8.1 Counting, Packaging & Dedicated Equipment
Key Takeaways
- USP <800> requires equipment used to count or package hazardous drugs (trays, spatulas) to be dedicated solely to HD use, clearly labeled, and never shared with non-HD counting equipment.
- Dedicated HD equipment must still be cleaned per SOP after every single use — dedication prevents cross-contamination with non-HD prescriptions, while cleaning prevents drug-to-drug residue carryover between different HDs.
- Tablet and capsule forms of antineoplastic hazardous drugs must never be run through automated counting or packaging machines; the mechanical stress of hoppers and chutes can chip or abrade tablets and release powder that contaminates the machine and every prescription counted on it afterward.
- Manual counting by hand, using dedicated equipment, is standard practice for HD final dosage forms because most automated counting machines were never validated to be decontaminated to the standard HD handling requires.
- ASTM D6978-tested chemo gloves must be worn any time an HD final dosage form is counted or packaged, regardless of whether the count is manual or automated.
Counting, Packaging & Dedicated Equipment
Once a hazardous drug (HD) has been compounded and verified, or once a commercially manufactured HD tablet arrives ready to dispense, a technician still has to count out the correct quantity and package it for the patient. This is one of the most routine tasks in any pharmacy, but under the Dispensing Final Dosage Forms domain of the exam, counting and packaging are treated as genuine contamination-control points — not just clerical steps. Unlike compounding, which happens inside a certified primary engineering control, counting a manufactured tablet typically happens on an open bench or through shared equipment, so the only barriers protecting the next patient and the next technician are dedicated equipment, correct PPE, and disciplined packaging.
Why Counting Is a Contamination Control Point
A tablet or capsule can carry trace hazardous residue on its surface even when it looks intact — from manufacturing, from the coating itself, or from contact with other tablets during shipping. Any equipment that touches that tablet can pick up that residue and pass it to the very next item counted on the same surface. If that next item is a routine antibiotic for an unrelated patient, including a child, that patient is exposed to a cytotoxic residue with zero clinical justification. USP <800> closes this gap with two linked rules: dedicated equipment and a ban on automated machines for antineoplastic tablets and capsules.
Dedicated Equipment Requirement
| Requirement | Detail |
|---|---|
| Equipment type | Counting trays, spatulas, and related handling tools |
| Dedication | Used ONLY for hazardous drugs — never shared with equipment used to count non-HD prescriptions |
| Labeling | Clearly labeled or marked (e.g., "HD Use Only") and physically stored/segregated apart from general-use equipment |
| Cleaning | Cleaned per the facility's written SOP after every single use, even though the equipment is dedicated |
Dedication solves the cross-contamination problem between HD and non-HD prescriptions. It does not, by itself, solve contamination carryover between two different HDs counted back-to-back on the same tray — that is what the mandatory post-use cleaning step addresses. A technician who reasons "it's a dedicated HD tray, so it doesn't need cleaning between uses" has the rule backwards: dedication and cleaning are two separate controls that both apply, every time.
The Automated Counting Machine Prohibition
The highest-yield fact in this section: tablet and capsule forms of antineoplastic hazardous drugs must not be placed in automated counting or packaging machines. These machines move tablets through hoppers, chutes, and vibrating trays to count them quickly, and that same mechanical action — vibration, sliding, tablet-on-tablet impact — can abrade a tablet's coating or chip it outright, releasing hazardous powder into the machine's internal mechanism. That residue then contaminates every subsequent prescription counted on the machine, exposes any staff member who services or cleans it, and cannot reliably be removed because most automated counters were never designed or validated for HD decontamination. For this reason, manual counting by hand — using the dedicated tray and spatula described above — is the standard practice for HD final dosage forms at most sites, even though it is slower than machine counting.
PPE During Counting and Packaging
Chemo gloves tested to ASTM D6978, the permeation-resistance standard used for chemotherapy-drug gloves, must be worn whenever a technician counts or packages any HD final dosage form — manually or otherwise. This applies even to a tablet that appears fully intact, because surface residue is not visible, and the requirement does not depend on which counting method is used.
Packaging Considerations
Once counted, HD prescriptions must be packaged and labeled in a way that alerts the next people in the chain — the verifying pharmacist, delivery or mail staff, a caregiver, and the patient — that hazardous or cytotoxic contents are inside, along with any special handling or disposal instructions. This is typically done with an auxiliary warning label on the prescription container. At the same time, the outer packaging must not violate the patient's privacy: a shipping box or bag should never display information that would let anyone outside the household infer a diagnosis, even while it correctly flags that special handling is required.
Exam Scenario
A technician is about to fill a prescription for tamoxifen 20 mg #60 using the pharmacy's electronic tablet-counting machine — the same machine used moments earlier for a child's routine amoxicillin refill. Tamoxifen is an antineoplastic HD tablet, so it must never go through the automated counter. The correct sequence is: recognize the drug as an HD, do not use the shared electronic counter, don ASTM D6978 chemo gloves, retrieve the pharmacy's dedicated HD counting tray and spatula (never the tray just used for the amoxicillin), count the tablets by hand, clean the dedicated tray per SOP before returning it to storage, and apply an auxiliary hazard warning label during packaging before the prescription reaches pickup or shipping.
Key Takeaways for the Exam
- Counting/packaging equipment for HDs (trays, spatulas) must be dedicated solely to HD use, clearly labeled, and never shared with non-HD equipment.
- Dedicated equipment still requires cleaning per SOP after every use — dedication and cleaning are separate, both-required controls.
- Antineoplastic HD tablets and capsules must never be counted or packaged using automated machines, because mechanical stress can chip tablets and spread powder contamination to every later prescription.
- Manual counting is the default for HD final dosage forms since most automated counters cannot be validated for HD decontamination.
- ASTM D6978 chemo gloves are required during any HD counting or packaging task, and packaging must warn downstream handlers of hazardous contents without exposing patient privacy.
A pharmacy currently uses one shared counting tray for every oral prescription filled during the shift. Under USP <800>, what must change when a hazardous drug (HD) tablet needs to be counted?
Why are automated pill-counting machines prohibited for tablet and capsule forms of antineoplastic hazardous drugs?
Which glove standard applies to chemo gloves worn during the counting or packaging of an HD final dosage form?
A dedicated HD counting tray has just been used to count one prescription. Later that same shift, it will be needed to count a different HD prescription. What must happen to the tray between those two uses?
