Prostate Cancer Home > Flutamide and Breastfeeding

The effects of flutamide (Eulexin) on a breastfeeding woman and her infant are unknown. For one thing, the medication has not been studied in breastfeeding women. In addition, the drug is approved for use in men only and would not typically be prescribed for a woman, nursing or not. Women who are taking flutamide "off-label" should discuss this issue with their healthcare provider.

Is Flutamide Safe While Breastfeeding?

Flutamide (Eulexin®) is a prescription medication used in the treatment of prostate cancer. It works by blocking the effects of male hormones, such as testosterone (called androgens). Flutamide is used with a medicine that decreases the production of testosterone in the body. The combined action of these two medicines slows down the growth of prostate cancer cells, which depend on testosterone to grow.
At this time, it is unknown if flutamide passes through breast milk. However, the medicine is not approved for use in women, although it may be prescribed "off-label" for a woman to treat hirsutism (excessive hair growth). Therefore, if you are nursing a child, talk with your healthcare provider prior to taking this medication.

More Information on Breastfeeding and Flutamide

No research has been done to see if flutamide passes through breast milk. This is because flutamide is not approved for use in women. Also, medications are rarely studied in breastfeeding women, as this would usually expose an infant, who will not directly benefit from the medication, to possible side effects.

Talking With Your Healthcare Provider

You should discuss breastfeeding and flutamide 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.
