Final answer:
The answer depends on local laws and regulations; some areas may allow emergency refills, while others require authorization before additional dosages can be dispensed.
Step-by-step explanation:
The amount of additional days of dosages that a pharmacist can dispense to a patient when proper authorization cannot be obtained during the first 72-hour period varies depending on the regulations of the specific country or region. While some regions may allow emergency refills for a set amount of days in the absence of authorization, others may have stricter regulations that do not permit additional dispensing without authorization. It is crucial to consult the local pharmacy laws and regulations to determine the exact number of additional days that are permissible under such circumstances. Furthermore, it may be dependent on the type of medication and the circumstances of the prescription.
