Drug Names That Look and Sound Alike

Dispensing errors can be caused by drug names that look alike and sound alike. The list below contains several such combinations. Some similarities sound dangerously close while others may appear more obviously different. In both circumstances good communication skills are vital when dealing with these drugs.

This list has been prepared to sensitize health professionals and their support personnel for the neeed to properly communicate when writing, speaking, reading, and hearing drug names.

Trade names are capitalized and italicized, whereas other names are in regular face and lower case letters.

“Look-Alike, Sound-Alike Drugs” was originated and developed by Benjamin Teplitsky, retired Chief Pharmacist of Veterans Administration Hospitals in Albany, NY and Brooklyn, NY.
