What constitutes a valid prescription?

A valid prescription is an order for drugs or medical supplies, written and signed and then
transmitted by telephone, fax or other means of communication with a pharmacist. The
licensed physician or practitioner must be authorized by law to prescribe and administer such
drugs or medical supplies. The prescription must be issued in compliance with all applicable
rules and regulations of the regulatory authority by an individual licensed or authorized to
prescribe a product. The prescription can only be used by a named and identifiable individual
for an authentic medical purpose.

What makes up the 9 parts of a legal prescription?

  • Date the prescription was written
  • Name and address of the patient
  • Name of drug or drug product
  • Strength of drug and dosage form
  • Route of administration
  • Quantity to be dispensed
  • Instructions for use
  • Number of refills if any
  • The prescriber’s name and phone number
  • The prescriber’s signature

A prescription which is written in code does not provide acceptable information for clarification
of the prescription and therefor, the dispensing of the drug product is considered an invalid
prescription. The dispensing of prescription drugs or controlled substances by a
physician/patient affiliation must include a qualified and licensed medical practitioner and must
include an appropriate examination of the patient and include an established diagnosis in order
to qualify as a valid prescription.
