There was a significant rising trend of prenatal antidepressant use over time (0.6% in 2003 to 1.3% in 2018; odds ratio: 1.09, 95% confidence interval = [1.08, 1.10], p\u2009&lt;\u20090.001). A consistent pattern of decreasing overall antidepressant use from 3\u2009months pre-pregnancy to the second trimester was observed, followed by a slight increase in the third trimester. Almost half ( n\u2009=\u2009949, 49.5%) of 1918 women on antidepressants in 3\u2009months pre-pregnancy continued treatment beyond the first trimester. A total of 8.2% that discontinued antidepressants in 3\u2009months pre-pregnancy or in the first trimester reinitiated treatment in the later stage of pregnancy. Older age at conception (\u2a7e35\u2009years), recent calendar year of delivery (2015\u20132018), pre-existing depression\/anxiety disorders, longer-term pre-pregnancy antidepressant treatment and pre-pregnancy prescription of other psychotropics were significantly associated with antidepressant continuation. Antidepressant reinitiation was predicted by pre-existing depression\/anxiety disorders.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
