Regulatory implementation of controls on prescription devices is a state issue. In most states, prescription dispensation of prescription-only devices to lay users is done primarily under the authority of pharmacists, and is regulated by a state Board of Pharmacy or a similar body.
Prescription devices of course also can be sold directly to a physician or dentist, who as a matter of law are empowered to order prescriptions and thus to dispense, or to a business or other organization under the supervision of a physician, such as a hospital or clinic.
Veterinarians and (in some states and clinical settings, in some cases with limited scope) podiatrists, optometrists, nurse practitioners and other advanced clinicians also can order and dispense, and thus can be sold to.
In most states, a distributorship that does not operate with supervisory participation by a licensed professional and hold a state license cannot legally dispense prescription devices to lay users, but can sell such devices to professional users and associated businesses/organizations. Sales of prescription devices should be documented as to buyer and chain of custody.
