About this trial

The investigator team proposes a randomized, double-blind, double-dummy comparative effectiveness trial conducted in two urban emergency departments (EDs) in the Bronx, New York. This study is designed to determine the relative efficacy of IV acetaminophen compared to PO acetaminophen in treating pelvic pain. This design focuses on the early onset of action and short-term efficacy, which may better capture potential differences between IV and PO acetaminophen in the acute ED setting.
