Allergies can be quite common in spring and summer months. If you suffer from allergies you may be wondering what medications, if any, you can take while breastfeeding. There are many medications over the counter and prescriptions that are available for allergy relief. Most antihistamines, when taken in moderation have very few, if any, side effects for the nursing baby. But before taking any medication PLEASE discuss them with your baby’s pediatrician first! If you choose to take an antihistamine, you could possibly see a decrease in your milk supply.
