Hyperemesis Gravidarum with Metabolic Disturbance When Fourth-Line Antiemetic Therapy Has Failed
Clinical scenario
This protocol applies to patients with hyperemesis gravidarum with metabolic disturbance who have not achieved adequate control of nausea and vomiting despite fourth-line pharmacotherapy, including antiemetic agents and intravenous hydration.
Previous line: escalation trigger
Fourth-line pharmacotherapy — including Ondansetron and, where reflux is also present, Famotidine or Omeprazole — represents the prior treatment step. Escalation to this fifth-line protocol occurs when that approach fails to achieve sufficient reduction in the severity and frequency of nausea and vomiting.
Fifth-line approach (partial overview)
This protocol introduces corticosteroid-based pharmacotherapy, reserved strictly for situations in which antiemetic medications and intravenous hydration have not been sufficient. Careful blood glucose monitoring is an integral component of management throughout this therapy.
The complete regimen — specific agents, sequencing, and full monitoring parameters — is available in the structured protocol.
Treatment goals
Resolution of severe nausea and vomiting, with blood glucose monitored to remain free of hyperglycaemia during steroid therapy.
