Can I Breastfeed While Sick or on Antibiotics?

Welcome to 2026 - we're in the thick of winter! Being a new parent is hard enough without having to worry about whether your illness or medication could affect your baby. A common question is: “Can I keep breastfeeding if I’m sick or taking antibiotics?” Let’s break it down in simple terms.

Breastfeeding While Sick

Good news: in most cases, it’s safe to breastfeed when you’re sick. In fact, breastfeeding can actually help your baby! When you’re sick, your body produces antibodies that pass through your milk, giving your baby some extra protection.

Common illnesses:

• Colds and flu
• Mild stomach bugs
• Respiratory infections

These usually aren’t a reason to stop breastfeeding. Just make sure to wash your hands often, cover your mouth when coughing or sneezing, and consider wearing a mask if you have a contagious respiratory illness.

Breastfeeding While on Antibiotics

Many new parents worry that taking medication, especially antibiotics, could harm their baby. Most antibiotics are safe for breastfeeding, but it depends on the type, dose, and how long you need to take them.

Tips:

• Always tell your doctor or pharmacist that you are breastfeeding as they can choose the safest option.
• Watch your baby for signs of digestive upset (diarrhea, rash, or fussiness), which are rare but possible.
• If your antibiotic isn’t safe for breastfeeding, your doctor may switch you to one that is.

Quick note: Antibiotics do not require you to stop breastfeeding in most cases. Pumping and discarding milk (“pump and dump”) is usually only necessary for a few specific medications, not most antibiotics.

Practical Tips to Stay Healthy and Keep Feeding

1. Hydrate and rest: being sick can lower your energy, so drink plenty of fluids and rest when you can.
2. Wash your hands often: this helps prevent spreading germs to your baby.
3. Take medicine as prescribed: don’t skip doses; finishing your antibiotic course is important.
4. Watch your baby: a few minor changes may happen, but significant reactions are rare.

Bottom Line

Being sick or taking antibiotics usually does not mean you have to stop breastfeeding. Your milk continues to provide nutrition and antibodies to your baby, and most medications are compatible with breastfeeding. Always check with your healthcare provider to choose the safest treatment, and remember: breastfeeding while sick is not only safe—it can help your baby’s immune system too.
