SUTENT and Breastfeeding
It is unclear if SUTENT (sunitinib) passes through human breast milk. However, the medication has been shown to pass through the breast milk of rats, and it is likely that it would also pass through human breast milk. It is generally recommended to avoid breastfeeding while taking SUTENT. If your doctor says it is okay to breastfeed, monitor your child for diarrhea and other side effects.
SUTENT® (sunitinib) is a prescription medication approved for the treatment of certain types of kidney, pancreatic, and gastrointestinal (GI) cancer. It is unknown if this medication passes through breast milk in humans. If you are currently breastfeeding a child, talk to your healthcare provider before taking SUTENT.
There are no adequate studies of SUTENT use during breastfeeding, and no reports of breastfeeding women using the medicine. Therefore, it is unknown if the medication passes through human breast milk, or if it would harm a nursing child.
In animal studies, the drug was shown to pass through the breast milk of rats. Based on the properties of the medicine, it is also expected to pass through human breast milk.
SUTENT is associated with potentially serious side effects that could harm a nursing infant exposed to the drug. Therefore, it is generally not recommended for use in women who are nursing. However, if your healthcare provider recommends SUTENT while breastfeeding, be sure to observe your child closely. Contact your child's healthcare provider if you notice any possible side effects, such as:
- Excessive or unusual crying
- Anything else that doesn't seem right.
