Which specific information must be included in both oral and written prescriptions according to Massachusetts law?

In Massachusetts, the law mandates that the date of prescription issuance must be included in both oral and written prescriptions. This requirement is crucial because it helps to establish the timeline for the medication's validity and ensures that the prescription is filled within an appropriate timeframe. Including the issuance date aids pharmacists in verifying the prescription's legality and safety, particularly in monitoring for potential drug interactions or therapeutic duplications that could arise if a prescription is filled too late or long after it was originally issued.

The other options, while they may contain relevant information in a broader context of prescribing or billing, do not have the same legal necessity when it comes to basic prescription requirements in Massachusetts. For instance, a prescriber's zip code, patient insurance information, or office number may be useful for administrative purposes, but they are not mandatory elements that must be present in every prescription as per Massachusetts law.
