Prostate Cancer Home > Emcyt and Breastfeeding
It is not clear whether Emcyt (estramustine) would pass through breast milk in women or if it would harm a nursing infant. However, this drug is not approved for use in women and would not likely be prescribed for women who are breastfeeding. Emcyt is only approved to treat prostate cancer in men.
Can Breastfeeding Women Take Emcyt?
At this time, it is unknown if Emcyt® (estramustine phosphate) passes through human breast milk. However, this drug is only approved to treat prostate cancer, and therefore is only used in men. If you are nursing a child, talk with your healthcare provider before taking Emcyt.More Information on Breastfeeding and Emcyt
There is very little information available about using Emcyt while breastfeeding. The drug has not been studied in women who were nursing or in breastfeeding animals. Therefore, it is unknown if the medication passes through breast milk or if it would harm a nursing child.Emcyt is a medicine that combines estradiol, a female hormone, with a chemotherapy medicine known as nornitrogen mustard. Estradiol passes through breast milk in small amounts. Although the amounts of estradiol found in breast milk are generally too low to cause any significant problems in a nursing infant, the medication may decrease the production and quality of breast milk.
There is even less information available on the chemotherapy drug portion of Emcyt. However, in general, nitrogen mustards are considered toxic, and should usually be avoided while breastfeeding.
Perhaps more importantly, Emcyt is not approved for use in women. At this time, there is no well-accepted medical reason for a woman to take this drug.
