Type: cohort study The Huybrechts study Data from pregnant women and infants enrolled in Medicaid Included a total of 3,789,330 women Huybrechts, K. et al (2015). Antidepressant use late in pregnancy and risk of persistent pulmonary hypertension of the newborn. JAMA, 313(21), 2142-2151.
Type: cohort study The Huybrechts study 3.4 % used antidepressants Huybrechts, K. et al (2015). Antidepressant use late in pregnancy and risk of persistent pulmonary hypertension of the newborn. JAMA, 313(21), 2142-2151.
Type: cohort study The Huybrechts study 2.7 % SSRIs 3.4 % used antidepressants 0.7 % Non-SSRIs Huybrechts, K. et al (2015). Antidepressant use late in pregnancy and risk of persistent pulmonary hypertension of the newborn. JAMA, 313(21), 2142-2151.
Incidence of PPHN Unexposed: 21/10,000 SSRIs: 32/10,000 Non-SSRIs: 29/10,000 Huybrechts, K. et al (2015). Antidepressant use late in pregnancy and risk of persistent pulmonary hypertension of the newborn. JAMA, 313(21), 2142-2151.
Odds Ratio 6.1 1.28 Huybrechts, K. et al (2015). Antidepressant use late in pregnancy and risk of persistent pulmonary hypertension of the newborn. JAMA, 313(21), 2142-2151.
Summary There is a potential risk of PPHN associated with maternal use of SSRIs in late pregnancy The overall risk might be more modest than previously described
