657—10.21 (124,126,155A) Prescription requirements. All prescriptions for controlled substances shall be dated as of, and manually signed on, the day issued. Controlled substances prescriptions shall be valid for six months following date of issue.
	 10.21(1) Form of prescription. All prescriptions shall bear the full name and address of the patient; the drug name, strength, dosage form, quantity prescribed, and directions for use; and the name, address, and DEA registration number of the prescriber. All prescriptions issued by individual prescribers shall include the legibly preprinted, typed, or hand-printed name of the prescriber as well as the prescriber’s signature. When an oral order is not permitted, prescriptions shall be written with ink, indelible pencil, or typed print and shall be manually signed by the prescriber. A secretary or agent may prepare a prescription for the signature of the prescriber but the prescribing practitioner is responsible for the accuracy, completeness, and validity of the prescription. A corresponding liability rests upon the pharmacist who fills a prescription not prepared in the form prescribed by this rule.
	 10.21(2) Verification by pharmacist. The pharmacist shall verify the authenticity of the prescription with the individual prescriber in each case when a prescription for a Schedule II controlled substance is presented for filling and neither the prescribing individual practitioner issuing the prescription nor the patient or patient’s agent is known to the pharmacist. The pharmacist is required to record the manner by which the prescription was verified and include the pharmacist’s name or unique identifier.
	 10.21(3) Intern, resident, foreign physician. An intern, resident, or foreign physician exempt from registration pursuant to subrule 10.6(5) shall include on all prescriptions issued the hospital’s registration number and the special internal code number assigned by the hospital in lieu of the prescriber’s registration number required by this rule. Each prescription shall include the stamped or printed name of the intern, resident, or foreign physician as well as the prescriber’s signature.
	 10.21(4) Valid prescriber/patient relationship. Once the prescriber/patient relationship is broken and the prescriber is no longer available to treat the patient or to oversee the patient’s use of the controlled substance, a prescription shall lose its validity. A prescriber/patient relationship shall be deemed broken when the prescriber dies, retires, or moves out of the local service area or when the prescriber’s authority to prescribe is suspended, revoked, or otherwise modified to exclude authority for the schedule in which the prescribed substance is listed. The pharmacist, upon becoming aware of the situation, shall cancel the prescription and any remaining refills. However, the pharmacist shall exercise prudent judgment based upon individual circumstances to ensure that the patient is able to obtain a sufficient amount of the drug to continue treatment until the patient can reasonably obtain the service of another prescriber and a new prescription can be issued.
	 10.21(5) Schedule II prescriptions. With appropriate verification, a pharmacist may add information provided by the patient or patient’s agent, such as the patient’s address, to a Schedule II controlled substance prescription. A pharmacist shall never change the patient’s name, the controlled substance prescribed except for generic substitution, or the name or signature of the prescriber. After consultation with the prescribing practitioner and documentation of such consultation, a pharmacist may change or add the following information on a Schedule II controlled substance prescription:
	  a.   	 The drug strength;
	  b.   	 The dosage form;
	  c.   	 The drug quantity;
	  d.   	 The directions for use; and
	  e.   	 The date the prescription was issued.
