Pharmacy rules in Connecticut
Connecticut caps cost-sharing for insulin and other diabetes medicines at one of the lowest levels in the country, lets pharmacists prescribe hormonal contraception, requires controlled-substance prescriptions to be electronic, limits first opioid prescriptions, and regulates pharmacy through a commission within the Department of Consumer Protection.
Connecticut Commission of Pharmacy (Department of Consumer Protection): licence lookup and complaintsGeneric substitution
A Connecticut pharmacist may substitute a generic equivalent unless the prescriber has indicated “brand medically necessary” on the prescription or electronically. 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 Connecticut 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. Connecticut requires controlled-substance prescriptions to be sent electronically, with exceptions.
Controlled substances
Connecticut’s Prescription Monitoring and Reporting System (CPMRS) must be checked by prescribers before prescribing most controlled substances for more than a short period, and pharmacies report every controlled dispensing. First opioid prescriptions for adults are limited to a seven-day supply and for minors to five days, with documented exceptions. Schedule II prescriptions cannot be refilled; Schedule III to V may be refilled up to five times within six months. Gabapentin was not scheduled in Connecticut when this guide was checked. A Schedule II prescription may be transferred electronically once under the federal rule.
What a pharmacist can prescribe or furnish
Connecticut pharmacists may prescribe hormonal contraception, including emergency contraception, under prescriptive authority in place since 2024; they may also dispense naloxone, administer vaccines, and manage drug therapy under collaborative agreements. Each service depends on the pharmacy offering it, so ask.
Insulin and cost-sharing caps
Connecticut caps cost-sharing on state-regulated health plans for a thirty-day supply of insulin or other diabetes medicines at a low fixed amount, and separately caps diabetes devices and supplies, under a 2020 law; 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.
Veterinary prescriptions
A veterinarian’s prescription for a human drug is filled by a Connecticut pharmacy under the same substitution rules; the electronic requirement for controlled substances applies to veterinarians with exceptions. The Connecticut Board of Veterinary Medicine requires a veterinarian-client-patient relationship before prescribing, and veterinarians provide prescriptions on request.
