Sometimes controlled substances are reclassified. That is, a Note Q
controlled substance might be reclassified as a Note R controlled substance.
Hence, you should frequently check the classifications of controlled
substances to ensure your knowledge is current.
a. Note Q Substances. Note Q controlled substances are those items
classified as Schedule III, IV, or V in the Controlled Substances Act. Table 3-1 provides
some examples of substances that are classified as Note Q items. It is important for
you to be familiar with the items that are classified as Note Q because later you will
learn that some types of medical personnel are authorized to write for specific Note Q
items. Figure 3-5 is an item from the Federal Supply Catalog. Note that this item is a
Note Q substance.
