Intuniv and Breastfeeding

Intuniv (guanfacine ER) has been shown to pass through breast milk in rats, but it is still unknown if the drug passes through human breast milk. Because this product can decrease prolactin (a hormone that is important for breastfeeding), Intuniv could potentially make it harder for some women to produce enough breast milk.

Is Intuniv Safe for Breastfeeding Women?

Currently, it is unknown if Intuniv™ (guanfacine ER) passes through breast milk in humans. The manufacturer states that breastfeeding women should use this medication with caution. Therefore, if you are breastfeeding a child, you should talk with your healthcare provider before taking Intuniv.
 

Breastfeeding While Taking Intuniv: What Are the Concerns?

Because Intuniv passes through breast milk in rats, the medication is also expected to pass though breast milk in humans, although no research has been done to confirm this. It is not known what problems (if any) this drug could cause in a nursing infant.
 
Intuniv can decrease prolactin, a hormone that is important for breastfeeding. At least theoretically, the medication could decrease a woman's ability to nurse successfully and to produce enough milk. This most likely would be a concern for women just starting to breastfeed, and is unlikely to cause problems for an established breastfeeding relationship.
 

Talking With Your Healthcare Provider

You should talk with your healthcare provider about Intuniv and breastfeeding. 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.
