However, data on maternal and foetal safety following gestational exposure are lacking. The aim was to examine whether first trimester exposure to papaverine is associated with increased risk for major malformation and whether gestational exposure at any stage is associated with increased risk for preterm delivery, lower birthweight, small for gestational age, caesarean section (CS), lower Apgar score and perinatal death.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective comparative study consisted of pregnant women treated with papaverine between February 2010 and October 2019 at a large tertiary center.

Rate of major malformations did not differ between study group (2\/46, 4.3%) and control (25\/315, 4.9%, <jats:italic>P =<\/jats:italic>\u00a0.67).
