Unit-Dose Packaging in Hospital Pharmacy Explained

What Is Unit-Dose Packaging?

Unit-dose packaging is a medication distribution system where each dose of medication is individually packaged and labeled for a specific patient. It is the standard medication distribution method in hospital pharmacies and a commonly tested topic on the PTCB certification exam.

Why Hospitals Use Unit-Dose Systems

Unit-dose systems offer significant advantages over bulk dispensing:

Reduced medication errors: Each dose is pre-measured, reducing calculation and measurement errors
Better inventory control: Individual packaging allows precise tracking of medications
Reduced waste: Unused unit doses can be returned to stock (if packaging is intact)
Improved accountability: Each dose is documented from preparation to administration
Barcode compatibility: Unit-dose packages include scannable barcodes for bedside verification

Types of Unit-Dose Packaging

Manufacturer unit-dose: Medications packaged individually by the drug manufacturer, often in blister packs or strip packaging
Pharmacy-repackaged unit-dose: Bulk medications repackaged by the pharmacy into individual doses using automated packaging equipment
Oral syringes: Liquid oral medications measured into individual syringes for each dose

Repackaging Requirements

When pharmacy technicians repackage medications from bulk containers into unit-dose packaging, specific requirements must be followed:

Labeling: Each unit-dose package must include the drug name (generic and/or brand), strength, lot number, beyond-use date, and a barcode for scanning
Beyond-use dating: The BUD is the earlier of one year from repackaging or the manufacturer's expiration date (per USP standards)
Documentation: A repackaging log must record the drug, lot number, manufacturer, quantity repackaged, date, BUD assigned, and technician and pharmacist initials
Quality control: The pharmacist must verify the repackaged product for accuracy

Automated Dispensing Cabinets

Modern hospital unit-dose systems often integrate with automated dispensing cabinets (ADCs) like Pyxis and Omnicell. These secure, computerized cabinets are located in patient care areas and store unit-dose medications. Pharmacy technicians are responsible for restocking ADCs, verifying inventory, and managing expiring medications.

The 24-Hour Cart Fill

In many hospitals, pharmacy technicians prepare 24-hour medication carts for each nursing unit. Each cart contains patient-specific bins with all the unit-dose medications needed for the next 24 hours. This process requires meticulous attention to detail and is checked by a pharmacist before delivery.
