Preparing Prescriptions: Product Selection and Counting
- Differentiate the pharmacy technician's dispensing responsibilities from the pharmacist's legal duties regarding clinical judgment, prescription verification, and patient counseling.
- Apply rigorous product selection standards using National Drug Codes, barcode scanning, lot numbers, and Tall Man lettering to prevent dispensing errors.
- Execute safe counting, measuring, and reconstitution techniques for oral dosage forms using manual tools and automated technology.
The Technician's Role and Prescription Intake Security
Pharmacy technicians prepare prescriptions under pharmacist supervision in accordance with applicable state law; the required form of supervision varies by jurisdiction. Within the dispensing workflow, duties are strictly divided. The pharmacist is responsible for clinical judgment, drug utilization review, and final verification. Technicians must refer all clinical issues directly to the pharmacist. Furthermore, medication counseling is legally provided by a pharmacist or, where permitted, a supervised pharmacy intern. Technicians do not counsel patients under any circumstances.
Before selecting products, technicians should screen written orders for missing information or signs of alteration and refer concerns about an order's validity to the pharmacist. Federal Medicaid rules generally require tamper-resistant paper for written outpatient prescriptions for covered drugs, subject to specified exceptions. Tamper-resistant prescription pads must feature three key security layers: elements that prevent unauthorized copying (such as a hidden 'VOID' pantograph), features that prevent erasure or alteration (such as chemical-reactive paper), and security features to prevent the use of counterfeit forms (such as pre-printed serial numbers or watermarks).
Technicians must remain alert for potential fraud when examining paper prescriptions. Discrepancies in ink color, altered handwriting, or differing numerical and written quantities are common red flags for prescription forgery. When handling controlled-substance prescriptions, unusually high quantities, early refill attempts, and a missing or invalid prescriber DEA number can also be red flags for fraud. If a technician suspects that an order is fraudulent, they must immediately notify the supervising pharmacist rather than attempting to resolve the matter independently.
Common mistakes
- Overriding clinical alerts: Assuming software warning alerts can be clicked through or cleared by the technician. Clinical safety alerts must never be bypassed by a technician and require pharmacist review.
- Misinterpreting month-year expiration dates: Treating an expiration date of '06/2026' as expired on June 1st. Unless specified otherwise by the manufacturer, the drug remains usable through the final day of that month (June 30, 2026).
- Measuring liquids in oversized containers: Choosing a large graduate for a small volume. Technicians should always select the smallest graduate or syringe that can comfortably hold the target volume to ensure accuracy.
- Failing to loosen compacted powder prior to reconstitution: Pouring water directly into caked powder without tapping the container first, which can cause powder to clump and prevent complete, uniform mixing.
Key points
- Pharmacy technicians prepare prescriptions under pharmacist supervision, while clinical judgment, DUR, patient counseling, and final verification remain strictly with the pharmacist.
- Federal Medicaid rules generally require written outpatient prescriptions for covered drugs to be on tamper-resistant paper with features addressing copying, alteration, and counterfeiting; specified exceptions apply.
- The 3-segment National Drug Code identifies the labeler, product details (strength, form, formulation), and package type/size; barcode scanning and NDC cross-checks prevent stock selection errors.
- Tablets and capsules are manually counted in groups of five on a clean tray; dedicated, labeled trays and spatulas and specialized cleaning protocols are required for hazardous drugs and potent allergens.
- Automated counting devices use optical sensors that require regular cleaning to prevent tablet dust from causing inaccurate counts.
- Liquid measuring requires the smallest appropriate graduate, reading clear liquids at the bottom of the meniscus at eye level, with cylindrical graduates offering superior accuracy over conical ones.
- Powder reconstitution requires tapping the bottle to loosen powder, using the manufacturer-specified diluent, calculating the beyond-use date, and affixing appropriate auxiliary labels like 'Shake Well'.
