Kidneys Home > NULOJIX and Breastfeeding

No research has been done to determine if NULOJIX (belatacept) passes through human breast milk. However, it has been shown to pass through the breast milk of rats and may cause potentially dangerous and even life-threatening side effects. Therefore, the manufacturer of the drug recommends that women not use NULOJIX while breastfeeding.

Can Breastfeeding Women Receive NULOJIX?

NULOJIX® (belatacept) is a prescription medication approved for the prevention of transplant rejection in people who receive a kidney transplant. Transplant rejection occurs when the body recognizes the transplanted organ as foreign and attacks it. NULOJIX is used in combination with other medications. It is given as an injection into a vein (known as an intravenous, or IV, injection).
At this time, it is unknown if NULOJIX passes through breast milk. The manufacturer of the medication recommends that women not use it while breastfeeding.

More Information on NULOJIX and Breastfeeding

There is currently no information available on the use of NULOJIX during breastfeeding in humans. In animal studies, NULOJIX was shown to pass through the breast milk of rats. However, NULOJIX has not been studied in breastfeeding women. Therefore, it is unknown if the drug passes through human breast milk, or if it would harm a nursing infant.
NULOJIX is associated with serious side effects, including the risk for potentially life-threatening infections. Because of the potential for such side effects in a nursing child, it may be best to avoid breastfeeding while using NULOJIX.

Talking With Your Healthcare Provider

You should discuss breastfeeding and NULOJIX 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.
