Are you worried about food allergies? Let's talk about Xolair!

Are you or your child allergic to nuts, peanuts, milk, or eggs? If so, you probably know the fear and anxiety you feel when you go to a party, event, or have to eat something at the store. How difficult is it to live with the fear of what will happen if you unknowingly ingest even a small amount of a food you are allergic to? So, today we are going to talk about a recently approved new drug that brings some hope to the millions of people who suffer from such severe food allergies .

What exactly is Xolair?

Simply put, Xolair is not a brand-new drug. It's actually a well-tested drug that has been used for more than 20 years for other conditions. It's specifically used to treat asthma in children over 6 years old, some chronic allergies, and people with nasal polyps.

The best part is that there is long-term data on the safety of this drug. For example, it has now been confirmed that it is safe even during pregnancy and is not associated with a risk of cancer as initially suspected.

However, like all medications, there can be minor side effects. Pain and fever at the injection site are common. However, medical experts say, "We wouldn't think twice about using this for the right patient, at the right time."

The US Food and Drug Administration (FDA) recently approved this drug to reduce the risk of severe, even life-threatening allergic reactions (anaphylaxis) that can occur after inadvertently ingesting a food due to a food allergy .

Does this medicine really work? What does the research say?

A large study was recently conducted to find the answer to this question. It involved 180 people aged 1 to 55 years with allergies to tree nuts such as peanuts, milk, eggs, wheat, and cashews.

This is what was done in this research.

1. One group was given the Xolair vaccine for 16-20 weeks.

2. The other group was given a placebo.

3. Then, both of them were fed a very small amount of protein, about half the size of a peanut , to see if they would develop severe allergic symptoms (whole-body rash, coughing, vomiting).

4. After that, they tested things like cashews, milk, and eggs by gradually increasing the dosage .

The results are truly amazing.

From people who took XolairBetween 80% and 85% of people were clearly protected from severe reactions that could occur if they unknowingly ate a small amount of an allergenic food.

Not only that, but about half of those who took the drug were able to tolerate the equivalent of 25 peanuts at a time . This is a really big deal, because the amount you unknowingly ingest is much less than you would normally.

So is this a 'magic pill'? Is everything okay?

This is where we need to understand. While Xolair is a great hope, it is not a 'magic bullet' that will completely cure allergies.

Let's take a look at the advantages of this and what we need to be careful about in the table below.

Cost and other challenges

One of the biggest challenges with this drug is its high cost . Based on American prices, it costs hundreds of thousands of Sri Lankan rupees per month. Therefore, it is questionable to what extent this will be accessible to the general public in Sri Lanka.

We also need to understand the psychological stress of living with food allergies . Imagine, if a child is allergic to milk, they are afraid to go to a restaurant where they eat out, even for a family member's birthday. Because even a small mistake in the kitchen can endanger the child's life. Recently, there was a news report of a doctor who, despite informing the restaurant that she had an allergy and taking all the necessary precautions, died due to the allergen in the food. This shows how serious this situation is.

A drug like Xolair could provide great safety and freedom to families living in such fear.
