Iowa Admin. Code r. 657-21.12
A pharmacist may dispense Schedule II controlled substances pursuant to an electronic transmission to the pharmacy of an electronically prepared prescription if both the prescriber's electronic prescription application and the pharmacy prescription application have been certified to comply with DEA requirements for electronic prescribing of controlled substances. Records of electronically prepared and transmitted prescriptions shall be maintained electronically. A pharmacist may dispense Schedule II controlled substances pursuant to facsimile transmission to the pharmacy of a written, signed prescription from the prescribing practitioner or the practitioner's agent provided that the original written, signed prescription is received by the pharmacist prior to the actual dispensing of the controlled substance. An emergency authorization transmitted to the pharmacy by the practitioner's agent shall include the first and last names and title of the individual who transmitted the prescription. The means of transmission shall ensure that prescription information is not obscured or rendered illegible due to security features of the paper utilized by the prescriber to prepare a written prescription. The original prescription shall be verified against the transmission at the time the substance is actually dispensed, shall be properly annotated, and shall be retained with the electronic transmission for filing.
