Conditions in Pregnancy: Use of ACE inhibitors
Motherisk research in 2011 found that the use of ACE inhibitors to treat hypertension during the first trimester of pregnancy may be associated with a higher risk of miscarriage.
Angiotensin converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) are known to cause fetal renal damage in pregnancy. Due to conflicting reports in the literature, their safety after first trimester exposure has been debated. Our aim was to determine whether the use of ACE inhibitors or ARBs in the first trimester of pregnancy is associated with an increased risk for major malformations or other adverse outcomes. Motherisk's study results suggest that ACE inhibitors/ARBs are not major human teratogens; however, they may be associated with an increased risk for miscarriage.
