Cohen JM, et al. - The authors sought to assess whether psychostimulants used to treat attention-deficit/hyperactivity disorder (ADHD) were associated with risk of adverse placental-associated pregnancy outcomes including preeclampsia, placental abruption, growth restriction, and preterm birth. They observed a small increased relative risk of preeclampsia and preterm birth in association with psychostimulant use during pregnancy. Given the small absolute increases in the risks, women with significant ADHD should not be counseled to suspend their ADHD treatment based on these findings.
