Benzodiazepine and risk of ectopic pregnancy

A study in Human Reproduction shows an association with use of Benzodiazepine (more commonly known as Valium and Xanax) and ectopic pregnancy.

While the association is interesting, the EPT strongly suggests that the study be interpreted with caution. The study is not designed to show precise cause and there may be many reasons why women who have been prescribed with the drug might have higher incidence of ectopic pregnancy. In other words, the increased incidence of ectopic pregnancy may not be directly linked to use of the drug.

As a causal link has not been shown, more research is needed and, accordingly, women should not change medication prescribed by their doctor.
