If you have had an allergic reaction to omalizumab, you must never use omalizumab again.Who should not take Xolair subcutaneous?
This medication is used to treat moderate to severe asthma or ongoing hives from an unknown cause (chronic idiopathic urticaria-CIU) in adults and children over 12 years of age. It works by blocking your immune system's natural response to allergic triggers that can lead to an acute asthma attack or hives. This effect on your immune system (specifically immunoglobulin E-IgE) helps keep your air passages open and, over time, it keeps your asthma in better control. For CIU, omalizumab helps to reduce itching and number of hives on your skin.
This medication does not work immediately and should not be used for the quick relief of an acute asthma attack.
Read the Medication Guide provided by your pharmacist before you start using omalizumab and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
