Flu during pregnancy: When to Seek Advice About Symptoms

If you think you have flu during pregnancy, contact a doctor or your maternity team promptly. Pregnancy increases the chance of serious flu complications, so the usual approach of waiting several days to see whether an illness settles is not appropriate. You do not need to prove that it is flu before asking for advice.

Describe the illness and when it started

Flu often arrives quickly with marked tiredness, body aches, cough and fever, although not everyone has a fever. Other respiratory infections can look similar. Tell the clinician when you first felt unwell, whether you can drink and whether your breathing has changed.

Mention how many weeks pregnant you are, any asthma or other medical conditions and medicines already taken. If you have a test result, share it, but do not delay the call while trying to arrange a test. A short symptom timeline helps the clinician decide what assessment and treatment are needed.

Ask about treatment early

Antiviral medicines treat influenza rather than simply easing discomfort. Clinical guidance recommends prompt treatment for suspected or confirmed flu in pregnancy, with oseltamivir commonly preferred. A clinician should choose and prescribe the treatment for you.

The greatest benefit is usually from starting within the first 48 hours, but treatment can still be useful later, especially with severe illness. Contact the team even if you think you have missed that window. A negative rapid flu test does not reliably exclude infection. A clinician may start treatment before laboratory confirmation because waiting can delay useful care.

Check symptom remedies separately

Rest and regular fluids can help while you follow the care plan. Before taking a fever or cold remedy, have its ingredients checked for pregnancy suitability. Paracetamol may already be included in a combination product, making it easy to take the same medicine twice.

The cold remedies guide explains these checks. Do not start leftover antibiotics for flu; antibiotics do not treat the influenza virus. A clinician may prescribe them for a separate bacterial complication when indicated.

Know when the situation is urgent

Call emergency services for sudden chest pain, coughing up blood or severe breathing difficulty, such as gasping or being unable to speak. Do not drive yourself. Worsening illness, trouble drinking or feeling unable to manage at home also needs prompt medical advice.

Contact maternity care immediately if your baby’s usual movements reduce or change. Do not assume that being ill explains a movement change.

After recovery, ask about pregnancy vaccinations and your seasonal flu protection. Vaccination helps prevent illness; it does not replace assessment or treatment for symptoms that have already started.
