(1) An authorized prescriber may not sell, give to, or prescribe for any person any opium, morphine, alkaloid-cocaine, alpha or beta eucaine, codeine, heroin, or any derivative, mixture, or preparation of any of them, except to a patient believed in good faith to require opium, morphine, alkaloid-cocaine, alpha or beta eucaine, codeine, heroin, or any derivative, mixture, or preparation of the enumerated substances for medical use and in quantities proportioned to the needs of the patient.

(2) A prescription must be written so that the prescription can be compounded by any registered pharmacist. The coding of any prescription is a violation of this section.

(3) A prescription marked “non repetatur”, “non rep”, or “N.R.” cannot be refilled. A prescription marked to be refilled may be filled by any registered pharmacist the number of times marked on the prescription. A prescription not bearing any refill instructions may not be refilled without first obtaining permission from the prescriber. A prescription may not be refilled for more than 1 year from the date the prescription was originally written. A Schedule II prescription may not be refilled.
