Miss. Code § 73-45-1
Health care professionals licensed by an agency of this state and whose practice encompasses the prescribing and dispensing of drugs or medical devices shall automatically provide the patient with a prescription containing all of the necessary information to allow any prescription provider to dispense the drug or medical device to the consumer. Upon the request of another health care professional or prescription provider to confirm prescription information for a specified individual, the prescribing health care professional shall immediately confirm all necessary information to enable the person requesting verification to accurately dispense the drug or medical device. Confirmation may be requested or confirmed in any form, including electronically. If confirmation of the verification request for the drug or medical device is not received within one (1) hour following the request, all information contained in the request, including the fact that the prescription has not expired, shall be presumed accurate, and the provider shall be authorized to dispense pursuant to the prescription. If no expiration date is included on the prescription, the prescription shall expire two (2) years after the date of issue. Health care professionals who dispense prescription medical devices shall prescribe brands that are readily and directly available to all channels of distribution, and shall post a notice in the location where payment for services is made informing patients as follows: "You have a right to receive a copy of your prescription. You also have a right to have your prescription filled wherever you choose."
