What is XOLAIR and what is it used for?
XOLAIR is an anti-IgE antibody.
It is an injectable prescription medicine used to treat:
- Moderate to severe asthma in people (6 years and older) whose asthma symptoms are not well controlled with the normal asthma medicines called inhaled corticosteroids. A skin or blood test will be performed to see if you have allergies to year-round allergens. It is unknown if XOLAIR is safe and effective in people with asthma under 6 years of age.
- Nasal polyps (Add-on maintenance treatment) in people 18 years of age and older when the normal medicines to treat nasal polyps called nasal corticosteroids have not worked well enough to control them. It is unknown if XOLAIR is safe and effective in people with nasal polyps under 18 years of age.
- Chronic spontaneous urticaria (CSU, also referred to as chronic idiopathic urticaria (CIU)), in people 12 years of age and older who continue to have hives and cannot be controlled with the normal H1 antihistamine treatment. It is unknown if XOLAIR is safe and effective in people with CSU under 12 years of age.
- Allergic bronchopulmonary Aspergillosis (ABPA), allergic rhinitis, and bullous Pemphigoid are also some diseases that omalizumab can treat, but is not FDA-approved.
