Anxiety Meds Like Valium, Xanax Could Raise Miscarriage Risk

Pregnancy is often a time of heightened worry. But researchers warn that taking anti-anxiety drugs like Valium and Xanax may increase the risk of miscarriage.


Called benzodiazepines, these powerful drugs have long been prescribed to treat a variety of mood disorders. However, a new Canadian study finds that when taken in early pregnancy, they raise the risk for a miscarriage in the first trimester by 11%.

Medication use in pregnancy is a tricky business, experts say.

"In medications in pregnancy, physicians have to decide, are the risks higher than the benefits, because there isn't any risk zero," said lead researcher Anick Berard. She's a professor at the Centre Hospitalier Universitaire Sainte-Justine in Montreal.
