What it means

Often shortened to LASA. Pairs such as hydroxyzine and hydralazine, or Celebrex and Celexa, have been mixed up when ordering, dispensing or giving drugs. ISMP keeps a list of confused drug names. Safeguards include "tall man" lettering (hydrOXYzine, hydrALAZINE), storing such drugs apart, and adding the purpose of the drug to orders.

For the nurse

Read the label carefully at every check, scan barcodes, and confirm that the drug makes sense for the client's diagnosis. Question any order that does not fit.
