Medication
SSRI
Selective serotonin reuptake inhibitor
Risk
ISMP flags SSRI/SSI as error-prone: sliding scale regular insulin may be mistaken as selective serotonin reuptake inhibitor.
Safer Alternative
Write "sliding scale insulin" or spell out the antidepressant class fully
Example
SSRI for depression
Source Note
SSRI is a real antidepressant-class abbreviation; ISMP flags it in medication-order contexts because of SSRI/SSI confusion.
