New Research Suggests Food Allergy Treatments May Be Becoming More Personalized

Families managing multiple food allergies may soon have more treatment options thanks to new research led by Stanford Medicine.

A randomized clinical trial published in JAMA Pediatrics found that children with peanut allergy and at least two additional food allergies benefited from individualized treatment approaches using omalizumab, an FDA-approved medication, either alone or in combination with oral immunotherapy. Researchers concluded that different treatment strategies may be appropriate depending on each patient's needs and family circumstances.

The study followed 117 children over one year. Researchers found that both treatment approaches increased participants' ability to tolerate foods that had previously caused allergic reactions, although the combination therapy required a greater time commitment and had higher dropout rates due to side effects and treatment burden.

Why This Matters

Food allergies affect approximately 8% of children in the United States, and about 40% of those children are allergic to more than one food. Managing multiple allergies often requires strict avoidance, careful label reading, and constant vigilance when eating away from home.

Experts say these findings could allow allergists to better personalize treatment plans instead of relying on a single approach for every patient. Omalizumab may help reduce the risk of severe reactions from accidental exposure, while some patients may also benefit from oral immunotherapy under medical supervision.

Looking Ahead

Researchers emphasize that these therapies are not cures, and patients should continue avoiding known allergens and carrying prescribed emergency medication. However, the expanding range of treatment options represents meaningful progress for families living with food allergies.
