What is the maximum supply duration for Schedule II and III controlled substances that can be filled upon a single prescription in Massachusetts?

In Massachusetts, the maximum supply duration for Schedule II controlled substances that can be filled upon a single prescription is 30 days. For Schedule III controlled substances, the law also limits the filling of a prescription to a maximum of 30 days' supply. This regulation ensures appropriate use and controls the likelihood of misuse or diversion associated with these types of medications.

By setting the limit at 30 days, the state seeks to maintain oversight and allows for more frequent evaluation of the patient's need for the medication, which contributes to safer prescribing practices. The need for a new prescription after 30 days encourages regular follow-ups between healthcare providers and patients to assess ongoing treatment efficacy and necessity.
