Asthma and pregnancy

If you have asthma, it's hard to predict whether your asthma symptoms will be any different in pregnancy. Some women's symptoms will improve, others may not see any change and some will find they get worse.


Most asthma medications are safe to take in pregnancy. These include preventer (inhaled steroid) and reliever inhalers, steroid tablets and montelukast. If your asthma is well controlled and you continue to take your asthma treatment regularly, there is little or no risk to your baby. It is important to discuss any changing asthma symptoms and medications with your GP, asthma nurse or hospital consultant as soon as possible.

There are things you can do to help manage your condition during pregnancy, such as:

  • Use your preventer inhaler (steroid inhaler) regularly and with good technique. There are some helpful videos that show you how to use your inhalers properly on the Asthma and Lung UK website.
  • If you smoke, try to cut down or stop and avoid exposure to second hand smoke. Your midwife can refer you to free support to help you stop smoking.
  • Avoid things that trigger your asthma symptoms – for example, pet fur.
  • Control hay fever with antihistamines – talk to your local pharmacist about which antihistamines are safe to take in pregnancy
  • Avoid hay fever triggers, such as mowing the lawn
  • Continue to exercise and eat a healthy diet
  • Make sure you have the flu vaccine offered during pregnancy
