A caregiver at a distribution site says she was put on an antibiotic after cutting her leg in the flood, and was told to stop nursing for a week. She wants to know whether that is true.
That is a clinical question, and it is not ours to answer. What we can do — and what this page is for — is make sure the people who can answer it have the right reference in front of them, and that the parent knows where to look for herself.
What LactMed is
LactMed is the National Institutes of Health database of drugs and other chemicals a breastfeeding parent might be exposed to. For each substance it gives the levels found in human milk and in infant blood, the possible effects on a nursing infant, and suggested alternatives where one exists. Everything in it comes from published literature, is fully referenced, and is reviewed by a panel for scientific validity.
It is free, needs no account, and works in a phone browser.
How we actually use it
Two ways, and both of them keep us in our lane.
- We hand it to prescribers and pharmacists. This is the main use. A clinician working a twelve-hour shift in a disaster is making fast calls with incomplete information, and “stop breastfeeding” is the fast, safe-sounding call. Passing along a link to the NIH database is a collegial act, not a challenge — most clinicians are glad to have it, and pharmacists in particular are often the most reachable clinician in a response.
- We point parents to it. A parent is entitled to read the evidence about her own body and her own baby, and helping her find a public NIH resource is education, not advice. What she does with it is between her and her provider.
We educate. We do not practice medicine. Nobody on a SAFE team tells a family to start, stop, or change a medication — that is the prescriber’s decision and it stays theirs.
Why this comes up more in a disaster
After a disaster, people who were not on any medication two weeks ago suddenly are. Tetanus boosters after wounds. Antibiotics after exposure to contaminated water. Something for pain after an injury. Something for sleep or anxiety when the shelter never gets dark or quiet. Each one is a fresh opportunity for somebody to be told, quickly and without checking, to stop breastfeeding.
In ordinary times that advice is usually just wrong and costly. In a disaster it can be dangerous, because stopping means starting formula — and formula means safe water, clean equipment, fuel and storage, in exactly the conditions where none of those can be relied on. An unnecessary interruption to breastfeeding is not a neutral event when the alternative infrastructure is broken.
A sentence that stays inside anyone’s scope
If you take one thing from this page, take this. It works whether you are an IBCLC or a volunteer who signed up last week:
“There’s a free NIH database called LactMed that covers medications and breastfeeding. Would it help if I sent you the link, so you can take it back to your pharmacist or your doctor before you stop?”
That sentence gives information, names the decision-maker, and asks permission. It does not diagnose, advise or contradict anyone.
If your team has not yet written down where each volunteer’s scope ends, this is the question that will force the issue — volunteers on an IYCF-E team range from clinicians to laypeople, and they need to know before they are standing in front of the family, not after.
