Study design details

• Main study objective:
  This aim was to identify use of ondansetron in women during pregnancy in France and Germany as identified in the IMS Disease Analyzer (DA) databases. Due to concern that ondansetron may be increasingly used for hyperemesis gravidarum a further aim was to study the yearly proportion of women with a diagnosis of excessive vomiting of pregnancy treated with ondansetron between 2005 and 2018.
• Data analysis plan:
  The yearly number of pregnant women was calculated and the number of pregnant women with a prescription for ondansetron during the time of pregnancy was presented. The proportion of women with a diagnosis of hyperemesis gravidarum that had received a prescription for ondansetron was calculated.
