Benazepril 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: D
Comments: Adequate methods of contraception should be encouraged.
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 morbidity and death. There are no controlled data in human pregnancy.
US FDA pregnancy category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Benazepril Breastfeeding Warnings
Due to low levels of this drug in breastmilk, amounts ingested by the infant are small and would not be expected to cause any adverse effects.
Excreted into human milk: Yes (in small amounts)
Comments: The effects in the nursing infant are unknown.
One small study has reported that following 20 mg of this drug daily for 3 days to nursing mothers, nursing infants received less than 0.14% of the mother's weight-adjusted dose, mostly as the active metabolite.
