Louisiana Prescription Pads

In addition to the federal requirements, Louisiana state law requires a written prescription to

conform to the following format:

• The prescription form shall be of a size not less than 4 inches by 5 inches, and shall bear a single printed signature line.
• The prescription form shall clearly indicate the authorized prescriber’s name, licensure designation, address, telephone number, and, if for a controlled substance, the Drug Enforcement Administration (DEA) registration number. In the event that multiple practitioners are identified on the prescription form, the authorizing prescriber’s specific identity shall be clear and unambiguous. This identification may be indicated by any means, including but not limited to, a marked check box next to, or circling the authorizing prescriber’s printed name.
• No prescription form shall contain more than four prescription drug orders. Each prescription drug order recorded on the form shall provide the following:
  • check box labeled “Dispense as Written”, or “DAW”, or both; and
  • the number of refills, if any.
• The prescription shall be written with ink or indelible pencil, typewriter, or printed on a computer printer and shall be manually signed by the practitioner on the date issued and in the same manner as he would sign a check or legal document (e.g., J. H. Smith or John H. Smith). Examples of invalid signatures include rubber stamps, signatures of anyone other than the prescriber, and computer generated signatures.
