Breastfeeding and Medications:
Many medications are compatible with human milk feeding, but it’s always wise to check before starting any new prescription or over-the-counter drug. The way a medication affects a breastfed baby depends on several factors, including the baby’s age, the dose the parent is taking, and how the body metabolizes the drug.
Key Points to Know:
Most common medications (like antibiotics, pain relievers, antidepressants, and birth control) have been studied in lactating parents and are often compatible with breastfeeding.
Premature or medically fragile babies may be more sensitive to medications in breast milk.
Timing matters: In some cases, taking a medication right after nursing or before a long sleep stretch may minimize exposure to the baby.
Herbal supplements and over-the-counter medications should also be checked for safety.
