Pregnancy Over 40, Possible Cause Of Birth Defects: AntibioticsSome antibiotics are necessary for pregnant women, however, there are certain categories which should be avoided to prevent birth defects.
Sulfonamides and nitrofurantoins could cause problems for your unborn baby. Of course, talk with both your doctor and pharmacist before taking anything in pregnancy.
Antibacterial use among all women increased during pregnancy, peaking during the third month. A total of 3,863 mothers of children with birth defects (29.4 percent) and 1,467 control mothers (29.7 percent) used antibacterials sometime between three months before pregnancy and the end of pregnancy.
Two medications -- sulfonamides and nitrofurantoins (each used by 1.1 percent of cases and 0.9 percent of controls) -- were associated with several birth defects, suggesting that additional study is needed before they can be safely prescribed to pregnant women.
