Pharmacy rules in Massachusetts
Massachusetts requires generic substitution unless the prescriber writes no substitution, has required all prescriptions to be electronic since 2020, limits first opioid prescriptions to seven days, reports gabapentin to its monitoring program, and has recently moved to cap insulin cost-sharing.
Massachusetts Board of Registration in Pharmacy: licence lookup and complaintsGeneric substitution
Massachusetts requires a pharmacist to substitute a less expensive generic equivalent unless the prescriber has written “no substitution” on the prescription or indicated it electronically. The pharmacist must tell the patient about the substitution. A patient may ask for the brand and pay for it. The state publishes its own formulary of interchangeable drugs based on the FDA’s ratings, and interchangeable biological products follow similar rules with notice to the prescriber.
Moving a prescription between pharmacies
Massachusetts has required prescriptions, controlled and non-controlled, to be transmitted electronically since 2020, with exceptions for situations such as veterinary prescriptions and prescriber waivers, so most patients no longer carry paper. Non-controlled prescriptions can be transferred between pharmacies without a state limit. Refills are valid for a year from the date written. A pharmacist may dispense up to a ninety-day supply of a non-controlled maintenance medicine when the prescription allows.
Controlled substances
First opioid prescriptions for acute pain are limited to seven days in Massachusetts, and prescribers must check the Massachusetts Prescription Awareness Tool (MassPAT) before prescribing most controlled substances. Gabapentin is not scheduled but is reported to MassPAT. Schedule II prescriptions cannot be refilled; Schedule III to V may be refilled up to five times within six months. A Schedule II prescription may be transferred electronically once under the federal rule.
What a pharmacist can prescribe or furnish
Massachusetts pharmacists may dispense naloxone under a statewide standing order, administer vaccines, and manage drug therapy under collaborative agreements. Massachusetts has enacted a law allowing pharmacists to prescribe hormonal contraception; check the board for when and where it is in effect. Services vary by pharmacy.
Insulin and cost-sharing caps
Massachusetts has recently enacted a cap on insulin cost-sharing for state-regulated health plans at a low fixed amount per thirty-day supply; check the current status and start date with the state. It does not apply to self-funded employer plans or to patients paying cash. The federal Medicare Part D cap applies to Part D plans. For cash-paying patients no cap applies.
Veterinary prescriptions
A veterinarian’s prescription for a human drug is filled by a Massachusetts pharmacy under the same substitution rules; veterinary prescriptions are exempt from the electronic-prescribing requirement, so paper prescriptions from vets are normal. Veterinary gabapentin prescriptions are reported to MassPAT like any other. The Board of Registration in Veterinary Medicine requires a veterinarian-client-patient relationship before prescribing, and veterinarians provide prescriptions on request.
