Anti-HIV drug use during pregnancy does not affect infant size, birth weight

NIH study indicates drug safe during pregnancy, but infants smaller at first birthday

Infants born to women who used the anti-HIV drug tenofovir as part of an anti-HIV drug regimen during pregnancy do not weigh less at birth and are not of shorter length than infants born to women who used anti-HIV drug regimens that do not include tenofovir during pregnancy, according to findings from a National Institutes of Health network study. However, at 1 year of age, children born to the tenofovir-treated mothers were slightly shorter and had slightly smaller head circumference β€” about 1 centimeter each, on average β€” than were infants whose mothers did not take tenofovir.
