ACOG the parent organization of obstetricians and gynecologists re-affirms that acetaminophen as one of the only safe pain reliever medication to use during pregnancy. They put out a statement saying there are no studies that proves a direct relationship between normal, infrequent, careful use of acetaminophen during any trimester and fetal medical or developmental problems.
A recent article in the journal Nature Reviews Endocrinology claimed that acetaminophen, may alter fetal development and increase risk for a developing fetus.
Neurodevelopmental disorders, the ACOG statement says in particular, are “multifactorial and very difficult to associate with a singular cause. The brain does not stop developing until at least 15 months of age [after birth], which leaves room for children to be exposed to a number of factors that could potentially lead to these issues.”
The healthiest way to use medication in pregnancy is for you and the baby’s dad to use contraception until you plan to get pregnant, have a pregnancy planning visit, begin prenatal care early, and any medication actually used during pregnancy should be used only as needed, in moderation, and after the pregnant patient has consulted with their doctor.
