Cascara Sagrada

Summary of Use during Lactation

Maternal cascara intake might cause loose stools in some breastfed infants and should be avoided.[1] Other cathartics are preferred.

Drug Levels

After administration of 65 mg of cascara sagrada as cascara fluidextract, cascara was qualitatively detected in the breastmilk of 5 of 10 women collected over 20 hours.[2] The sensitivity of the assay was about 1100 mg/L of cascara.

Infant Levels. Relevant published information was not found as of the revision date.

Effects in Breastfed Infants

In 2 uncontrolled studies, a total of 10 of 22 breastfed neonates appeared to have loose stools after administration of 65 mg of cascara as cascara fluidextract to their mothers.[2]

In an observational case series, no cases of diarrhea were observed among the breastfed infants of 142 mothers who received 400 mg of cascara extract on day 3 postpartum.[3] This result might have been because of the small amount of colostrum received by the infants of this age.
