Today was a big day with the Williams family — first time trying eggs.

Mom shared that bloodwork showed a mild egg sensitization, so the big question was:
Is this a true clinical allergy… or something we can safely introduce?

That’s exactly why supervised food challenges matter.

One spoonful turned into several pretty quickly. That’s always a good sign. Even the French toast got approval.

Labs give us data.
But real-world exposure under supervision gives us answers.

The goal isn’t just “passing.”
The goal is confidence. Inclusion. Less fear at birthday parties and family breakfasts.

If your child has been labeled allergic based on numbers alone, it may be time for a conversation.

You don’t know what’s possible until you explore it safely.

🥜 Let’s Talk About the Stanford Peanut Patch Study.

Why am I pushing back?

From what’s being proposed, infants with peanut allergy may be randomized to either a placebo or the peanut patch to see if it works.

Here’s my issue:

In 2026, the standard of care for infants with peanut allergy is evolving toward early oral immunotherapy and structured food introduction — not placebo. We already have strong real-world experience showing that carefully dosed peanut protein by mouth can work very well in this age group.

So if you’re going to study a patch, compare it to oral immunotherapy in infants. That’s a meaningful question.

But placebo vs. patch? That feels outdated.

And here’s my bigger concern:

If the patch gets approved, there will likely be a massive marketing push. Multi-million-dollar campaigns. Key opinion leaders. Messaging that this is “the solution.”

We’ve seen that play out before with Palforzia — strong branding around something that, at its core, was still peanut protein therapy.

Money doesn’t mean something is bad.
But money absolutely shapes the narrative.

Do I think there may be a very small subset of toddlers who might benefit from a patch? Possibly.

Do I see most of my infant peanut patients needing it if approved? No.

In my practice, we can usually accomplish protection through carefully structured oral introduction — without a device, without a patch, and without the added cost layer.

My job isn’t to hype or to tear down.
It’s to talk to you like family and help you think critically.

If you’re considering enrolling in a patch study or just confused about your options, I’m happy to walk through the pros, cons, and what I’d realistically recommend.

Marketing is loud.
Data matters more.

🥛 Severe Milk Allergy + EoE History — Can We Still Do OIT?

I get this question all the time:
“Can we even consider OIT with numbers that high?”
“What about EoE?”

So here’s a real teaching case I reviewed during Sunday charting.

5-year-old.
History of Eosinophilic esophagitis (on medication).
Severe milk allergy.

Pre-OIT milk IgE= 89.
That’s very elevated.

Instead of defaulting to avoidance, we carefully microdosed and slowly built tolerance through structured milk OIT.

Today?
He’s tolerating 65 mL of milk daily — nearly a cup in baked form — without issue.

Next step: introducing visible milk this weekend.

And yes — we’re monitoring closely for EoE symptoms. When you treat high-volume, complicated milk cases, you learn how to watch patterns, adjust dosing, and down-dose if needed.

Most allergists are not comfortable treating:
• High IgE milk (like 89)
• Milk + EoE history
• Complex desensitization cases

That’s okay.

We see a large volume of complicated milk and egg patients — among the highest in the Southeast — so these scenarios are routine for us.

This wasn’t a “perfect case.”
This was a real child.
High numbers.
Complicating history.
Thoughtful plan.
Measured progress.

Options exist — even when things look severe on paper.

If you’ve been told milk is off the table forever, it may be worth a conversation.

We’re happy to review cases and let you know what’s realistic.

“Why weren’t we taught oral immunotherapy in fellowship?”

In fellowship, many of us were taught that OIT was research-only. Dangerous. Not standard. Don’t touch it.

But here’s what happened in real life.

Patients were grateful. Outcomes were improving. Data started supporting it. And slowly, practice patterns began to change.

The problem isn’t that doctors are wrong. It’s that culture in medicine changes slowly.

Some programs now teach OIT. Some still don’t. Some allergists have experience. Some don’t.

But here’s the key: even if you don’t offer OIT, you should at least discuss it and refer appropriately.

Avoidance alone is no longer the only option.

Medicine evolves — and our responsibility is to evolve with it.

🥛🥚 The Volume Tells the Story.

I genuinely didn’t realize just how many severe milk and egg allergy families we were serving… until we started tracking.

Since November — in just three months — 80 new patients with severe milk and egg allergies.

Families are traveling 6–7 hours.
We have patients coming from Florida.
Even referrals connected to Vanderbilt University.

Why?

Because many allergists and even academic centers aren’t offering milk and egg OIT. Not because they’re wrong — but because they’re not comfortable with it.

And comfort comes from volume.

We see a high volume of milk and egg cases. That experience has allowed us to become very precise with microdosing — carefully introducing tiny, controlled amounts and building up safely.

That’s how you get results.

We’re also comfortable with:
• Microdosing protocols
• Slow build strategies
• Down-dosing when needed (though we rarely have to)

When you treat enough patients, you develop pattern recognition and confidence that only repetition can build.

If milk or egg allergy has been limiting your child’s life — and you’ve been told avoidance is the only option — we’re happy to offer a second opinion.

Milk.
Egg.
Or any type of oral immunotherapy.

We’re here.

🌰 High Numbers. Real Protection. Practical Goals.

I want to share this case so families understand what options actually exist.

This is a 10-year-old I saw in March with very elevated labs:
• Pistachio: 48
• Walnut: 36
• Cashew: 32
• Peanut: Positive

Those are high numbers. The kind that make most people feel stuck.

But here’s the key — this family didn’t care about freely eating nuts.
They just wanted protection from accidental exposures.

That’s an important distinction.

So we built a slow, structured oral immunotherapy plan — peanut and tree nut coverage — gradually increasing tolerance in a controlled way.

Eventually, we transitioned him to daily maintenance using MightyMe Puffs — the same multi-nut puffs often used for early introduction in babies.

He now takes four puffs daily (about 10–20 mg of mixed nut protein).

Goal achieved:
✔️ Protection against accidental exposure
✔️ Reduced anxiety
✔️ Freedom to live life without constant fear

Not every family wants “food freedom.”
Some just want safety.

And even with high IgE numbers, protective desensitization is very possible.

If you’ve been told the numbers are “too high” to do anything — that’s not always true. There are different approaches depending on your goals.

If this sounds like your situation, we’re happy to talk through options or point you toward someone experienced in this space.

Sometimes the win isn’t eating the nut.
It’s not being afraid of it.

🥜 Palforzia Is Off the Market. Now What?

You may have seen the news about Palforzia.

I’ve shared this before, but I’ll say it again: the marketing behind Palforzia was brilliant. Millions of dollars were poured into positioning it as something unique and revolutionary.

At its core?
It’s pharmaceutical-grade peanut flour.

That’s not a knock — oral immunotherapy works. Peanut protein works. But the messaging often made it seem fundamentally different from what allergists have already been safely using in structured OIT programs for years.

So its discontinuation doesn’t change much for us or our patients.

If anything, it highlights how much money can shape perception in medicine. When you remove the branding and the packaging, the concept remains the same: controlled, measured peanut exposure under medical supervision.

For families who were prescribed Palforzia:
• This does NOT mean OIT is gone.
• This does NOT mean your progress stops.
• There are alternative ways to continue therapy.

An allergist experienced in OIT can guide you using other peanut formulations — often at significantly lower cost.

If you were impacted or have questions about next steps, I’m always happy to talk through options and help you think clearly about what makes sense for your child.

Knowledge is greater than marketing.

The OUTMATCH data turned some heads 👀

Multi-allergen oral immunotherapy showed similar effectiveness to Xolair in helping patients build tolerance to foods.

One option: $30–40K+ per year with ongoing injections.
The other: carefully dosed exposure to the actual food.

Different mechanisms.
Comparable outcomes.

Cutting-edge research continues to show that natural food exposure, done correctly, can be very effective.

“Do we use the EpiPen right now?”

Dr Chacko here 💙 — and this is one of the most common questions I get, even from close friends.

A family texted me about their daughter on OIT who had hives and some vomiting. The big question: Is it time for epinephrine?

Here’s how I explain it.

Epinephrine is the treatment of choice. It’s safe. And you will never be wrong for using it when it’s clearly needed.

But sometimes we assess the full picture.

If your child has hives but is stable, interactive, calm — watching Ms. Rachel on their phone, distracted and acting like themselves — you may have a little time. In those situations, giving Zyrtec and closely monitoring with epinephrine in hand can be reasonable.

Now if they’re repeatedly vomiting, pale, lethargic, struggling, or not acting right — that’s different. That’s when epinephrine is the right move.

So when I say, “Ask Ms. Rachel,” I mean this:
Are they comfortable enough to sit and watch their show? If yes, you may have a moment. If not — don’t wait.

When in doubt, epinephrine is always the safe choice. But sometimes you have a little time to assess carefully.

Hope that helps bring clarity and confidence to families navigating OIT. 💙

Florida ➡️ Dr Chacko’s office 💙🐊

Addison is in her first year at the University of Florida and dairy has been super hard to avoid. With milk IgE close to 100 (and casein around 75), she was told the usual: “Just avoid. No need to retest.”

But mom found Dr Chacko on Instagram 🙌🏽 and knew there had to be another option.

At Dr Chacko’s office, we’re very intentional about the numbers — especially milk levels greater than 100. We’ve helped 30–40 patients just like Addison over the past decade. While many allergists may not feel comfortable treating at those levels, experience and data matter.

Now? We’re slowly and safely introducing dairy back into her diet — step by step. The goal? A future video where Addison is enjoying milk, ice cream, and pizza parties on the regular. 🍦🍕

Thank you for trusting Dr Chacko with your journey. If you’ve been told to “just avoid” and you’re wondering if there’s another path, reach out. We’re happy to help — or connect you with someone who can.

When Dr. Chacko asked Dr. Gideon Lack what advice he’d give his own son and daughter-in-law about preventing food allergies… the answer was refreshingly simple. 😊

Breastfeed if possible.
Start solids early with fruits and vegetables.
Introduce peanut early — peanut butter or puffs.

And the best part?
“Of course, this is the advice I’d give my own family… whether they listen is another story.” 😄

Even the world’s leading allergy researcher knows: parenting advice is easier to give than to follow. But the science is clear — early introduction matters, especially when there’s a family history of food allergies.

Real science. Real life. Real conversations that help families make confident decisions.
