Expecting? On XOLAIR®? ENROLL in the EXPECT Pregnancy Registry. XOLAIR® (omalizumab) for subcutaneous use.
Before receiving XOLAIR, you should tell your doctor that you are pregnant. It is not known if XOLAIR may harm your unborn baby.


The purpose of the Expect Pregnancy Registry is to monitor pregnancy outcomes in women receiving XOLAIR (omalizumab) during pregnancy. Registries are observational, which means they are conducted to gather data. The information collected will provide doctors with a better understanding of the effect of XOLAIR exposure during pregnancy.

The EXPECT Pregnancy Registry seeks participants who:

  • Are Pregnant
  • Have received at least one dose of XOLAIR within 8 weeks prior to conception or at any time during pregnancy
  • You do not have to be taking XOLAIR now to be eligible.

    If eligible, you will be asked to participate in a telephone interview each trimester, postpartum, and every 6 months until your baby is 1 year old. No study site visits are required to participate. After your baby is born, if you continue to take XOLAIR while breastfeeding, you will be asked to participate in one more telephone interview when your baby is 18 months old. Talk to your healthcare provider if you are breastfeeding or plan to breastfeed. It is not known if XOLAIR passes into your breast milk. Talk with your healthcare provider about the best way to feed your baby while you receive XOLAIR. Eligible participants will be compensated for each telephone interview.

    What is XOLAIR?

    XOLAIR® (omalizumab) for subcutaneous use is an injectable prescription medicine used to treat adults and children 12 years of age and older with moderate to severe persistent asthma whose asthma symptoms are not controlled by asthma medicines called inhaled corticosteroids. A skin or blood test is performed to see if you have allergies to year-round allergens.
