What is a look-alike/sound-alike (LASA) drug risk, and how can facilities mitigate it?

• A. LASA drugs have similar names or appearances that can cause confusion.
• B. LASA is about packaging color only.
• C. LASA risk can be mitigated with independent double checks.
• D. LASA drugs have similar names or appearances that can cause confusion; mitigate with tall-man lettering, color-coding, distinct packaging, and independent double checks.

Answer: (D)

Look-alike/sound-alike risk happens when drugs have names or appearances that are so similar that people can easily confuse them during prescribing, dispensing, or administering. That confusion can lead to selecting the wrong medication, the wrong dose, or the wrong patient, which can cause preventable harm, especially in fast-paced or high-stress situations or when packaging looks alike.

Mitigation requires more than a single tactic. Using tall-man lettering highlights the distinguishing parts of similar names to reduce misreading or mispronunciation. Color-coding and distinct packaging help create immediate visual separation between products, making it harder to grab the wrong drug at a glance. Storing LASA drugs in separate, clearly labeled areas or using distinct labeling and packaging further reduces mix-ups. Independent double checks provide an extra layer of verification, particularly for high-risk medications, and barcode scanning with decision support helps catch errors at dispensing and administration. Ongoing staff education and monitoring for near-misses or actual errors keep the program effective and adapt to new LASA risks as they arise.
