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.
Omalizumab is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of omalizumab on the baby.

How should I use omalizumab (Xolair)?
Before you start treatment with omalizumab, your doctor may perform an allergy skin test or blood test to make sure this medicine is right for you.
Omalizumab is injected under the skin. A healthcare provider will give you this injection. Omalizumab is usually given every 2 or 4 weeks.
You will be watched closely for a short time after receiving omalizumab, to make sure you do not have an allergic reaction to the medication.
Your condition may be treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.
If you also use a steroid medicine, do not stop using it suddenly or you may have unpleasant withdrawal symptoms. Talk with your doctor if any of your asthma medications do not seem to work as well in treating or preventing attacks.
While using omalizumab, you may need frequent medical tests, such as allergy tests and lung function tests. Your stools may also need to be checked for parasites, especially if you travel.
Your condition may not improve right away. For best results, keep receiving the medication as directed. Talk with your doctor if your symptoms do not improve after a few weeks of treatment.
