Breastfeeding and Medications: Practical Safety Tips You Can Use Today
Worried a medicine will harm your baby? Good—asking questions is the best first step. This page gives straight, practical steps for checking drugs, supplements, and online pharmacies while you breastfeed. No panic, just useful moves you can make right away.
How to check a medicine fast
Start by writing down the exact drug name and dose (active ingredient, not just brand). Search LactMed (a free U.S. database with study summaries), and look for clear statements about infant exposure and any reported effects. If LactMed isn’t available, ask your prescriber or a pharmacist and request a safer alternative if needed. Topical creams and eye drops usually have much lower transfer to milk than pills or injections, but always verify—"topical" isn't a free pass.
If you ordered the medicine online, confirm the pharmacy is licensed. Look for an actual address, a pharmacist contact, and approval seals such as NABP or CIPA. Our site has a full guide on checking online pharmacy credentials—use it before you buy. Never skip a prescription requirement: legit pharmacies will ask for one.
Simple safety rules that work
Use the lowest effective dose for the shortest time. If a drug has a known safer alternative in breastfeeding, ask your doctor to switch. Time doses when possible: taking a medicine right after a feeding often gives the longest drug-free interval before the next feed. Remember, "pump and dump" doesn’t speed drug clearance—time does. Only pump and discard if advised (for example, certain chemotherapies or specific poisons).
Choose OTC pain meds carefully: acetaminophen and ibuprofen are commonly recommended for short-term use while breastfeeding, but check with a clinician if you need frequent or high-dose therapy. Be cautious with herbal supplements—many lack safety data for babies. When antibiotics are needed, many are safe; ask about specific choices if you’re concerned.
Watch your baby for warning signs after you start a new medicine: unusual sleepiness, difficulty feeding, rash, breathing changes, or persistent vomiting. If any of these appear, contact your pediatrician or local emergency services. Keep a list of medicines you take and share it at pediatric visits—this makes spotting interactions and side effects faster.
Finally, store and label pumped milk clearly, and follow safe-handling guidelines. If you buy medication from another country or an online vendor, double-check the active ingredient and dose—brands and names vary. When in doubt, trade a quick message with your prescriber or pharmacist: a two-minute question can prevent a lot of worry.
Despite being banned in the U.S. and not approved as a lactation aid anywhere in the world, domperidone is widely used by nursing mothers, especially in Canada, to stimulate milk production. Health Canada acknowledges risks like heart issues and debilitating psychological effects, but the drug remains popular due to its perceived effectiveness. Ongoing debates call for thorough research into its safety for lactation purposes.
