What should I discuss with my healthcare provider before using omalizumab (Xolair)?
You should not use omalizumab if you are allergic to it.
Tell your doctor if you have any signs of infection (fever, swollen glands, general ill feeling), or if you have ever had:
- any other allergies (foods, pollens, etc);
- allergy shots;
- a severe allergic reaction (anaphylaxis);
- an infection caused by parasites (such as giardia, malaria, leishmaniasis, hookworm, pinworm, toxoplasmosis, and many others);

- a latex allergy.
Using this medicine may increase your risk of certain types of cancers of the breast, skin, prostate, or salivary gland. Talk to your doctor about your individual risk.
While you are using omalizumab, you may also have an increased risk of becoming infected with parasites (worms) if you live in or travel to areas where such infections are common. Talk with your doctor about what to look for and how to treat this condition.
Some babies born to mothers using omalizumab during pregnancy had low birth weight. However, it is not known whether this was due to omalizumab use or to severe asthma in the mothers. The benefit of treating asthma may outweigh any risks to the baby. Tell your doctor if you are pregnant.
If you are pregnant, your name may be listed on a pregnancy registry to track the effects of omalizumab on the baby.
It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.
