Xolair injection is only FDA approved for treating allergic asthma, nasal polyps, and chronic urticaria, and is currently not approved to treat allergies. However, there is good evidence to show that it may be helpful for allergic rhinitis or in addition to some immunotherapy desensitizing treatments and fair or weak evidence for some other allergic conditions. In Japan, Xolair is also approved to treat severe Japanese cedar pollinosis (JC) a form of seasonal allergic rhinitis that affects 38.8% of the Japanese population.
