How can obstetrical providers possibly answer the pregnant woman who asks, ‘is this medication safe for me and my baby?’ when there is little information addressing that question?
Steve N. Caritis, MD

Research in Brief

Dr. Caritis is dedicated to answering a critical question: “Is this medication safe for me and my baby?” His work determines the right dosing during pregnancy—from statins and antidepressants to antibiotics—to protect both mother and child and reduce complications like preeclampsia and preterm birth. Recent focus is on effects of opioids on the fetus.
