What is XOLAIR (Omalizumab) Allergic Asthma Treatment?

XOLAIR for Allergic Asthma

  • XOLAIR is the only FDA-approved biologic drug to treat moderate to severe allergic asthma patients 6 years of age and older
  • XOLAIR significantly reduced asthma attacks.
  • XOLAIR is specifically designed to target IgE, an underlying cause of allergic asthma. XOLAIR captures the IgE in the body that may cause symptoms that can lead to an attack.
  • For appropriate patients, XOLAIR may provide flexibility on where it can be injected. It can be taken at your doctor's office or self-injected as determined by your doctor at home or outside of the healthcare setting.
  • XOLAIR is not inhaled, not a steroid, not something you take daily.
  • XOLAIR has been prescribed for over 17 years in allergic asthma patients 12 years of age and older.
  • XOLAIR has been prescribed for over 305,000* patients with allergic asthma.

What is the most important information I should know about XOLAIR?

Severe allergic reaction. A severe allergic reaction called anaphylaxis can happen when you receive XOLAIR. The reaction can occur after the first dose, or after many doses. It may also occur right after a XOLAIR injection or days later. Anaphylaxis is a life-threatening condition and can lead to death. Go to the nearest emergency room right away if you have any of these symptoms of an allergic reaction:

  • wheezing, shortness of breath, cough, chest tightness, or trouble breathing
  • low blood pressure, dizziness, fainting, rapid or weak heartbeat, anxiety, or feeling of “impending doom”
  • flushing, itching, hives, or feeling warm
  • swelling of the throat or tongue, throat tightness, hoarse voice, or trouble swallowing

Your healthcare provider will monitor you closely for symptoms of an allergic reaction while you are receiving XOLAIR and for a period of time after treatment is initiated. Your healthcare provider should talk to you about getting medical treatment if you have symptoms of an allergic reaction.

Additional XOLAIR Information

XOLAIR is a prescription medicine used to treat appropriate allergic asthma patients. XOLAIR is not a medicine you inhale, and it is not a corticosteroid. It is for injection, given under the skin every 2 or 4 weeks. If you or a child you care for has been diagnosed with allergic asthma, your asthma specialist may prescribe XOLAIR. To be prescribed XOLAIR, you must:

  • Have moderate to severe persistent allergic asthma
  • Be an adult or child who is 6 years of age or older
  • Have asthma symptoms that are not controlled—even though you are still taking inhaled corticosteroids. (Inhaled corticosteroids is a prescription medicine, breathed in through an inhaler, for people with asthma; it is intended for long-term, daily use to help prevent symptoms such as swelling in the lungs.)

If you think you may have allergic asthma, an asthma specialist can help with diagnosing and treatment options. Asthma specialists include either an allergist (specializes in diseases of the immune system, including allergic diseases and asthma) or a pulmonologist (specializes in diseases of the lungs and breathing, including asthma).
