Mississippi Prescription Pads

In addition to the federal requirements, Mississippi state law requires that each prescription written in this state shall contain two signature lines, either of which, when signed by the prescriber, shall validate the prescription and, depending upon which line the prescriber's signature appears, will indicate the prescriber's approval or denial of drug product selection by the pharmacist. The two line provision of the prescription and the prescriber's approval or denial of drug product selection shall be as follows:

• There shall be a signature line in the lower right-hand corner of the prescription form beneath which shall be imprinted the words "Substitution Permitted".
• There shall be a signature line in the lower left-hand corner of the prescription form beneath which shall be imprinted the words "Dispense as Written".
