The pharmacy quality assurance commission may make such rules for the enforcement of this chapter as are deemed necessary or advisable. The commission shall identify, by rule-making pursuant to chapter
34.05 RCW, those drugs which may be dispensed only on prescription or are restricted to use by practitioners, only. In so doing the commission shall consider the toxicity or other potentiality for harmful effect of the drug, the method of its use, and any collateral safeguards necessary to its use. The commission shall classify a drug as a legend drug where these considerations indicate the drug is not safe for use except under the supervision of a practitioner.
In identifying legend drugs the commission may incorporate in its rules lists of drugs contained in commercial pharmaceutical publications by making specific reference to each such list and the date and edition of the commercial publication containing it. Any such lists so incorporated shall be available for public inspection at the headquarters of the department of health and shall be available on request from the department of health upon payment of a reasonable fee to be set by the department.
