What type of drugs may NOT be filled for more than a thirty-day supply upon a single prescription in Massachusetts?

In Massachusetts, prescriptions for certain types of controlled substances must adhere to specific limits regarding the quantity that can be dispensed at one time. Schedule II and III controlled substances are particularly regulated due to their potential for abuse and dependence. According to Massachusetts state regulations, a pharmacist cannot fill a prescription for a Schedule II or Schedule III substance for more than a thirty-day supply in one dispensing. This limit is in place to help manage the risks associated with these medications and to promote safe prescribing practices.

On the other hand, over-the-counter medications, non-controlled substances, and Schedule IV controlled substances do not share the same restrictions. Non-controlled medications can typically be filled in larger quantities, while Schedule IV controlled substances, although still controlled, have a lesser potential for abuse and can also be prescribed for a longer duration. This regulation aims to enhance patient safety and provide a structured approach to managing prescriptions for medications that carry higher risks.
