How to Get Allergy Shots: The Complete 7-Step Onboarding Roadmap
Getting allergy shots involves seven steps: recognizing your symptoms warrant immunotherapy, obtaining a PCP referral, visiting an allergist for testing, receiving a diagnosis and treatment plan, getting insurance pre-authorization, waiting 2-4 weeks for custom extract preparation, and attending your first injection. Most patients wait 6-10 weeks from first phone call to first shot. The build-up phase then requires weekly injections for 3-6 months before transitioning to monthly maintenance doses.

Getting allergy shots takes roughly 6-10 weeks from your first call to your first injection, covering a PCP referral, allergist consultation, allergy testing, insurance authorization, and custom extract preparation — then weekly shots begin.
Why Getting Started with Allergy Shots Takes More Steps Than You Expect
Most patients who ask about allergy shots are surprised to learn how many steps are involved before the first injection. Unlike an antibiotic prescription you pick up at the pharmacy, allergy immunotherapy is a personalized, physician-supervised medical program. Each patient's extract is custom-formulated based on their specific IgE sensitization profile, which means testing comes before treatment — always.
The journey starts with allergy testing. Before visiting an allergist, completing at-home allergy testing can give you a head start — Curex offers comprehensive IgE testing covering 40+ allergens, with results reviewed by a licensed allergist, so you arrive at your specialist appointment already informed about your trigger profile.
Once you're in the system, the main time sink is usually not the allergist's schedule — it's insurance pre-authorization. Most plans require step therapy documentation (you've tried medications first) and prior authorization for immunotherapy CPT codes (95165 for extract preparation, 95115/95117 for injection administration). Building in time for this paperwork prevents frustrating delays.
Patient selection also matters. SCIT is most appropriate for patients with allergic rhinitis, allergic asthma, or stinging insect hypersensitivity whose symptoms persist despite pharmacotherapy. Your allergist will assess whether you're a candidate based on symptom burden, confirmed allergen sensitization, and your ability to commit to 3-5 years of regular visits.
From first phone call to first injection, expect 6-10 weeks. Most of this wait is insurance authorization and custom extract preparation — not allergist availability.

The 7 Steps from Suspecting Allergies to Your First Injection
Each step in the allergy shot onboarding process has a realistic timeframe. Understanding the sequence helps you plan and prevents the frustration of unexpected delays. Here is what to expect at each checkpoint on the road to your first injection.
Recognize that your allergy symptoms are significantly affecting quality of life despite medications — this is the clinical threshold for immunotherapy consideration. Obtain a PCP referral (many insurance plans require this) and schedule your allergist consultation. At the consultation, the allergist reviews your history, performs a physical exam, and orders allergy testing — skin prick testing or specific IgE blood testing.
Based on your testing results, you receive a confirmed diagnosis and a personalized treatment plan: which allergens will be in your extract, the expected build-up schedule, and the projected timeline and cost. Simultaneously, your allergist's office submits insurance pre-authorization for immunotherapy — this step alone can take 1-3 weeks depending on your insurer's process.
Your custom allergen extract is mixed individually based on your sensitization results — US practices commonly blend up to 10 allergens per vial. Preparation takes 2-4 weeks at the allergist's compounding facility. Once your extract is ready and insurance authorization is confirmed, you attend your first injection visit: a small starting dose, 30-minute observation, and scheduling of your build-up phase appointments.
Same proven results. No clinic visits.
Curex's at-home allergy shots deliver the same allergen desensitization as clinic SCIT — for a flat $129/month, with no clinic visits and no facility fees.

How long does it take to get allergy shots after your first allergist visit?
Most patients wait 4-8 weeks after their first allergist appointment before receiving their first injection. This timeframe includes allergy test result review (usually same day for skin prick testing, 1-2 weeks for blood IgE tests), insurance pre-authorization for immunotherapy (1-3 weeks, the most variable step), and custom allergen extract preparation (2-4 weeks). Some practices with in-house extract preparation and efficient insurance workflows can complete the process in under 4 weeks. Others with complex insurance requirements or outsourced extract compounding may take 8-10 weeks. Calling your allergist's office proactively to follow up on the insurance authorization can meaningfully shorten wait times.
What documentation do I need to get insurance to cover allergy shots?
Most insurers require documentation of step therapy — evidence that you've tried and had inadequate response to first-line allergy treatments such as non-sedating antihistamines (loratadine, cetirizine) and intranasal corticosteroids (fluticasone, budesonide). Your PCP's records of prior allergy medication prescriptions are valuable here. You'll also need confirmed allergy testing results (skin prick test or specific IgE blood test) showing sensitization to specific allergens. Your allergist's office typically manages the pre-authorization submission using CPT codes 95165 (extract preparation) and 95115 or 95117 (injection administration). Some plans also require the allergist to be in-network and a PCP referral on file.
Can I start allergy shots without a referral?
Whether you need a referral depends on your insurance plan. PPO plans often allow direct specialist access without a referral, while HMO plans typically require a PCP referral before covering an allergist consultation and immunotherapy. Even with plans that don't require a formal referral, your PCP's documentation of your allergy history and failed medication trials is valuable for insurance pre-authorization of the shots themselves. If you're uninsured, you can schedule directly with an allergist and pay out of pocket — no referral is needed. The allergist's office can usually tell you quickly what your plan requires when you call to schedule.
What is the build-up phase of allergy shots?
The build-up phase is the first 3-6 months of allergy shot treatment, during which you receive injections once or twice a week at gradually increasing doses. Starting at a very small, dilute dose, each visit moves your dosage incrementally upward — your immune system is being trained slowly to tolerate increasing amounts of the allergen. This controlled escalation is what makes immunotherapy disease-modifying rather than just symptom-suppressing. By the end of the build-up phase, you reach the maintenance dose, which is the highest dose your immune system has been trained to tolerate. At that point, injection frequency decreases significantly to every 2-4 weeks during the maintenance phase.
Are there any contraindications to starting allergy shots?
Several conditions make starting SCIT inadvisable or require modification. Uncontrolled asthma (FEV1 below 70% predicted) is a significant contraindication — active wheezing or poorly controlled asthma substantially increases reaction risk. Beta-blocker use is a relative contraindication because these medications can blunt the epinephrine response needed to treat anaphylaxis. Severe cardiovascular disease, active autoimmune conditions, and significant immunodeficiency are also concerns. Pregnancy is a relative contraindication for initiating immunotherapy — women already on a stable maintenance dose may continue with allergist oversight, but SCIT should not be started during pregnancy. Your allergist will complete a full medical history review to assess all contraindications before prescribing.
How much do allergy shots cost without insurance?
Without insurance, allergy shots typically cost $1,000 to $4,000 per year, with year one (the build-up phase) at the higher end due to more frequent visits. Cost components include the initial allergy testing ($150-$400), custom extract preparation ($200-$600 per vial set), and injection administration visits ($20-$60 per visit for a typical 25-30 minute appointment including observation). During the build-up phase, weekly visits add up quickly. Some allergists offer self-pay discounts or payment plans. At maintenance frequency (monthly), annual costs drop to $500-$1,500 depending on the practice. Getting quotes from 2-3 allergists in your area for uninsured pricing is reasonable and common practice.
Can you get allergy shots for multiple allergens at once?
Yes — US allergy practice commonly combines multiple allergen extracts into a single vial or a small set of vials, so patients can be desensitized to multiple allergens simultaneously. A single vial may contain up to 8-10 allergens (pollens, dust mites, pet dander, mold spores). In contrast, European practice typically uses single-allergen preparations. Multi-allergen immunotherapy is effective and standard in the United States, according to AAAAI practice parameters. Your allergist will design the multi-allergen extract formula based on your specific sensitization results, grouping compatible allergens to minimize cross-reactivity and degradation issues within a vial.
When do allergy shots start working?
Most patients notice some symptom improvement within 3 to 6 months of starting the build-up phase, though the timeline varies by allergen and individual immune response. Dust mite and grass pollen patients often report earlier improvement, while mold and pet dander may take longer. Full benefit — including medication reduction and improved tolerance to allergen exposure — typically develops after 12 to 18 months of consistent treatment. Studies including the Durham et al. landmark trial in NEJM (1999) demonstrate that benefits can persist for several years after stopping treatment, particularly after 3-5 years of maintenance, which is why committing to the full course is important for long-term results.
