Breastfeeding and Antidepressants: What You Need to Know

When you're managing postpartum depression, a common but serious mood disorder that can start after childbirth and affect a mother’s ability to care for herself or her baby, the last thing you want is to choose between your mental health and your baby’s well-being. The good news? Many antidepressants while breastfeeding, medications used to treat depression that can pass into breast milk in small amounts are considered safe—and studies show they often help mothers bond better with their babies by improving their mood and energy.

Not all antidepressants are the same when it comes to breastfeeding. SSRI safety, the risk profile of selective serotonin reuptake inhibitors like sertraline and escitalopram during lactation is among the best studied. Sertraline, for example, shows up in breast milk in very low levels, and most babies show no side effects. In fact, many doctors recommend it as a first choice. On the other hand, some meds like paroxetine or fluoxetine may build up more in milk or in the baby’s system, so they’re used more carefully. The key isn’t avoiding meds altogether—it’s picking the right one for your body and your baby’s needs.

It’s not just about the drug—it’s about how your body handles it. Some moms notice a slight dip in milk supply, especially in the first few weeks. Others don’t notice anything. Your baby might be a little sleepier or fussier at first, but that usually fades. What matters most is watching for real signs: excessive drowsiness, poor feeding, or unusual crying. If you see those, talk to your doctor. Don’t stop your meds on your own—sudden withdrawal can make depression worse and hurt your recovery. Many moms find that combining meds with cognitive behavioral therapy, a proven psychological treatment that helps change negative thought patterns and behaviors gives them the best shot at feeling like themselves again—without sacrificing breastfeeding.

There’s no one-size-fits-all answer here. What works for one mom might not work for another. That’s why working with a doctor who understands both mental health and lactation is critical. You’re not choosing between being a good mom and being a healthy mom—you’re choosing the best path to be both.
