LactMed Database: Trusted Drug Safety Info for Breastfeeding Moms

When you're nursing, every pill, patch, or supplement feels like a risk. That’s where the LactMed database, a free, evidence-based resource from the National Library of Medicine that tracks how drugs pass into breast milk and affect infants. Also known as TOXNET LactMed, it’s the go-to tool for doctors, pharmacists, and moms who need clear answers—not guesses—about medication safety during breastfeeding. Unlike random blogs or forum advice, LactMed pulls data from real studies, clinical reports, and peer-reviewed journals. It doesn’t just say "safe" or "not safe." It tells you how much of the drug ends up in milk, when it peaks, how long it lasts in the baby’s system, and what side effects have been reported.

It’s not just about antidepressants or painkillers. LactMed covers everything: antibiotics for mastitis, thyroid meds, ADHD drugs like Adderall, even caffeine and herbal supplements. If it’s in your medicine cabinet, it’s likely in LactMed. And it’s updated regularly—no outdated warnings or half-truths. You’ll find entries for drugs like sertraline, ibuprofen, metformin, and even lesser-known ones like ethionamide (Trecator SC), with notes on infant monitoring and alternatives. It’s the same system hospitals use to approve prescriptions for nursing mothers.

What makes LactMed different? It doesn’t just list risks. It gives context. For example, it tells you that while caffeine passes into milk, most babies tolerate small amounts fine—unless mom drinks more than 5 cups a day. Or that certain antibiotics like penicillin are low-risk, while others like doxycycline need caution. It also links to alternatives when needed, helping you and your provider pick the safest option. You won’t find this level of detail in drug labels or pharmacy handouts. And you won’t find it in apps that sell supplements or push affiliate links. LactMed is pure, unbiased science.

Many moms worry about stopping meds during breastfeeding. But LactMed shows that in most cases, you don’t have to. With the right info, you can keep treating your condition—whether it’s depression, high blood pressure, or diabetes—without putting your baby at risk. The database even includes notes on timing doses to minimize exposure, like taking meds right after nursing. That’s the kind of practical, actionable insight you won’t get from a generic warning label.

Below, you’ll find real posts from moms and clinicians who’ve used LactMed to make smarter choices. From managing ADHD meds while nursing to understanding why some generics carry hidden risks, these articles tie directly to what LactMed tracks. Whether you’re just starting out or have been nursing for years, this collection gives you the tools to ask better questions, spot red flags, and trust the right sources.
