Abstract

The Patient Safety Authority has received multiple reports to the Pennsylvania Patient Safety Reporting System (PA-PSRS) describing erroneous dispensing and administration of whole bottle contents (up to 25 tablets) of sublingual nitroglycerin instead of a single tablet. As a result of these events, patients have required resuscitative measures and/or transfer to a higher level of care.
