Casodex and Breastfeeding
It is unclear if Casodex (bicalutamide) passes through breast milk. Casodex is not indicated for use in women for any reason, so any risks that may be posed to the nursing infant are unknown. It is also unclear if this prostate cancer medication would affect a woman's production of breast milk.
Casodex® (bicalutamide) is a prescription medication used to treat prostate cancer that has metastasized, or spread, to other areas of the body. It is considered an "antiandrogen" because it blocks the actions of androgens (male hormones) in the body.
Casodex is always used in combination with a gonadotropin-releasing hormone (GnRH) agonist, such as leuprolide (Eligard®, Lupron®, Lupron Depot®) or goserelin acetate implant (Zoladex®).
At this time, it is unknown if Casodex passes through breast milk. This medication is not approved for use in women. If you are nursing a child, talk with your healthcare provider prior to taking Casodex.
Casodex has not been studied in breastfeeding women, so it is unknown if the medication passes through breast milk. It is also unknown if the medicine would harm a nursing child or affect breast milk production.
However, Casodex is not approved for use in women, including women who are breastfeeding. It is only approved for use in men with prostate cancer.
You should discuss breastfeeding and Casodex with your healthcare provider. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision that is right for you.
