For severe food allergies, Roche’s Xolair has been approved by the FDA and is used in the US.

Xolair, a drug therapy for food allergies, has been approved by the FDA as the first and only medication of its kind to be made available in the US. The FDA has given approval for the use of an IgE inhibitor to reduce allergic reactions, including life-threatening anaphylaxis, in adult and paediatric patients aged one year and older with one or more IgE-mediated food allergies. Over a follow-up period ranging from sixteen to twenty weeks, 68.8% of patients treated with Xolair every two to four weeks were able to tolerate at least 600 mg of peanut protein without inducing an allergic reaction.

The FDA has identified factors such as pollution, alterations in diet, and decreased exposure to microbes during the formative years of children as possible contributors to the rise in food allergies in the US over the past twenty years. In 2014, Xolair was granted approval for the treatment of refractory chronic spontaneous urticaria, leading to sales that surpassed one billion dollars. The patents for the formulations are scheduled to expire in November 2025 in the US and in November 2025 in Europe.

Genentech’s Xolair is intended to lessen the severity of allergic reactions brought on by accidental exposure to particular foods. It is the first medication that can protect individuals against allergens present in multiple levels. The medication should be taken on a consistent basis at regular intervals to lessen the likelihood of experiencing adverse reactions.

Over the next sixteen years, approximately one in sixteen adults in the US will be diagnosed with a food allergy. A study conducted by the National Institute of Allergy and Infectious Diseases found that 68% of people who took Xolair for four to five months could consume approximately two and a half peanuts without experiencing any symptoms.
