Lupron and Breastfeeding
Women may not be able to safely use Lupron (leuprolide) while breastfeeding. Although no research has been done to determine whether this drug passes through breast milk, the manufacturer of the drug recommends that women not use Lupron while nursing. This medication might affect breast milk production, and there may be potential risks to a nursing infant.
Lupron® (leuprolide acetate) is a prescription medication used to treat the symptoms of prostate cancer. It is also used to treat early-onset puberty, known medically as precocious puberty, in children.
It is unknown if Lupron passes through breast milk. The manufacturer of the medication recommends that women not use Lupron while breastfeeding.
No research has been done to see if Lupron passes through breast milk. It is also unknown if Lupron has any effects on breast milk production or on a nursing child. While this lack of information is certainly frustrating, it is important to understand that medications are rarely studied in women who are breastfeeding, as this would usually expose an infant who will not directly benefit from the medication to possible risks.
Lupron is not active when taken orally (this is why it must be given by injection). Therefore, it would be unlikely to cause problems if consumed by a nursing infant through breast milk.
However, Lupron is a synthetic (manufactured) form of a hormone that helps stimulate the production of sex hormones. Therefore, it could potentially affect breast milk production. Breastfeeding is not recommended during Lupron treatment.
You should discuss breastfeeding and Lupron use 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.
