NSAIDs Breastfeeding Safety: Quick Guide for Nursing Moms

If you’re feeding your baby and need a pain reliever, the first question is usually “Is this safe?” NSAIDs – non‑steroidal anti‑inflammatory drugs – are common over‑the‑counter meds like ibuprofen, naproxen, and aspirin. Most of them pass into breast milk in tiny amounts, but some are safer than others. Below you’ll get the basics you need to decide what’s okay for you and your baby.

Common NSAIDs and Their Breast Milk Levels

Ibuprofen (Advil, Motrin) is the go‑to choice for most nursing moms. Studies show only about 0.01% of the dose ends up in milk, which means it’s considered low risk. A single 200‑400 mg dose is fine; you can repeat it every 6–8 hours if needed.

Naproxen (Aleve) has a slightly higher milk level – roughly 0.02% of the dose – but it’s still within safe limits for short‑term use. Stick to the recommended 220 mg dose and don’t exceed two tablets per day.

Aspirin is a special case. Low‑dose aspirin (81 mg) used for heart protection is generally okay, but regular adult doses (325 mg or more) can increase bleeding risk for the baby. Most doctors advise nursing moms to avoid regular‑strength aspirin unless prescribed.

Ketoprofen and Diclofenac are less common in the U.S., and data on milk transfer is limited. Because of the uncertainty, it’s safer to choose ibuprofen or naproxen instead.

Tips for Safe Use While Nursing

1. Take the lowest effective dose. You don’t need a huge amount to ease a headache or sore muscles. Start with the smallest tablet that works.

2. Time your doses right after nursing. This gives your body time to clear the drug before the next feeding, keeping milk levels low.

3. Avoid long‑term daily use. If you find yourself needing NSAIDs every day for weeks, talk to your doctor about alternative treatments or a short break from breastfeeding while you recover.

4. Watch for side effects in baby. Rarely, babies might show unusual sleepiness or rash. If that happens, stop the medication and call your pediatrician.

5. Stay hydrated. NSAIDs can irritate your stomach, especially on an empty tummy. Have a glass of water or a light snack with each dose.

Remember, every mom’s situation is different. If you have any health conditions – like kidney disease or ulcers – the safety profile changes and you should get personalized advice from a healthcare provider.

Bottom line: ibuprofen is the safest bet for short‑term pain relief while nursing, naproxen works too if you need longer coverage, and regular aspirin should be avoided. Use the smallest dose you need, take it right after feeding, and keep an eye on your baby’s reaction. With these simple steps you can manage headaches, muscle aches, or fever without worrying about harming your little one.
