Pharmacy rules in Washington, D.C.
The District of Columbia caps insulin and diabetes-device cost-sharing on plans it regulates, has authorized pharmacist-provided contraception under a protocol, runs its own prescription monitoring program through DC Health, and allows generic substitution unless the prescriber indicates otherwise.
District of Columbia Board of Pharmacy (DC Health): licence lookup and complaintsGeneric substitution
A District of Columbia pharmacist may substitute a less expensive generic equivalent unless the prescriber has indicated on the prescription, or electronically, that the brand is required. The pharmacist must tell the patient about the substitution, and the patient may refuse it and pay for the brand. 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 District of Columbia 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. Many residents also fill prescriptions in Maryland and Virginia; transfers between pharmacies in different jurisdictions follow the same rules. Check DC Health for the current electronic-prescribing requirements for controlled substances.
Controlled substances
The District’s Prescription Drug Monitoring Program, run by DC Health, collects every controlled dispensing and is checked by prescribers before prescribing opioids and other controlled substances in many situations. Gabapentin was not scheduled in the District when this guide was checked, though it is controlled across the river in Virginia. 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
The District has authorized pharmacists to provide hormonal contraception under a protocol; check DC Health for when and how it is in effect. Pharmacists may also dispense naloxone, administer vaccines, and manage drug therapy under collaborative agreements. Services vary by pharmacy.
Insulin and cost-sharing caps
The District caps cost-sharing for insulin on the health plans it regulates at a low fixed amount per thirty-day supply, and separately caps covered diabetes devices; the caps do not apply to self-funded employer plans, federal employee plans or patients paying cash. The federal Medicare Part D cap applies to Part D plans.
Veterinary prescriptions
A veterinarian’s prescription for a human drug is filled by a District pharmacy under the same rules as any outside prescription. A pet gabapentin prescription filled in Virginia is subject to Virginia’s controlled-substance rules. The DC Board of Veterinary Medicine requires a veterinarian-client-patient relationship before prescribing, and veterinarians provide prescriptions on request.
