Asthma in Pregnancy (cont.)

Other Treatments

Flu shot: Also called the influenza vaccine, this shot can help prevent you getting the flu. The risk of severe asthma attack is very high if you get the flu. Because a severe asthma attack can deprive the fetus of oxygen, the shot is recommended in the second and third trimesters of pregnancy. (Its safety during the first trimester is more questionable.)

Allergy shots: If you took allergy shots before you became pregnant and had no severe reaction to the shots, you should continue the shots during pregnancy. However, you should not start allergy shots during pregnancy.

Pregnancy Outcome

Asthma attacks can have a number of negative effects on pregnancy outcome. Poor asthma control is linked to preterm birth, low birth weight, and stillbirths in the fetus and hypertension in pregnant women. Women who become pregnant while being treated for asthma should not stop using their medication unless they are specifically told to do so by their health-care provider.
