as a 30 day supply, Carrie is not going to be authorized for a refill right now.
It does not have to be an opiate prescription for this to happen. It could be a clerical error, a mathematical error, or it could be even a pharmacist wrongly assuming there was an error in the prescription.
An inexperienced pharmacist might erroneously assume the doctor made a clerical error and "correct it" - of course, the correct thing to do if an error is suspected is to contact the doctor and verify the prescription was meant to be as written. For example, a prophylaxic dosage of warfarin (rat poison) is 2 mg - 10 mg / day, with the blood tested regularly since too high a dosage over a prolonged time can result in internal bleeding and death. However, a family member was prescribed 25 mg-30 mg/ day (warfarin-resistant). People with warfarin-resistance need much higher doses of the medication, doses that would be fatal for most people, and so it is understandable that a pharmacist might look more than twice when filling a prescription. But I would think that, ethically, pharmacists are bound to honor what's written on the prescriptions, and if they think the doctor has made a mistake that would endanger the patient's life, they should contact the doctor before filling the prescription to determine if a correction is necessary.
