Only a registered individual practitioner may issue a prescription for a Schedule II, III, IV and V controlled dangerous substance. As authorized by Title 63 Okl.St.Ann. § 2-309(A)(1), an individual practitioner, an authorized employee of the practitioner, or an authorized employee of the facility at which the practitioner works may communicate by telephone an oral prescription for any controlled dangerous substance in Schedules II being prescribed by the individual practitioner. It remains the responsibility of the practitioner to guard against the diversion of CDS by employees authorized by him/her to call in such prescriptions.
