The Flu in Pregnancy: Symptoms, Risks & How to Protect Yourself

Flu While Pregnant: What You Need to Know to Protect Yourself and Your Baby

Getting influenza, often referred to as the flu, while pregnant can be more serious than for non-pregnant adults, but most cases are manageable with prompt care. Pregnant people face higher risks due to changes in immunity, heart, and lung function. 

This guide covers symptoms, risks, treatment options, and the importance of the flu vaccine. It also provides clear steps to protect both you and your baby while reassuring you that help is available if you get sick.

Why the Flu Matters More During Pregnancy

Pregnancy naturally alters the immune system, making it harder to fight infections. The heart and lungs also work harder, increasing vulnerability to complications if influenza strikes. Studies in Australia show pregnant people are more likely to require hospital care for the flu compared with non-pregnant adults. Complications can include dehydration, pneumonia, and in some cases, preterm birth. Staying informed and proactive is key to reducing risks for you and your baby.

The Flu vaccination is recommended in all pregnant women to prevent infection.

Flu Symptoms to Watch For When Pregnant

Flu symptoms often appear suddenly and can be more intense than a common cold. Watch for:

• Fever and chills

• Cough and sore throat

• Body aches and fatigue

• Nasal congestion

• Headache

Symptoms may overlap with a cold or COVID-19, but high fever and rapid onset are more typical of the flu. Early recognition is crucial, contact your GP promptly if symptoms appear, especially if you have a high fever or difficulty breathing.

Tip: Keep track of symptoms and contact a GP early if unsure.

When to See a Doctor

Seek medical attention promptly if you experience persistent fever, trouble breathing, severe fatigue, or signs of dehydration such as dizziness, dry mouth, or reduced urine. Early consultation with your GP is especially important in later trimesters, as pregnancy increases vulnerability to complications. Don’t wait for symptoms to worsen, timely care can prevent serious outcomes for both you and your baby.

Can the Flu Affect My Baby?

Yes, the flu can potentially impact your baby, particularly if left untreated. High fever in pregnancy has been linked to a slightly higher risk of complications, including preterm birth. 

The good news is that with prompt care, rest, hydration, and medical guidance, most pregnancies continue safely. The Flu vaccination is a safe and effective way to protect both you and your baby, reducing the risk of severe illness.

Treating the Flu Safely During Pregnancy

Managing flu symptoms safely is crucial during pregnancy:

• Safe medications: Paracetamol is recommended to reduce fever and relieve aches.

• Symptom relief: Rest, stay hydrated, and use steam inhalation for congestion. Honey can soothe a sore throat.

• Medications to avoid: Do not take ibuprofen, aspirin, and certain cold or flu combinations unless prescribed.

• Consult first: Always check with your GP before taking over-the-counter or natural remedies, ensuring both your safety and your baby’s.

The anti-influenza medication oseltamivir is recommended for use during the second and third trimesters of pregnancy to reduce the severity of flu. Oseltamivir use in the first trimester of pregnancy may be considered however safety data is limited. 

Is the Flu Vaccine Safe During Pregnancy?

Yes, the flu vaccine is safe at any stage of pregnancy. Vaccination not only protects the pregnant person from severe flu complications but also provides antibodies that help protect the baby in the first few months after birth. Australian health authorities strongly recommend the flu shot for all pregnant people. It is a key step in reducing risks associated with influenza.
