A large epidemiological study from the United States on statin use in the first trimester of pregnancy has found no evidence of a teratogenic effect. However, the study authors concluded that further research is needed before statins can be considered safe in pregnancy. Although this study provides reassurance about the use of statins in pregnancy, as with any observational study, it was open to bias and its findings offer guidance rather than proof. It seems reasonable to continue advising women not to conceive while taking statins especially as more subtle neurodevelopmental and infant behaviour effects were not addressed.
