Identifying High-Alert and LASA Medications — Practice Checklist
Walk through all 5 steps in order. Use this to build the habit until the sequence is automatic.
Step-by-Step Procedure (5 steps)
- 1.
Know the categories of high-alert medications: these carry a heightened risk of significant patient harm when used in error, even though the error itself may be no more likely than with any other drug — examples include insulin, anticoagulants (e.g., warfarin, heparin), opioids, and concentrated electrolytes.
- 2.
Recognize common look-alike/sound-alike (LASA) pairs by sight and by name before pulling stock — e.g., hydroxyzine vs. hydralazine, clonidine vs. klonopin (clonazepam), Celebrex vs. Celexa.
- 3.
Use Tall Man lettering cues where your pharmacy system displays them (e.g., hydrOXYzine vs. hydrALAzine) as a deliberate visual check, not just a formatting detail to skim past.
- 4.
Physically separate high-alert and LASA-paired products on the shelf where your pharmacy's layout allows it, and double-check the product in hand against the order before counting.
- 5.
Involve the pharmacist for an independent check on any high-alert medication fill, per your pharmacy's SOP — these typically require verification beyond the technician's initial check.
Quality Checkpoints (3)
Confirm each of these before considering the task complete.
High-alert medications are identified as such and routed through any extra verification step your pharmacy requires.
LASA pairs are checked by reading the full name, not a glance at the first few letters.
Tall Man lettering, when present, is read and used as an active cross-check, not ignored.
Avoid These Mistakes
- ⚠
Grabbing a bottle based on a quick glance at the first syllable of the drug name — this is exactly how LASA errors happen.
- ⚠
Treating "high-alert" as a label rather than a trigger for an actual extra verification step.
- ⚠
Not recognizing that a drug can be ordinary-risk in one form/strength and high-alert in a concentrated or injectable form (e.g., concentrated electrolyte solutions).
