Does Guam have a designated list of drugs that are not substitutable?

In Guam, there is no designated list of drugs that are explicitly labeled as non-substitutable. This means that pharmacists do not have a legally mandated reference that outlines which prescriptions cannot be substituted for alternative medications. While some states may have similar lists to ensure patient safety and provide guidance regarding medication dispensing, Guam does not implement this system. Therefore, the correct understanding is that there is no formalized list governing non-substitutable drugs in Guam.

The other options suggest varying levels of regulation or lists that do not exist within Guam's legal framework for pharmacy practice.
