Benazepril / hydrochlorothiazide Pregnancy Warnings

This drug should not be used during pregnancy unless there are no alternatives and the benefit outweighs the risk to the fetus.

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 failed to reveal evidence of teratogenicity. In humans, use of drugs that act on the renin angiotensin system during the second and third trimesters increases fetal and neonatal toxicity and death. There are no controlled data in human pregnancy.

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.
