Medication use in women of childbearing age (including pregnant women) was identified using pharmaceutical dispensing data for a 10% random sample of the Australian population. Pregnant social security beneficiaries (n = 111\u2009612) were age\u2010matched (1:3) to female social security beneficiaries in the 10% sample. For each medication, the risk it was dispensed during pregnancy relative to being dispensed during an equivalent time period among matched controls was computed. Medications were mapped to Australian pregnancy risk categories.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 181 included medications, 35 were statistically significantly more commonly dispensed to pregnant women than control women. Of these, 23 are categorised as posing no increased risk to the foetus. Among medications suspected of causing harm or having insufficient safety data, the strongest associations were observed for hydralazine, ondansetron, dalteparin sodium and ranitidine. Use was less likely during pregnancy than control periods for 127 medications, with the strongest associations observed for hormonal contraceptives and progestogens.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Most medications found to be used disproportionately more by pregnant women are indicated for pregnancy\u2010related problems. A large number of medications were used disproportionately less among pregnant women, where avoidance of some of these medications may pose a greater risk of harm. For many other medications avoided during pregnancy, current data are insufficient to inform this risk\u2010benefit assessment.<\/jats:p><\/jats:sec>","DOI":"10.1002\/pds.5131","type":"journal-article","created":{"date-parts":[[2020,9,16]],"date-time":"2020-09-16T07:30:10Z","timestamp":1600241410000},"page":"53-64","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Medications used disproportionately during pregnancy: Priorities for research on the risks and benefits of medications when used during pregnancy"],"prefix":"10.1002","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6563-8804","authenticated-orcid":false,"given":"Alys","family":"Havard","sequence":"first","affiliation":[{"name":"Centre for Big Data Research in Health (CBDRH) University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastiano","family":"Barbieri","sequence":"additional","affiliation":[{"name":"Centre for Big Data Research in Health (CBDRH) University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Hanly","sequence":"additional","affiliation":[{"name":"Centre for Big Data Research in Health (CBDRH) University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar","family":"Perez\u2010Concha","sequence":"additional","affiliation":[{"name":"Centre for Big Data Research in Health (CBDRH) University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duong T.","family":"Tran","sequence":"additional","affiliation":[{"name":"Centre for Big Data Research in Health (CBDRH) University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debra","family":"Kennedy","sequence":"additional","affiliation":[{"name":"Royal Hospital for Women MotherSafe  Sydney New South Wales Australia"},{"name":"School of Women's and Children's Health University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louisa R.","family":"Jorm","sequence":"additional","affiliation":[{"name":"Centre for Big Data Research in Health (CBDRH) University of New South Wales  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,9,16]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/pds.2184"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/14740338.2017.1363177"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/bcp.13438"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2125.2008.03102.x"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.2147\/CLEP.S16305"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00228-003-0584-4"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10995-015-1878-8"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/pds.4409"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2003.10.024"},{"key":"e_1_2_10_11_1","unstructured":"Department of Health.
