How do I take omalizumab (Xolair)?

Since omalizumab (Xolair) is administered by injection at the clinic or doctor's office, you will just need to keep your appointments.
Omalizumab is used to treat moderate-to-severe persistent allergic asthma, the type of asthma that occurs when you react to allergens like dander, pollen or dust mite particles. Your doctor will test you to be sure that your asthma is triggered by allergy before giving you this medicine. Omalizumab is always given as a subcutaneous injection (just under the skin). The dose will depend on how sick you are to start, how you respond to the medicine and your body weight. You can receive injections once every two or four weeks. Because this drug can produce a life-threatening reaction called anaphylaxis, you must be monitored closely, two hours for the first three visits, and for at least 30 minutes during your visits thereafter.

Read the medication guide carefully beforehand so you know the problems to look out for when you leave the office, and ask questions if you don't understand what you need to do.
