How often must prescriptions for implantable infusion pumps, consisting of Schedule I or II controlled substances, be filled?

The regulations regarding the frequency of refills for prescriptions involving Schedule I or II controlled substances are stringent, particularly for specific devices like implantable infusion pumps. In Massachusetts, a prescription for a controlled substance that is used for continuous delivery through an implantable infusion pump is typically governed by the requirement to be filled every 90 days. This is primarily to ensure that patients are monitored adequately while receiving these potent medications, allowing healthcare providers to review the patient's condition and adjust the dosage as necessary.

Refilling these prescriptions on a more frequent basis, such as monthly or every 6 months, does not align with state and federal guidelines aimed at preventing misuse and ensuring safe prescribing practices. The 90-day interval provides a balance between accessibility for patients in managing their pain or other conditions while maintaining oversight by healthcare professionals. Furthermore, this approach helps mitigate the risks associated with potential abuse or diversion of these powerful substances.
