Taking Benadryl while breastfeeding is usually considered safe in normal doses, but there's a catch: Benadryl, or diphenhydramine, is an antihistamine, and while it's generally fine for treating those pesky allergy symptoms, it can pass into your breast milk.
Research, including a study from the Journal of Human Lactation2 , suggests that occasional use of Benadryl doesn't typically cause issues for your little one. However, some experts suggest that certain antihistamines could potentially decrease milk supply, especially with regular or high-dose use.
It's also worth noting that Benadryl can cause drowsiness in both you and potentially your baby. And we all know a sleepy baby might not nurse as effectively, which could also impact your milk supply.
That's why it's best to have a chat with your healthcare provider before taking Benadryl or any other medication while breastfeeding.
