Cenestin and Breastfeeding

Studies on Cenestin and breastfeeding have shown that the hormones in this medication do pass through breast milk in low amounts. Although these amounts are probably too low to cause significant problems in a nursing infant, they may decrease the quantity and quality of breast milk. Therefore, it is typically recommended that women avoid Cenestin while breastfeeding.

 

Is Cenestin During Breastfeeding Safe?

Cenestin® (conjugated estrogens) is a prescription medication that is approved to treat menopausal symptoms, including hot flashes and vaginal dryness. The estrogen hormones in Cenestin can pass through breast milk and may decrease the quality and quantity of breast milk. Therefore, make sure to check with your healthcare provider before taking Cenestin if you are breastfeeding (or planning to breastfeed).
 

What Does the Research Say About Cenestin and Breastfeeding?

Research suggests that the estrogen hormones in Cenestin pass through breast milk. However, the low amounts of the hormones that pass through breast milk are probably too low to cause significant or long-lasting problems in breastfed infants.
 
More importantly, the estrogen hormones in Cenestin may decrease the production and quality of breast milk. It is for this reason that estrogen-containing medications (including Cenestin, other hormone replacement medications, and many birth control pills) are not usually recommended for women who are breastfeeding.
