Oak Mix Allergy Shots (SCIT)
Oak-mix allergy shots (SCIT) are the most-prescribed Fagales formulation east of the Rockies — targeting the dominant spring tree allergen across the Southeast and Mid-Atlantic by total pollen volume, with daily counts exceeding 1,000 grains per cubic meter for weeks. No oak-specific SCIT RCT exists, but the Itulazax TT-04 trial (634 adults) documented meaningful oak-season symptom reduction in birch-sensitized patients, establishing birch-oak PR-10 cross-protection as clinically confirmed.
Oak Mix Allergy Immunotherapy: How It Works
Allergy immunotherapy is the only long-term treatment that re-trains the immune system to stop overreacting to oak mix — rather than just masking symptoms with antihistamines or steroids. By gradually exposing the body to controlled doses of oak mix allergen, immunotherapy shifts the underlying allergic response and produces relief that often outlasts treatment by 7–10 years.
There are two evidence-based forms of oak mix immunotherapy used today, both built on the same desensitization principle but delivered very differently.
of sustained relief after a complete immunotherapy course — the only allergy treatment with proven long-term effect after stopping.
Allergy Shots (SCIT)
Weekly injections of oak mix extract in a clinic, escalating over 3–6 months until a maintenance dose is reached. Continued monthly for 3–5 years. Longest clinical track record for oak mix allergy.
- Strongest evidence base for severe and polysensitized patients
- Covered by most insurance plans
- Requires 50–100+ in-person clinic visits across the full course
Allergy Drops / Tablets (SLIT)
Daily drops or dissolvable tablets containing oak mix extract, held under the tongue at home. Same desensitization principle, delivered without injections. WHO-recognized as an effective form of allergy immunotherapy since 2001.
- Taken at home — no weekly clinic trips, no needles
- Lower systemic reaction rate than allergy shots
- Curex offers prescription oak mix immunotherapy drops with allergist oversight

What is Oak Mix?
The biology, taxonomy, and clinical fingerprint of Oak Mix — the foundation of how SCIT targets it.
Oak catkins shed enormous quantities of pollen across the Southeast each spring — daily counts regularly exceed 1,000 grains per cubic meter for weeks in Atlanta, Charlotte, and Washington DC, making oak the dominant spring tree allergen by aggregate pollen mass in much of the US.

How Oak Mix Allergy Presents
Symptoms by body system — useful for distinguishing Oak Mix sensitivity from overlapping allergies and infections.
Respiratory
- Moderate-to-severe sneezing and profuse rhinorrhea during the March–May oak season across the Southeast
- Nasal congestion on high-pollen days — counts exceeding 1,000 grains/m³ for weeks in Atlanta, Charlotte, and Washington DC
- Itchy, swollen nasal passages that worsen on warm, dry, windy days when catkins peak
- Allergic asthma exacerbations — wheezing and chest tightness in oak-sensitized asthmatic patients
- Post-nasal drip and chronic cough from prolonged high-pollen exposure during the 6–8 week oak season
Ocular
- Intense bilateral eye itching and watering — common on high oak-pollen days in the SE
- Conjunctival redness and swelling (allergic conjunctivitis) during peak weeks
- Morning crusting and periorbital puffiness after overnight pollen accumulation
- Reduced outdoor tolerance during the core March–April oak-pollen peak
Dermal
- Oral allergy syndrome (OAS) to raw apple, hazelnut kernel, peach, cherry, or carrot via Que a 1 / Bet v 1 PR-10 cross-reactivity — less prominent than with birch monosensitization, but possible in oak-sensitized patients with high PR-10 IgE
- Contact urticaria from direct pollen contact in highly sensitized individuals
- Atopic dermatitis flares coinciding with high oak-pollen weeks in spring
Systemic
- Severe fatigue from prolonged high-pollen exposure — the SE oak season is 6–10 weeks of sustained exposure
- Sleep disruption from nighttime nasal obstruction during peak March–April weeks
- Impaired outdoor work and recreation during prime spring weather
- Cumulative quality-of-life impact from one of the longest sustained pollen exposures of any US tree allergen
In the Southeast, oak puts more pollen into the air than any other spring tree by total mass — daily counts over 1,000 grains per cubic meter for weeks. We don't have an oak-specific RCT, but the Itulazax TT-04 trial showed birch SCIT measurably reduces oak-season symptoms, which gives us strong immunologic rationale for treating oak-sensitized patients with a birch-anchored Fagales mix.

Patients sensitized to one allergen often react to others sharing similar proteins. This map shows the documented molecular overlaps.
Oak's Que a 1 shares 72–95% sequence identity with birch Bet v 1, and ImmunoCAP inhibition assays show white oak pollen extract inhibits 77.4–81.5% of Bet v 1 IgE binding (Jeong 2016). This makes oak one of the strongest cross-reactive pairs in the Fagales PR-10 family — and explains why birch SCIT reduces oak-season symptoms in the Itulazax TT-04 trial.

Cor a 1.04 PR-10 OAS; less prominent in oak-monosensitization than birch
Oak PR-10 Oral Allergy Syndrome (less prominent than birch)
Oak monosensitization can produce PR-10 OAS to raw apple, hazelnut kernel, peach, cherry, carrot, and celery — but OAS is considerably less common and less severe in oak-monosensitized patients than in birch-sensitized patients. If your OAS is prominent, consider whether birch co-sensitization (Bet v 1) may be the primary driver. See the white birch page for the complete PR-10 OAS food table. A board-certified allergist can separate oak-vs-birch sensitization via component-resolved testing.
Is SCIT Right for Your Oak Mix Allergy?
Answer five questions to assess whether oak-mix SCIT is likely right for your spring tree allergy.
How severe are your spring oak-season symptoms (March–May)?
The Oak Mix SCIT Protocol
Oak-mix SCIT uses non-standardized Q. alba and Q. rubra extracts (often blended into Eastern X-tree mixes) in a conventional build-up and maintenance ladder. High-pollen-volume Southeast patients benefit from initiating build-up out of season — summer is ideal — to avoid co-exposure during titration.
Injections begin at 1:10,000 w/v and increase incrementally based on local reactions. Southeast patients with high ambient oak pollen exposure during the March–May season should ideally complete build-up before this window. A summer start (June–August) is preferred. Mandatory 30-minute post-injection observation period at every visit.
Monthly maintenance injections sustain oak-specific and Fagales PR-10 cross-reactive tolerance. Most patients see symptom improvement by the second oak season. The Itulazax TT-04 trial confirms that Bet v 1/Que a 1 cross-reactive immunotherapy produces meaningful oak-season symptom reduction even without a dedicated oak extract.
Lasting benefit of 7–12+ years is associated with completing the full 3–5 year course. Because oak seasons are long and high-intensity in the Southeast, patients who discontinue early frequently relapse quickly.
Extract Concentration Ladder
You progress through each vial during build-up. Concentration increases ~10x per step.
What the Research Shows for Oak Mix SCIT
No SCIT RCT has been conducted specifically for Q. alba or Q. rubra. All efficacy estimates derive from the birch-homologous family evidence base, particularly the Itulazax TT-04 oak-season secondary endpoint — the strongest available clinical evidence for oak SCIT.
- Oak-season symptom reduction (birch-homologous cross-protection)62%Itulazax TT-04 secondary endpoint — oak season; ALK/EMA 2019, N=634 birch-sensitized adults
- Bet v 1 IgE inhibition by white oak pollen extract79%Jeong et al., J Korean Med Sci 2016 (ImmunoCAP inhibition — 77.4–81.5% range)
- Sensitization rate in US allergy clinic populations30%Pooled US allergy clinic data — 20–40% range routinely reported
No oak-specific SCIT RCT exists for US populations. The Itulazax TT-04 oak-season secondary endpoint and the Jeong 2016 inhibition assay provide the strongest mechanistic and clinical rationale for oak SCIT within a birch-anchored Fagales approach. Clinicians should be transparent with patients that the SCIT evidence for oak derives from birch-homologous family extrapolation rather than a dedicated oak RCT.

Oak Mix SCIT Side Effects
Oak-mix SCIT side effects follow the standard inhalant SCIT profile. Southeast patients initiating build-up during the March–May oak season face higher reactivity risk from active co-exposure — a summer build-up start is strongly preferred.
Local reactions
4 documentedSystemic reactions
4 documentedA 30-minute post-injection observation accompanies every oak SCIT dose, whether given in a clinic or self-administered at home with Curex — where the first dose and any dose change are supervised live over Zoom and a prescribed epinephrine auto-injector is confirmed on hand. Southeast patients should initiate build-up in summer (June–August) to avoid the elevated reactivity risk that occurs when build-up doses coincide with peak ambient oak pollen counts in March–April.
SCIT vs Alternatives for Oak Mix
Oak-sensitized patients have four main pathways: Fagales-anchored SCIT (treating oak via birch-homologous cross-protection) — now self-administered as a weekly at-home shot with Curex — sublingual drops, avoidance strategies (limited given oak's extreme pollen output), and daily seasonal medications.
| Criterion | SCITBest | SLIT | Avoidance | Medications |
|---|---|---|---|---|
| Effectiveness | High — family-level Phase 3 evidence via Itulazax TT-04 oak-season secondary endpoint | Moderate — no FDA-approved oak SLIT tablet in US; off-label drops available | Low — oak pollen counts >1,000 grains/m³ for weeks; essentially unavoidable in SE | Moderate — antihistamines + nasal steroids for mild-to-moderate symptoms |
| 5-yr cost | $3,500–$15,000 over 5 years | Varies by provider; sublingual drops are a general allergy modality, not Curex's product | Low — HEPA, pollen masks, air purifiers | $500–$2,000 over 5 years |
| Duration | 3–5 year course | 3–5 year course | Indefinite — no tolerance change | Indefinite — seasonal use |
| Convenience | At-home weekly self-injection with Curex; summer start preferred for SE patients; first dose and dose changes supervised live over Zoom | Daily at-home — no clinic required | High inconvenience in spring outdoor season | High convenience |
| Safety | Excellent — your oak serum is USP <797> sterile-compounded, the prescribing physician supervises every dose change over Zoom, a prescribed epinephrine auto-injector is on hand, and a 30-minute self-observation follows | Favorable — no systemic anaphylaxis in EU SLIT trials | Safe | Generally safe |
| Lasting effect | 7–12+ years after completion | Emerging — less durability data vs SCIT | None — symptoms return each March | None — must take every season |

SCIT is the only therapy that can provide lasting tolerance to the highest-volume spring tree pollen in the US — reducing oak-season symptoms not just this year but potentially for 7–12 years after completing the 3–5 year course. With Curex, eligible patients self-administer that shot at home for $129/month instead of committing to weekly clinic injections, with the first dose and every dose change supervised live over Zoom and a prescribed epinephrine auto-injector confirmed on hand.
What Oak Mix SCIT Actually Costs
Oak-mix SCIT is covered by most major US insurers under standard allergy immunotherapy benefits when ordered by a board-certified allergist with supporting positive skin test or specific IgE. Oak is typically included in a multi-tree Eastern mix — pre-authorization should specify the full tree mix composition and leading allergens. Curex at-home IgE testing identifies specific oak mix sensitization before allergist consultations, eliminating the need for an initial skin-test visit.

Oak Mix SCIT — Frequently Asked
Quick answers to the questions patients ask most before starting treatment.
Oak trees are wind-pollinated and rely entirely on aerial pollen dispersal for fertilization — meaning they must produce enormous quantities of pollen to ensure reproduction. Unlike insect-pollinated trees that produce sticky, targeted pollen, wind-pollinated oaks release light, dry pollen in volumes that can reach 1,000 to 5,000 grains per cubic meter of air for weeks across the Southeast during peak season. A single mature oak can release billions of pollen grains per season. This massive volume — not any particular difference in protein allergenicity — is why oak drives more allergy symptoms per day than almost any other spring tree in the US, even though individual oak proteins may be less potent sensitizers than birch Bet v 1 on a per-grain basis.
