There is evidence of risk to fetus in human studies, but the potential benefits of Olmesartan may warrant the usage despite the risks. It is recommended to change to alternative antihypertensives with established safety profile in pregnancy, unless angiotensin receptor blocker (ARB) therapy is indicated in women planning for pregnancy. It has been demonstrated that exposure to ARB during the second and third trimesters may induce fetotoxicity and neonatal toxicity.
