As the term is used in NRS 453.385, 639.2353 and 639.2801 and NAC 453.410, the Board interprets "directions for use" to require a prescription or label to specify the dosage, frequency and manner in which the prescribed controlled substance is to be taken or applied, unless the dosage, frequency and manner in which the prescribed controlled substance is to be taken or applied are specifically described on or in the manufacturer's individual packages or containers for the prescribed controlled substance. Use of the phrase "take as directed" or any phrase of similar import does not satisfy the requirements set forth in this section.
