The following drugs or devices, that are intended for use by man, shall be sold only upon a written prescription of a practitioner licensed by law to prescribe the drug or device, or upon an oral prescription of the licensee that is reduced promptly to writing and filed by the pharmacist, or by refilling the written or oral prescription if the refilling is authorized by the prescriber either in the original prescription or by oral order that is reduced promptly to writing and filed by the pharmacist: (a) A habit forming drug to which Section 111350 applies. (b) A drug or device that, because of its toxicity or other potentiality for harmful effect, or the method of its use, or the collateral measures necessary to its use, is not safe for use except under the supervision of a practitioner licensed by law to administer the drug or device.
