Antidepressants While Breastfeeding

When you're nursing and struggling with postpartum depression, the question isn't just antidepressants while breastfeeding—it's can I do this without risking my baby’s health? Many moms feel torn: they need relief, but they also fear harm. The good news? Not all antidepressants pass into breast milk in harmful amounts. Some, like sertraline and paroxetine, are among the most studied and are often recommended by pediatricians and psychiatrists because they show up in breast milk at very low levels. These are not just theoretical choices—they’re used daily by thousands of nursing mothers with no reported harm to infants in large-scale studies.

It’s not about avoiding medication altogether. It’s about choosing wisely. SSRIs, a class of antidepressants that include sertraline, fluoxetine, and escitalopram, are the most commonly prescribed because they have the best safety profile for breastfeeding. Postpartum depression, a serious mood disorder that affects up to 1 in 7 new mothers doesn’t go away on its own, and untreated depression can impact bonding, feeding, and even your baby’s development. Your mental health isn’t separate from your baby’s well-being—it’s part of it. That’s why doctors often encourage treatment over silence. Some moms worry about side effects like drowsiness or fussiness in their babies, but these are rare and usually mild. The bigger risk? Staying untreated.

Not all antidepressants are equal here. Fluoxetine stays in your system longer and can build up in breast milk, so it’s often avoided unless absolutely necessary. Bupropion and SNRIs like venlafaxine are used too, but with more caution and closer monitoring. What matters most isn’t the drug name—it’s the dose, your individual metabolism, and how your baby reacts. Most babies show no signs at all. If you’re on medication and nursing, your doctor should track both your mood and your baby’s sleep, feeding, and weight gain. There’s no one-size-fits-all answer, but there is plenty of real-world data to guide you.
