This case suggests that metoclopramide-induced akathisia can occur during pregnancy and may be misdiagnosed as a perinatal anxiety disorder. Rapid intravenous bolus administration is a known risk factor for metoclopramide-induced akathisia and may have increased the risk in this patient. In addition, a possible pharmacological interaction between metoclopramide and dextromethorphan, including a potential CYP2D6-related pharmacokinetic effect and central dopaminergic pharmacodynamic effect, may have contributed to akathisia. Greater awareness of this adverse effect may facilitate early recognition and appropriate management.
