Xolair is injected under the skin. A healthcare provider will give you this injection. Xolair is usually given every 2 or 4 weeks.
Before you start treatment with Xolair, your doctor may perform an allergy skin test or blood test to make sure this medicine is right for you.
You will be watched closely for a short time after receiving Xolair, 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 Xolair, 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.
