Omalizumab (Xolair) is an injectable biologic medication used to treat several chronic allergic conditions [1.2.1]. The answer to 'What is the onset time for omalizumab?' varies, with some patients seeing improvement in a few weeks and others needing up to 4 months [1.2.2, 1.3.2].

According to the manufacturer's official guidelines, the total combined time out of refrigeration for Xolair should not exceed 48 hours (2 days). This strict timeframe is crucial for maintaining the medication's effectiveness, making it vital for patients to understand how long can Xolair be left unrefrigerated and under what conditions.
