The DEA changed the rule in 2007, here it is and the link:
Issuance of Multiple Prescriptions for Schedule II Controlled Substances
The DEA has revised its regulations regarding the issuance of multiple prescriptions for schedule II controlled substances. Under the new regulation, which became effective December 19, 2007, an individual practitioner may issue multiple prescriptions authorizing the patient to receive a total of up to a 90-day supply of a schedule II controlled substance provided the following conditions are met:
Each prescription must be issued on a separate prescription blank.
Each separate prescription must be issued for a legitimate medical purpose by an individual practitioner acting in the usual course of professional practice.
The individual practitioner must provide written instructions on each prescription (other than the first prescription, if the prescribing practitioner intends for that prescription to be filled immediately) indicating the earliest date on which a pharmacy may fill each prescription.
The individual practitioner concludes that providing the patient with multiple prescriptions in this manner does not create an undue risk of diversion or abuse.
The issuance of multiple prescriptions is permissible under applicable state laws.
The individual practitioner complies fully with all other applicable requirements under the CSA and C.F.R., as well as any additional requirements under state law.
It should be noted that the implementation of this change in the regulation should not be construed as encouraging individual practitioners to issue multiple prescriptions or to see their patients only once every 90 days when prescribing schedule II controlled substances. Rather, individual practitioners must determine on their own, based on sound medical judgment, and in accordance with established medical standards, whether it is appropriate to issue multiple prescriptions and how often to see their patients when doing so.
