What Peanut OIT Actually Is (And What It’s NOT) – Oral Immunotherapy Explained
Your baby has just been diagnosed with a peanut allergy.
You’re terrified.
Your mind jumps straight to worst-case scenarios.
You’re Googling at 2am.
You’re reading every food label three times.
You’re wondering how on earth you’re going to keep your child safe for the rest of their life.
Then someone mentions oral immunotherapy, OIT.
Suddenly, there’s hope.
A treatment that could help your child tolerate peanut?
A way to reduce the fear around accidental exposure?
Something proactive you can do?
Before you cling to that hope too tightly, I need to be really honest with you.
Because OIT is often talked about in a way that’s incomplete, and families are making huge decisions based on information that doesn’t tell the whole story.
So let’s slow this down and talk about what OIT actually is, and what it isn’t.

What Oral Immunotherapy Actually Is
Oral immunotherapy (OIT) is a medical treatment where your child is given very small, carefully measured amounts of peanut protein, which are gradually increased over time.
This happens under strict medical supervision.
The goal is not to cure the allergy.
The goal is to increase your child’s tolerance threshold, so that small, accidental exposures are less likely to cause a severe, life-threatening reaction.
I often explain it like this:
OIT aims to move families from
“a crumb could be dangerous” to “accidental exposure is less terrifying.”
That difference matters. A lot.
In Australia, OIT is available through specialised hospital programs, including early-intervention pathways such as ADAPT for babies under 12 months, offered in select hospitals. Research shows that earlier intervention often leads to better outcomes, because infant immune systems are more adaptable and still “learning” what to react to and what to tolerate.
What OIT Involves (The Part Families Aren’t Always Prepared For)
OIT isn’t a single appointment.
And it’s definitely not a quick fix.
Most programs involve:
Regular hospital visits for dose increases
Daily dosing at home (no skipping, even when sick, travelling, or exhausted)
Months to years of treatment
Close medical monitoring
Managing reactions that can occur during the process
This is structured, medical treatment, not something you try on your own at home.
What OIT Can Do
For some families, OIT can be genuinely life-changing.
It can:
Reduce the risk of severe reactions from accidental exposure
Increase your child’s tolerance threshold
Provide peace of mind that tiny amounts aren’t immediately life-threatening
Allow more flexibility in daily life
Show particularly strong results when started early (under 12 months)
For the right family, with the right support, those benefits can feel enormous.
What OIT Is Not (This Is the Part I Need You to Hear)
OIT is not a cure.
It does not:
Eliminate the peanut allergy
Mean your child can freely eat peanut butter sandwiches
Guarantee permanent tolerance
Remove the need for ongoing caution
OIT is not:
❌ A cure for peanut allergy
❌ Something you can do without medical supervision
❌ A guarantee your child will tolerate peanut forever
❌ Quick or easy
❌ Risk-free
❌ Right for every child or every family
The goal isn’t “my child can eat anything.”
The goal is “my child is safer if they’re accidentally exposed.”
That distinction is critical, and often misunderstood.
What OIT Really Looks Like Day to Day
This is where families are often caught off guard.
OIT means committing to:
Daily dosing. Every single day. Even when you’re sick, travelling, running late, or completely exhausted
Hospital appointments for dose increases and monitoring
Reaction management. Reactions can, and do, happen during treatment
Lifestyle coordination. Childcare, school, and family members all need to understand the protocol
Emotional resilience. There will be pauses, setbacks, and moments of doubt
Time. This is months to years, not weeks
It’s not a magic fix.
It’s a marathon, not a sprint.
For some families, the trade-off is absolutely worth it.
For others, it simply isn’t, and that is completely okay.
Why Early Intervention Matters
Research increasingly shows that earlier OIT often leads to better outcomes.
That’s why programs like ADAPT focus on babies under 12 months, their immune systems are more adaptable and still forming long-term patterns.
This doesn’t mean older children can’t benefit, many do.
But if your baby has just been diagnosed, knowing that early-intervention options exist is important.
The reality, though, is that:
Access is limited
Programs aren’t available everywhere
Not every child is a suitable candidate
Is OIT Right for Your Family?
Only you, alongside your medical team, can answer that.
OIT may be worth exploring if:
Your child has a confirmed peanut allergy
They are very young (especially under 12 months)
You have access to a specialised program
You can commit to daily dosing and regular appointments
You understand it’s a treatment, not a cure
OIT may not be right if:
Your child has poorly controlled asthma
Daily dosing consistency isn’t realistic
The nearest program is too far away
The emotional load would outweigh the benefits
There is no judgement either way.
This is a deeply personal decision.
Questions to Ask Your Allergist Before Starting OIT
If you’re considering OIT, these questions matter:
Am I eligible for programs like ADAPT in my area?
What are realistic success rates for my child’s age and allergy profile?
What does the time commitment truly look like?
What happens if we miss doses or need to travel?
What are the risks during treatment?
How do you define success with OIT?
What does long-term maintenance involve?
What happens if we stop treatment?
Clear answers help families make confident decisions.
Oral immunotherapy can be genuinely life-changing for some families.
The research is promising.
The outcomes can be incredible.
But OIT needs to be understood for what it really is:
a treatment that builds tolerance, not a cure that removes allergy.
It’s hard work.
It’s a long-term commitment.
It’s not right for everyone.
If you’re considering OIT, go in with:
Open eyes
Realistic expectations
Strong medical support
That’s how you make the best decision for your child and your family.
