Certain Antibiotics May Increase Risk of Birth Defects

July 2017

A large study published in the British Journal of Clinical Pharmacology found that certain antibiotics taken during pregnancy may increase the risk for birth defects.

Canadian researchers followed 139,938 mothers of babies born in Quebec from 1998 to 2008, tracking their antibiotic use in the first trimester, and their babies’ birth defects through the first year of life. The senior author, Anick Bérard, a professor of epidemiology at the University of Montreal, said that antibiotics in the class called quinolones – ciprofloxacin, levofloxacin and others – are particularly dangerous and should be avoided in pregnancy.

But she said: “Infection itself is associated with adverse pregnancy outcomes, and they must be treated. Our study shows that we must think about which antibiotics to use.”
