Abstract BACKGROUND : Maternal exposure to flu or fever has been associated with increased risk for neural tube defects (NTDs); however, few studies have considered the effects of medications on fever. We evaluated effect maternal fever, medication use (antibiotics, antipyretics), and their joint NTDs.
