How to Handle Cold and Flu Season During Pregnancy
By Dr. Stephen Cole, Obstetrician
As the temperature drops, we see more runny noses, scratchy throats, and body aches—signs that cold and flu season is here. If you're pregnant, this time of year can feel especially challenging. Your immune system is naturally dialled down to support your growing baby, but that also makes it easier to catch viruses and harder to shake them off. You are also more prone to the severe effects of infections like influenza.
Here’s what you need to know to stay safe, comfortable, and healthy through the season.
Why Pregnancy Makes You More Vulnerable
Pregnancy changes your immune system. It becomes slightly suppressed so your body doesn’t see your baby as a threat. This is completely normal, but it does mean you’re more prone to infections like the common cold or influenza.
For most people, a cold is just inconvenient. But during pregnancy, a high fever or lingering cough can have more serious effects, especially in early pregnancy or later stages when your lungs are already working overtime.
What’s Safe to Take—and What’s Not
If you come down with symptoms, the first instinct is to reach for the medicine cabinet. But not everything is safe in pregnancy.
Generally safe options include:
-
Paracetamol (Panadol): Safe for headaches, fever, and mild aches.
-
Saline nasal sprays: Helpful for congestion.
-
Lozenges or honey and lemon tea: Good for sore throats.
Avoid or check with your doctor before taking:
-
Decongestants like pseudoephedrine (especially in the first trimester).
-
Ibuprofen (Nurofen), and other non-steroidal anti-inflammatories.
-
Certain cough syrups and herbal remedies.
Always check with your GP, pharmacist, or obstetrician before taking any medication, even those marked "natural."
When to Call Your Doctor
Most colds are self-limiting, but sometimes it's more than “just a virus.” Get in touch with your doctor if you experience:
-
A fever above 38.5°C that doesn’t respond to paracetamol.
-
Difficulty breathing or chest pain.
-
Severe coughing that affects your ability to sleep or eat.
-
Decreased baby movement.
-
A cold that’s not improving after 5–7 days.
Don’t feel like you’re being a bother—better safe than sorry.
Natural Remedies That Actually Help
Here are some simple, pregnancy-safe ways to ease symptoms:
-
Rest: Your body is already working hard—now it needs extra support.
-
Hydration: Warm fluids soothe sore throats and thin mucus.
-
Steam inhalation or a warm shower: Great for clearing blocked noses.
-
Honey and lemon: Soothes irritated throats and helps coughs.
Skip unproven remedies or "immune boosters" unless your doctor approves them.
Preventing Colds and Flu
Prevention is always better than cure. Here’s how to reduce your risk:
-
Get the flu vaccine. It’s safe in any trimester and offers protection for both you and your baby after birth. I recommend that all pregnant women have a flu vaccine.
-
Wash hands frequently. Simple but effective.
-
Avoid close contact with sick people. Politely step back or ask others to reschedule visits.
-
Keep your surroundings clean. Wipe down shared surfaces regularly.
Final Word
Getting sick while pregnant can feel overwhelming, but most colds and flus pass without harm. The key is knowing what’s safe, when to treat, and when to call your doctor.
If you're ever unsure, please don’t hesitate to reach out. That’s exactly what we’re here for.
Stay warm, stay well—and take care of yourself and your baby this season.
