Tom Guttuso, MD, University at Buffalo
Loralei Thornburg, MD, University of Rochester Medical Center
Has required at least 1 round of IV fluids.
Has daily emesis for 2 weeks despite trying at least one anti-emetic.
Has 3-4+ketonuria or >5% weight loss from pre-pregnancy weight.
Ultrasound confirmed singleton pregnancy.
Study participants will be randomly assigned to take either gabapentin (Neurontin)* or ondansetron (Zofran) without knowing which one they are taking.
During the two-week study period, women participating in the study will be asked to stop any other treatments for nausea and vomiting, complete a daily form to track symptoms, and complete questionnaires during study visits.
Participants will have an opportunity to participate in the open-label gabapentin phase of the study for another period of two weeks or longer.
* Gabapentin is not approved by the FDA to treat HG, but is approved to treat nerve pain and seizures.
