Of 6 patients with hyperemesis gravidarum, 3 had bipolar II disorder, and the others had major depressive disorder. Olanzapine was used alone in 3 cases. A daily dose of 2.5–5 mg was well tolerated and effective in all patients who had failed trials of conventional antiemetics. Thus, olanzapine may be a viable treatment for hyperemesis gravidarum in mood disorder patients unresponsive to standard antiemetics.</div></div>","PeriodicalId":16688,"journal":{"name":"Journal of obstetrics and gynaecology Canada","volume":"47 1","pages":"Article 102751"},"PeriodicalIF":2.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142879567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
