While the drug, Xolair, offers a new layer of protection to people who may have life-threatening reactions to common foods, and especially to those who are allergic to several foods, its use comes with important caveats.
Does Xolair cure food allergies?
Xolair is not a cure for food allergies, nor can it be used to treat acute reactions.
People who take Xolair must continue to avoid foods that they are allergic to.
But Xolair can significantly reduce the odds that people with severe food allergies will develop acute reactions if they ingest minute amounts of allergens, like peanuts or eggs in prepared foods, or are exposed to trace amounts in some other way.
