Normal changes in the immune system that occur during pregnancy may increase your risk of flu complications. You also have a higher risk of pregnancy complications, such as preterm labor and preterm birth, if you get the flu. You are more likely to be hospitalized if you get the flu while you are pregnant than when you are not pregnant. Your risk of dying from the flu is increased as well.
The Centers for Disease Control and Prevention (CDC) recommend that everyone 6 months of age and older—including pregnant women and women who are breastfeeding—get the flu vaccine each year. If you are pregnant, it is best to get the vaccine early in the flu season (October through May), as soon as the vaccine is available. You can get the shot at any time during your pregnancy. If you are not vaccinated early in the flu season, you still can get the vaccine later in the flu season. If you have a medical condition that further increases the risk of flu complications, such as asthma or heart disease, you should think about getting the vaccine before the flu season starts.
If you think you have the flu and you are pregnant (or you have had a baby within the past 2 weeks), contact your obstetrician or other health care professional right away. Taking an antiviral medication as soon as possible is recommended. Flu symptoms may include the following:
- Fever or feeling feverish
- Body aches
- Cough or sore throat
- Runny or stuffy nose
Antiviral medication is available by prescription. It is most effective when taken within 48 hours of the onset of flu symptoms, but there still is some benefit to taking it up to 4–5 days after symptoms start. An antiviral drug does not cure the flu, but it can shorten how long it lasts and how severe it is. Even if you just think you have the flu, it is best to be on the safe side and contact your obstetrician or other member of your health care team.
