It’s generally recommended to avoid phenylephrine while breastfeeding.
Phenylephrine is a common ingredient in over-the-counter cold and allergy medications, often used to relieve nasal congestion. However, according to a study in the Journal of Human Lactation1 , phenylephrine might decrease the production of breast milk.
Additionally, the American Academy of Pediatrics recommends caution when using phenylephrine during breastfeeding, as its effects on breastfeeding aren't well-studied. While it may be effective in relieving congestion, safety for the nursing infant isn't fully established.
Therefore, while breastfeeding, it's best to avoid using phenylephrine if possible. As always, it's important to consult with your healthcare provider for guidance on suitable alternatives that won't affect your milk supply or potentially impact your baby's health.
