Where To Get An Allergy Shot: Clinics, Costs, and One-Time Myths
There is no single "an allergy shot" — subcutaneous immunotherapy (SCIT) is a 3-to-5-year multi-injection course (Durham 1999 NEJM). You start at a board-certified allergist's freestanding office — not a hospital outpatient department, which can bill $24,400 for what a freestanding clinic charges $1,827. 81.5% of US counties have zero allergists (Wu 2019).

You get allergy shots at a board-certified allergist's freestanding office — but clarify first: there is no single one-time allergy shot; SCIT requires a 3-to-5-year course of weekly then monthly injections.
The essentials
The singular phrasing — "where to get an allergy shot" rather than "allergy shots" — typically signals a first-visit or one-off framing: someone who has not yet committed to a full immunotherapy course and wants to know where to walk in. The first thing to clarify is that no single SCIT shot exists in the immunotherapy sense. Subcutaneous immunotherapy is intrinsically a 3-to-5-year multi-injection course. Durham SR et al. (NEJM 1999;341:468-475, DOI 10.1056/NEJM199908123410702) established that a 3-to-4-year grass SCIT course produces sustained clinical remission for at least 3 further years after stopping — durability that requires the full course, not a single injection.
The other "single allergy shot" use case is a depot corticosteroid (Kenalog/Depo-Medrol) — a one-time steroid injection that suppresses allergy symptoms for weeks but produces no disease-modifying effect. Cox L et al. (J Allergy Clin Immunol 2011;127[1 Suppl]:S1-S55, DOI 10.1016/j.jaci.2010.09.034) explicitly discourage this approach for routine allergic rhinitis because of systemic steroid risk and the absence of durable benefit.
Where to get SCIT: traditionally, at a board-certified allergist's freestanding office (American Board of Allergy and Immunology, ABAI), under direct or delegated-nurse supervision, with a 30-minute post-injection observation period (Cox 2011 PP3, Summary Statement 32). Per Wu I et al. (AAAAI 2019), 81.5% of US counties have zero practicing allergists — meaning for most rural patients, "where to get" involves driving 30–90+ minutes per visit. State Medicaid acceptance among allergists ranges from 13.4% (New York) to 72.3% (California) per Ho FO, Bilaver LA et al. (Am J Manag Care 2024;30[8]:374-379, DOI 10.37765/ajmc.2024.89588).
For patients who cannot easily reach an allergist, Curex's at-home SCIT program answers the question differently: a personalized serum sterile-compounded to USP <797> standards, board-certified allergist review and oversight, the first injection and every dose change supervised live over Zoom, a prescribed epinephrine auto-injector confirmed on hand, and self-administered weekly at home — $129/month all-inclusive. The consultation is conducted via telehealth, eliminating the geographic barrier that prevents many patients from ever starting.
Avoid hospital outpatient departments (HOPDs) for in-clinic SCIT unless you have verified costs in advance. The same CPT 95117 injection generating a $11.97 Medicare-allowed physician fee at a freestanding clinic generates a facility fee that can multiply the patient bill tenfold at an HOPD. Kaitlin Johnson at M Health Fairview MN (PBS NewsHour Weekend 2024) was billed $24,400 for a 40-allergen panel that surrounding freestanding clinics quoted at $800–$1,827.
The first step before any injection regimen is the consultation: an allergist reviews your history, performs or orders allergy testing (skin prick or serum-specific IgE), identifies which allergens are clinically relevant, and formulates a patient-specific extract. Tkacz JP et al. (Curr Med Res Opin 2021;37[6]:957-965, DOI 10.1080/03007995.2021.1903848) found 23.9% of immunotherapy patients never returned for their first injection visit — the consultation-to-shot drop is a documented friction point that at-home delivery directly addresses.

Is there such a thing as a one-time allergy shot?
No — in the subcutaneous immunotherapy (SCIT) sense, there is no one-time allergy shot. SCIT requires a build-up phase of approximately 24–28 weekly injections followed by a maintenance phase of monthly injections for 3–5 years total (Cox L et al., J Allergy Clin Immunol 2011;127[1 Suppl]:S1-S55). The durability evidence from Durham SR et al. (NEJM 1999;341:468-475) requires completing the full course to achieve the 3-year post-treatment remission demonstrated in the trial. A single depot corticosteroid injection (Kenalog, Depo-Medrol) is sometimes called a "one-time allergy shot" colloquially, but Cox 2011 PP3 discourages this for allergic rhinitis because it provides symptomatic relief only, with no immune modification, and carries systemic steroid risks.
How do I start the process of getting allergy shots?
Start by scheduling a consultation with a board-certified allergist (ABAI). You can search the AAAAI Find an Allergist directory at aaaai.org by zip code and insurance plan. At the consultation, the allergist takes a clinical history, performs or orders allergy testing (skin prick testing CPT 95004, or serum-specific IgE blood testing CPT 86003), identifies which allergens are IgE-sensitized, and determines whether you are a candidate for SCIT based on your diagnosis, symptom severity, and absence of contraindications. Once the extract is formulated and a dose schedule is established, build-up injections typically begin within 1–4 weeks. The whole consultation-to-first-injection process takes a few weeks to a month in most practices.
What is the difference between a steroid allergy shot and immunotherapy allergy shots?
A steroid "allergy shot" (depot corticosteroid — Kenalog / triamcinolone, Depo-Medrol / methylprednisolone) is a single intramuscular injection of corticosteroid that suppresses allergy symptoms for weeks by broadly dampening the immune response. It is not disease-modifying, produces no lasting immune tolerance, and carries systemic corticosteroid risks including blood-sugar elevation, bone-density loss with repeated use, and adrenal suppression. Cox L et al. (J Allergy Clin Immunol 2011;127[1 Suppl]:S1-S55) explicitly discourage parenteral steroids for routine allergic rhinitis. Subcutaneous immunotherapy (SCIT) allergy shots — the subject of this page — are a 3-to-5-year course of allergen-extract injections that retrain the immune system to tolerate allergens, producing durable remission (Durham 1999 NEJM) without systemic steroid exposure.
Does it cost more to get allergy shots at a hospital?
Yes — significantly more in most cases. Hospital outpatient departments (HOPDs) bill a facility fee on top of the physician fee for any procedure, including allergy shots. The PBS NewsHour Weekend 2024 investigation documented Kaitlin Johnson (M Health Fairview MN) receiving a $24,400 bill for a 40-allergen evaluation and initiation that surrounding freestanding allergist clinics quoted at $800–$1,827. The same CPT 95117 allergy injection has a 2025 Medicare-allowed physician amount of $11.97 at a freestanding clinic; at an HOPD, the facility fee component can add hundreds of dollars per visit on top of that. The clinical procedure is identical; only the billing classification differs. Always ask whether a clinical site is HOPD-classified before the first appointment.
Can I walk in to an allergist office for a first allergy shot?
No — you cannot walk in for an allergy shot without an established allergist relationship. Allergy shots require patient-specific extract formulation based on allergy testing results, a prescribing allergist who has reviewed your history and determined SCIT is appropriate, a written dose schedule, and documentation that contraindications (uncontrolled asthma, beta-blockers, pregnancy initiation) have been screened. This pre-shot workup takes at least one consultation visit and often an allergy-testing visit. Walk-in urgent care or emergency departments do not carry patient-specific allergen extracts. The process begins with a scheduled consultation, not a walk-in injection.
How far do most people travel to get allergy shots?
The median travel distance for allergy care varies substantially by geography. Per Wu I et al. (AAAAI 2019), 81.5% of US counties have zero practicing allergists, and only 0.3% of rural counties have an allergist versus 23.2% of urban counties — meaning most rural patients travel considerably for specialist care. Some travel 30 to 90+ minutes each way per injection visit during the build-up phase, when weekly visits are required. This travel burden is a documented contributor to the high dropout rate in immunotherapy: Tkacz JP et al. (Curr Med Res Opin 2021) found only 43.9% of patients in a large commercial database reached maintenance. Patients in underserved areas who cannot reach an allergist within a reasonable distance may consider Curex's at-home SCIT program ($129/mo) — the initial consultation is conducted via telehealth, a personalized serum is shipped to the home, and weekly self-administered shots eliminate the travel burden entirely while maintaining board-certified allergist oversight.
What should I bring to my first allergy shot appointment?
For your first allergy shot (first build-up injection after the consultation), bring your insurance card, a list of current medications (especially beta-blockers and ACE inhibitors, which are contraindications or cautions per Cox 2011 PP3), and a record of any relevant allergy history or prior reactions. Wear short sleeves or a loose top that easily exposes the upper outer arm. Plan for the mandatory 30-minute post-injection observation — bring a book or headphones. Do not exercise vigorously within 2 hours before the injection: exercise increases systemic allergen absorption and reaction risk. If you have asthma, your allergist may check peak flow before the injection. Bring your rescue inhaler. The nurse will screen for current symptoms and asthma control before administering each injection, per the standard pre-injection protocol.
