How to use the Xolair injection for asthma

Xolair is administered through an injection. This drug lasts a long time – injections are usually needed once every 2 to 4 weeks. It takes several weeks to months before the effect of Xolair is noticeable – the frequency and severity of shortness of breath attacks gradually decrease.

Store Xolair in the fridge (not freezer).
