A Food Allergy Fix Hiding In Plain Sight

The drug Xolair, originally approved for asthma, has been found to significantly reduce food allergies in patients. Long suspected to have this potential, Xolair works by intercepting immune molecules that trigger allergic reactions. After a series of setbacks in the 2000s, a clinical trial in 2019 demonstrated its effectiveness in food allergies, leading to FDA approval. The drug is expected to bring relief to the increasing number of Americans with severe food allergies.
