Pharmacy rules in Tennessee
Tennessee allows generic substitution unless the prescriber indicates the brand is medically necessary, schedules gabapentin as a controlled substance, requires controlled-substance prescriptions to be electronic, has some of the tightest first-opioid limits in the country, and had no state insulin cap in force when this guide was checked.
Tennessee Board of Pharmacy: licence lookup and complaintsGeneric substitution
A Tennessee pharmacist may substitute a generic equivalent unless the prescriber has written “dispense as written”, “medically necessary” or the equivalent on the prescription or indicated it electronically. The pharmacist must tell the patient about the substitution, and the patient may refuse it. Substitution follows the FDA’s therapeutic equivalence list, and interchangeable biological products may be substituted with notice to the prescriber.
Moving a prescription between pharmacies
Non-controlled prescriptions can be transferred between Tennessee pharmacies without a state limit on transfers. 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. Tennessee requires controlled-substance prescriptions to be electronic, with exceptions, but not non-controlled prescriptions.
Controlled substances
Tennessee schedules gabapentin as a Schedule V controlled substance, so gabapentin prescriptions carry the refill, transfer and reporting rules of a controlled drug and are reported to the Controlled Substance Monitoring Database, which prescribers must check before prescribing most controlled substances. First opioid prescriptions for acute pain are limited to a three-day supply in most cases, with longer limits allowed only with documented exceptions. 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
Tennessee pharmacists may dispense naloxone under a statewide standing order, administer vaccines, and manage drug therapy under collaborative agreements. Tennessee had not granted pharmacists general authority to prescribe hormonal contraception when this guide was checked. Services vary by pharmacy.
Insulin and cost-sharing caps
Tennessee had no state insulin copay cap in force when this guide was checked. The federal Medicare Part D insulin 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 is a controlled substance in Tennessee, so a veterinary gabapentin prescription for a dog or cat has limited refills, cannot be transferred freely between pharmacies and is reported to the monitoring database under the owner; the electronic requirement for controlled prescriptions applies to veterinarians with exceptions. The Tennessee Board of Veterinary Medical Examiners requires a veterinarian-client-patient relationship before prescribing, and veterinarians provide prescriptions on request.
