What effect may Benadryl have on breast milk production?

What effect may Benadryl have on breast milk production?

• A. Increases prolactin and milk production
• B. Reduces prolactin levels and milk production
• C. No effect on prolactin or milk production
• D. Causes galactorrhea in all breastfed infants

Answer: (B)

Prolactin drives milk production, so anything that lowers prolactin can reduce milk supply. Benadryl (diphenhydramine) is a sedating first‑generation antihistamine that, in some individuals, can influence the hypothalamic–pituitary axis and dampen prolactin release. That potential reduction in prolactin can lead to decreased milk production, which is why this option fits as a possible effect. It doesn’t reliably increase prolactin or milk production, and it isn’t accurate to say it causes galactorrhea in all breastfed infants. In practice, Benadryl is usually considered compatible with breastfeeding, but it’s not a method to boost milk supply.
