Anti-IgE is a treatment that stops an allergic reaction before it begins, helping prevent asthma attacks by blocking the antibody that causes the reaction.  The treatment is approved for patients age 12 and older who have moderate-to-severe allergic asthma.

 

      Anti-IgE is different from immunotherapy but it is also given by injection.  Anti-IgE should only be administered by staff that has training and experience in handling a reaction you could have after receiving an injection of Anti-IgE.
