AU: Use is contraindicated.
UK: Use is not recommended during the first trimester and use is contraindicated during the second and third trimesters.
US: This drug should not be used during pregnancy unless there are no alternatives and the benefit outweighs the risk to the fetus.

AU TGA pregnancy category: D
US FDA pregnancy category: Not assigned

Risk Summary: Use of drugs that act on the renin angiotensin system (RAS) during the second and third trimesters of pregnancy increases fetal and neonatal morbidity and death.

Comments:
-Adequate methods of contraception should be encouraged.
-Advise pregnant women and females of reproductive potential of the potential risk to a fetus.

Animal studies have revealed evidence of fetotoxicity. In humans, exposure to angiotensin-converting enzyme (ACE) inhibitors during the second and third trimesters has revealed evidence of fetal and neonatal toxicity and fetolethality. There are no controlled data in human pregnancy.

AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. These drugs may also have adverse pharmacological effects. Accompanying texts should be consulted for further details.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.
