Treatment of Excessive Vomiting in Pregnancy When Earlier Antiemetics Have Not Worked
Excessive vomiting in pregnancy can persist despite initial antiemetic treatment. When prior therapies are ineffective or poorly tolerated, a fourth-line pharmacotherapy step exists — and concurrent reflux, when present, may also be a factor driving ongoing symptoms.
Clinical scenario: Persistent nausea and vomiting in pregnancy that has not responded adequately to earlier antiemetic treatment, including cases where gastrointestinal reflux may be contributing to the symptom burden.
Approach: This protocol uses a fourth-line antiemetic agent — available in multiple formulations — for cases where earlier antiemetics have failed or are not tolerated. It also addresses reflux as a potential contributor. The complete regimen, including agent selection, formulation options, and full sequencing, is contained in the structured protocol.
