2.1 What is a Prescription?

A prescription is an authorization from an authorized prescriber directing a pharmacist to dispense a medication for a specific patient.

In community pharmacy practice, a prescription is more than a medication order. It is a legal, clinical, and professional record that allows the pharmacy team to prepare the medication, document the dispensing process, and support safe patient care.

Learning Objectives
🎯 After completing this lesson, you should be able to:
  • ✅ Define a prescription and its purpose in pharmacy practice
  • ✅ Identify the key elements of a complete prescription
  • ✅ Differentiate between written, electronic, faxed, and verbal prescriptions
  • ✅ Recognize the pharmacy assistant's role in prescription processing

A Prescription Contains Important Information About:

  • The patient — name, address, date of birth, or other identifying details depending on pharmacy policy.
  • The medication — drug name, strength, dosage form, and quantity.
  • The dosage — how much medication the patient should take or use.
  • The directions for use — frequency, route, timing, and any special instructions.
  • The prescriber — name, contact information, signature or electronic authorization, and professional designation.

Why Prescriptions Are Important

Prescriptions help ensure that medication therapy is appropriate, documented, and reviewed by regulated healthcare professionals.

  • Appropriate treatment
  • Safe medication use
  • Professional oversight
  • Accurate record keeping
  • Legal accountability

Electronic Prescription

A prescription created, signed, and transmitted electronically from the prescriber to the pharmacy.

Faxed Prescription

A prescription sent directly from the prescriber's office to the pharmacy by fax.
