Are Medications Safe While Breastfeeding? How to Know What’s Compatible with Lactation
If you’re breastfeeding and need to take medication — whether it’s for a cold, chronic condition, or something more serious — you’re not alone in wondering: Is this safe for my baby?
The good news? Most medications are compatible with breastfeeding. But navigating the information can feel overwhelming, especially when you see warnings on prescription labels or conflicting advice online. Let’s break it down so you can make informed, confident choices.
Why Medication Safety Matters in Lactation
When you’re nursing, small amounts of medication can pass into your breast milk — but that doesn’t automatically mean it’s harmful. What matters is how much passes through, how it might affect your baby, and there are safer alternatives if needed.
Common Myths
“If I’m taking any medication, I have to stop breastfeeding.”
False. Many medications are safe to use while nursing, and stopping breastfeeding can sometimes carry more risk than continuing.“There’s no data, so it must not be safe.”
Actually, we have more research now than ever before — and expert resources to guide decisions.
What to Consider
When evaluating a medication’s safety while breastfeeding, professionals look at:
How much of the drug passes into milk
The age and health of the baby (newborns process medications differently than older infants)
How long the medication stays in your system
The potential for side effects in the infant
Where to Find Reliable Information
Here are trusted resources you (and your healthcare providers) can use:
LactMed: A free database from the U.S. National Library of Medicine
https://www.ncbi.nlm.nih.gov/books/NBK501922/InfantRisk Center: Research-based info from Texas Tech University
https://www.infantrisk.comE-lactancia: A helpful Spanish/English site that categorizes risk levels

Talk to the Right Professionals
Many prescribers are cautious — sometimes overly so — simply because they don’t specialize in lactation. If you’re unsure, speak with:
A lactation consultant trained in pharmacology (IBCLC)
A pediatrician or family doctor familiar with breastfeeding
Or call the InfantRisk Center directly for guidance
Final Thoughts
You shouldn’t have to choose between your health and breastfeeding. With the right support and information, you can often do both safely. Always advocate for yourself — and don’t hesitate to ask your care team to consult lactation-specific resources before recommending you wean or “pump and dump.”
Your health matters, and so does your baby’s. With the right tools, you can protect both.
