Prevacid naprapac Pregnancy Warnings
Lansoprazole-naproxen has been assigned to pregnancy category C by the FDA. Animal studies have failed to reveal evidence of fetal harm. There are no controlled data in human pregnancy. Naproxen use in late in pregnancy may cause premature closure of the ductus arteriosus and prolong labor and delivery. Lansoprazole-naproxen is only recommended during pregnancy when there is no alternative and benefits outweigh risks.
