Latitude's map, and everyone outside it

Per the clinic's own site, checked September 2026 — Northern California: Redwood City, San Francisco, San Rafael (Marin), and San Ramon. Southern California: Pasadena, Irvine, San Diego, Sherman Oaks, and West Los Angeles. New York metro: Manhattan (Upper East Side), Brooklyn, Long Island, and White Plains (Westchester). That is 13 listed locations across three metros. Openings and closings happen, so check Latitude's locations page for the current list before you plan around it.

Close enough to sustain supervised up-dosing visits at the frequent cadence OIT up-dosing requires for 6–12 months — that is the active phase of oral immunotherapy, and Latitude reports an average of about 8.4 months to maintenance. In a 2022 study of 67 patients offered commercial peanut OIT, 52% declined it, and the single most-cited reason (28.5%) was time burden, defined as travel distance, number of up-dosing visits, and lifelong treatment. A useful test: could you make this drive on a school night, twice a month, through a winter? If the honest answer is no, distance is not a detail — it is the decision.

Virtual visits exist for some consultations — one public review references a virtual appointment (and, in that reviewer's account, an antihistamine-stop instruction that came without advance warning). But OIT up-dosing is inherently in-person: dose escalations happen under observation precisely because that is when reaction risk peaks. No responsible OIT program is remote at its core. That is why the at-home route uses a different modality entirely — sublingual drops, where typically only the first dose is taken in an office — rather than attempting remote OIT.

They are built on opposite assumptions. Latitude's 13 clinics assume you live nearby and can come in frequently through the active phase; its footprint spans three metros, and the public record shows no waitlist complaint cluster. Food Allergy Institute runs a destination model from Long Beach: the clinic says more than 50% of its patients travel from outside California, families describe flying in every 8–12 weeks from Florida, Texas, New York, and even the UK and Australia, and its first clinic outside Southern California was scheduled to open in New Jersey on September 15, 2026. If you live in a Latitude metro, Latitude's geography is simply easier; see [how the programs' published figures compare](/learn/food-allergy-clinics-compared).

Primarily a pediatric-focused practice, but adults have been accepted. One 36-year-old peanut-allergic patient publicly described being taken on "although they stated they don't normally treat adults," citing a peanut component IgE threshold of 2.0 or greater and a 6–12 month path to maintenance. If you are an adult, expect a case-by-case answer rather than a standing program. Whether any program fits is a clinical question — anaphylaxis history or severe, poorly controlled asthma routes to in-person assessment regardless of which provider you are considering.

Latitude does not publish its one-time OIT program fee. Patients report it: more than $4,000 in the Bay Area (one Reddit poster: "I have to shell out > $4000 for so-called program fee which they say is definitely not covered by insurance") and over $5,000 in New York per an Atly reviewer — so treat it as a $4,000–$5,000+ range by region and time. Diagnostics and visits are "typically covered" in-network per Latitude's FAQ, with payment plans and FSA/HSA eligibility for the fee. As a category, the leading in-person food allergy clinics can cost $10,000+ per year of treatment. Confirm current figures directly — with them and with us.

Four real routes. First, the fully at-home sublingual route: Curex, the only fully at-home food allergy program, treats in every state — testing through local labs or self-collection kits, doctors by video or text, drops shipped by a licensed compounding pharmacy — on gentler doses that more patients finish, (Curex food-plan rates, client commercial terms as of 2026-10-12: Food Allergy Drops: $199/month or $1,990/year. Unlimited number of foods, as clinically prescribed; plus insurance copay for each video consultation. Environmental + Food Allergy Drops: $259/month or $2,590/year. Two treatment sets, with unlimited number of allergens as clinically prescribed; plus insurance copay for each video consultation. Food Drops Self-Pay Plan: $249/month or $2,490/year. Food allergy drops; consultations included without a consultation copay. Environmental + Food Drops Self-Pay Plan: $299/month or $2,990/year. Environmental and food allergy drops; consultations included without a consultation copay. For the listed allergy plans, the annual subscription costs the equivalent of 10 monthly payments instead of 12: two months of subscription fees saved, or 16.7% compared with paying monthly for a year. This is subscription savings, not a discount on testing, copays or your total medical bill. Other products have their own payment terms; GLP-1 annual rates are shown separately. Treatment fees are self-pay. Insurance benefits are verified during onboarding. Each video consultation has a plan-dependent specialist copay, normally $35, which can be lower or higher depending on your plan. Deductibles and coinsurance may also affect your responsibility. The subscription covers compounded allergy drops and non-insured clinic services, including shipping, asynchronous consultations and care management. Insurance-category subscriptions add a copay for each video consultation. The environmental, food and combined self-pay drops plans and the environmental allergy shots plan include consultations without a consultation copay. Certain self-collection tests are not insurance-covered and are priced separately. Allergy IgE, celiac and Alpha-Gal tests may be covered by insurance, depending on your plan. IgG food sensitivity testing is not covered by insurance; the laboratory bills the patient directly. Verify coverage and the laboratory estimate before ordering. See /learn/curex-pricing and confirm eligibility, testing costs and a personalized written quote). Second, ask allergists within your radius whether they run standard OIT on published protocols — a national directory lists OIT clinics in 35 states, which also means 15 states plus DC have none listed, and the directory is self-registered and incomplete, so call directly. Third, for a history of anaphylaxis or uncontrolled asthma that needs a physician in the room, Allergy Associates of La Crosse in Onalaska, Wisconsin treats exactly those patients on sublingual drops, with one in-person first visit and rechecks that can be virtual. Fourth, discuss Xolair with a local allergist: FDA-approved since February 2024 for ages 1+, it reduces reaction severity on accidental exposure but does not desensitize, and avoidance continues. [The access page](/learn/no-oit-clinic-near-me) maps them in detail, state by state.

Not identically, and the honest numbers cut both ways. In the one head-to-head peanut trial in children (PMID 25528358), OIT raised reaction thresholds about 141-fold at 12 months versus about 22-fold for sublingual immunotherapy — but OIT also produced significantly more adverse reactions and more withdrawals. Over a longer course, in NIH-funded studies at UNC, 67–70% of children on extended peanut SLIT could tolerate 750–800 mg or more of peanut protein, a quarter to a third passed a full 5,000 mg challenge, and toddlers started at ages 1–4 reached a median 4,443 mg after three years against 143 mg on placebo — with no dose in any of the three studies requiring epinephrine (PMIDs 31493887, 36828080, 37815782). Latitude publishes internal outcome figures (94% of all ages desensitized, 98% under age 4, per its site in 2026). Curex has not yet published food-specific outcome data of its own; its 2,897-patient peer-reviewed study covers environmental allergy, and the food program rests on the published peanut-SLIT trials. What the at-home route offers is a gentler protocol patients finish, and food challenges still happen in a clinic on every protocol, including for Curex patients.
