What measure best mitigates look-alike/sound-alike (LASA) drug name errors?

• A. Rely on staff memory
• B. Ignore minor similarities
• C. Tall man lettering and verification with the patient/prescriber
• D. Use the same name for all products

Answer: (C)

Look-alike/sound-alike drug name errors happen when names resemble each other, leading to misidentification during prescribing or dispensing. The best way to reduce these mistakes combines visual differentiation with a real-time safety check. Tall Man lettering uses mixed case to highlight the differing letters within similar drug names, making them easier to distinguish at a glance on orders, labels, and computer screens. Pairing this with verification with the patient or prescriber adds a direct confirmation step that the right drug and dose are being used, catching potential mix-ups before they reach the patient.

Relying on memory isn’t reliable because humans forget or mix up similar names, especially in busy settings. Ignoring minor similarities leaves obvious risks unaddressed, and using the same name for all products would create more confusion, not less. So the combination of visual differentiation and active verification specifically targets the ways LASA errors occur, making it the most effective approach.
