An Overview of Breastfeeding and Phenylephrine
It is unknown if
phenylephrine passes through breast milk. Therefore, if you are breastfeeding a child, talk with your healthcare provider before taking phenylephrine.
Is Taking Phenylephrine While Breastfeeding Safe?
No research has been done to see if phenylephrine passes through breast milk in humans. However, based on its chemical structure, phenylephrine probably does reach the breast milk.
In animal studies, phenylephrine (much like other decongestants) has been shown to decrease the supply of breast milk. This is probably not a problem for occasional doses (as the milk supply will recover) in women with a well-established milk supply. However, it may become a problem for women who take the medication frequently, are just starting to breastfeed, or are having milk supply problems.
If your healthcare provider decides that it is okay for you to take phenylephrine while breastfeeding, make sure to watch for irritability or any other problems in your child. If you notice a significant drop in your milk supply, it is probably best to avoid the medication.
Talking With Your Healthcare Provider
You should talk with your healthcare provider about breastfeeding and phenylephrine.
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.
