Study Notes

Prescription Overview

Unusual delays in prescription fulfillment can prompt pharmacist inquiries about physician intent and patient needs.
Essential components of a prescription include the Rx symbol, medication prescribed, dispensing directions, and prescriber information.

Rx Symbol or Superscription

Derived from the Latin verb "recipe," meaning "take thou."
Originally linked to the sign of Jupiter, the god of healing.
Represents a direct order from prescriber to compounder and signifies pharmacy at large.

Medication Prescribed (Inscription)

Key section listing names and quantities of medications for fabrication.
Includes types of names: proprietary (brand), nonproprietary (generic), and chemical.
Strength of medications may not be necessary if only one form is available; however, specifying strength is recommended to avoid misinterpretation.
Compounding orders require detailed listing of ingredients and their quantities.

Dispensing Directions to Pharmacists (Subscription)

Directions may specify preparation or compounding requirements.
Must include prescriber’s information: name, office address, and relevant identification numbers for controlled substances.

Electronic Prescribing (e-Prescriptions)

e-Prescribing employs electronic systems for generating and sending prescriptions, enhancing accuracy and efficiency.
Advantages: reduces errors from legibility, alerts for drug interactions, minimizes altered prescriptions, and offers patient convenience.

Medication Orders vs. Prescriptions

Medication orders are used in inpatient settings, while prescriptions apply to outpatient contexts.
Orders can be given verbally and submitted through various means including fax and computer systems.

Abbreviations and Symbols

Commonly used in prescriptions but can lead to confusion and errors if misinterpreted.
Important abbreviations include drug names (e.g., Pb for phenobarbital) and medical conditions (e.g., CHF for congestive heart failure).

Writing Prescriptions and Medication Orders

Latin terms were historically prevalent but have diminished; still used in some prescription sections.
Errors arise from illegible writing or misuse of abbreviations, highlighting the need for clarity and standardization.

Recommendations for Reducing Errors

Avoid decimals; use whole numbers without trailing zeros.
Ensure clarity by placing a zero before decimal points when needed.
Spell out full names of drugs instead of abbreviating to limit confusion.
Use USP designations for units of measure and avoid ambiguous abbreviations.
Incorporate tall man letters to differentiate similar drug names.
