Common Mistakes: Filling and Labeling a Prescription
These are the specific ways this task goes wrong on the job — not hypothetical edge cases, but patterns that cause real dispensing errors, insurance problems, or patient safety issues.
Matching on drug name and strength alone and skipping the NDC check — different manufacturers' versions of the same drug/strength have different NDCs, and the wrong one can mean the wrong formulation or an insurance rejection.
Using a counting tray that was just used for a different drug without cleaning it, risking cross-contamination of trace powder.
Transcribing the Sig in the technician's own words instead of the prescriber's exact wording, which can silently change the instructions.
Skipping the auxiliary label step because "the patient probably knows."
Not flagging a prescription for pharmacist review when something looks off (unusual dose, drug interaction flag, early refill) — technicians are not permitted to make that call themselves.
How the Quality Checkpoints Prevent These
Every mistake above is caught by one of this task's quality checkpoints — the habit of checking these consistently is what actually prevents the error, not just knowing it exists.
- ✓
NDC on the stock bottle matches the NDC selected in the system — not just a name-and-strength match.
- ✓
Counted/measured quantity matches the prescribed quantity exactly.
- ✓
Label directions match the prescriber's Sig exactly, including any PRN instructions.
- ✓
Lot number and expiration date are current and documented where required.
- ✓
A pharmacist performs final verification before the prescription leaves the pharmacy — technicians do not release a never-verified fill.
