Pharmacy rules in Michigan
Michigan allows generic substitution unless the prescriber writes dispense as written, has required almost all prescriptions to be electronic since 2021, is one of the few states that schedules gabapentin as a controlled substance, and limits first opioid prescriptions for acute pain.
Michigan Board of Pharmacy (Department of Licensing and Regulatory Affairs): licence lookup and complaintsGeneric substitution
A Michigan pharmacist may substitute a generic equivalent unless the prescriber has written “dispense as written” or the equivalent on the prescription or indicated it electronically. The pharmacist must tell the patient about the substitution and the substituted product must cost the patient less. A patient may ask for the brand and pay for it. Substitution follows the FDA’s therapeutic equivalence list, and interchangeable biological products follow similar rules.
Moving a prescription between pharmacies
Michigan has required prescriptions, controlled and non-controlled, to be transmitted electronically since 2021, with exceptions for situations such as veterinary prescriptions, emergencies 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
Michigan schedules gabapentin as a Schedule V controlled substance, which means gabapentin prescriptions carry the refill, transfer and reporting rules of a controlled drug, including reporting to the Michigan Automated Prescription System (MAPS), which prescribers must check before prescribing most controlled substances. First opioid prescriptions for acute pain are limited to seven days. 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
Michigan pharmacists may dispense naloxone under a statewide standing order, administer vaccines, and manage drug therapy under collaborative agreements with physicians. Michigan had not granted pharmacists general authority to prescribe hormonal contraception when this guide was checked. Services vary by pharmacy.
Insulin and cost-sharing caps
Michigan had no state insulin copay cap in force when this guide was checked, though bills have passed one chamber in past sessions. The federal Medicare Part D cap applies to Part D plans, and manufacturer self-pay programmes apply regardless of state. For cash-paying patients no cap applies.
Veterinary prescriptions
Gabapentin, one of the most prescribed drugs for dogs and cats, is a controlled substance in Michigan, so a veterinary gabapentin prescription has limited refills, cannot be transferred freely, and is reported to MAPS; a pet owner who changes pharmacies may need a new prescription. Veterinary prescriptions are exempt from the electronic-prescribing requirement. Michigan requires a veterinarian-client-patient relationship before prescribing, and veterinarians provide prescriptions on request.
