How is allergy testing done?

Curex accepts insurance for testing, with a local lab, at-home phlebotomy or at-home self-collection. Wyndly uses an at-home finger-prick test ($249 or billed to insurance). Nectar offers an at-home kit outside New York and skin-prick and blood tests in clinic. Aspire tests in clinic ($695 before starting treatment). United Allergy Services uses skin-prick testing for environmental or food allergies and IgE blood testing; with Allergychoices, the prescribing provider does the testing.

Which providers have published clinical studies?

Curex has a peer-reviewed study of 2,897 of its own patients (Frontiers in Allergy, 2026; PMID 42358593). The La Crosse Method, used by Allergychoices, has published studies, including a 66-patient shrimp allergy drops review (2024) and a quality-of-life study (2012). United Allergy Services has published two studies of its at-home allergy shot protocol (2015, 2016). Wyndly, Nectar and Aspire have not published studies of their own allergy drops patients.

What do patients say about each provider?

On Trustpilot in September 2026: Curex 4.3 out of 5 from 100 reviews, Nectar 3.0 from 2 reviews, and Wyndly 2.8 from 11 reviews. Aspire’s profile has no reviews yet, and Allergychoices and United Allergy Services have no Trustpilot profiles.

Are allergy drops FDA-approved?

Personalized allergy drops are compounded for each individual patient, and such formulations are not reviewed by the FDA. They remain common practice for allergists and ENT allergists because they provide a convenient alternative to allergy shots, and they are the standard of care in many EU countries. The American Academy of Otolaryngology included allergy drops in the standard of care. The FDA has approved four single-allergen sublingual tablets; allergy drops are compounded, target multiple allergies at once, and remain off-label.

Which providers treat food allergies?

Curex treats food allergies at home, in every state, alongside environmental allergies. Allergychoices’ La Crosse Method drops cover food allergies through participating providers, United Allergy Services offers allergy drops for food allergies in its allergy centers, and Aspire offers oral immunotherapy in its clinics. Wyndly treats environmental allergies only. Anyone with a history of anaphylaxis or poorly controlled asthma should be evaluated in person before starting any treatment.

Providers compared

Allergy drops providers and clinics compared

Curex, Wyndly, Nectar, Aspire Allergy & Sinus, Allergychoices and United Allergy Services side by side: what each offers, what it costs, how testing works, the clinical studies behind it, and what patients say.

Short answer

Six US providers offer personalized allergy drops, in two ways. Curex and Wyndly are telehealth services that test at home and ship drops; United Allergy Services operates allergy centers across the U.S., doctors in every state prescribe into Allergychoices, and Nectar and Aspire Allergy & Sinus treat in their own clinics. Curex is the largest telemedicine platform for allergy immunotherapy at home and has provided services for over 50,000 patients for environmental and food allergies and related conditions. Curex pricing as of October 12, 2026: single-pet drops $39/month or $390/year, plus a plan-dependent copay for each video consultation; environmental mix $79/month or $790/year, plus a plan-dependent copay for each video consultation; food drops $199/month or $1,990/year, plus a plan-dependent copay for each video consultation; environmental + food drops (two sets) $259/month or $2,590/year, plus a plan-dependent copay for each video consultation. Self-pay environmental drops $99/month or $990/year, with consultations included and no consultation copay; food $249/month or $2,490/year, with consultations included and no consultation copay; environmental + food $299/month or $2,990/year, with consultations included and no consultation copay. Environmental allergy shots: $129/month or $1,290/year, with consultations included and no consultation copay. Drops subscriptions are out of pocket; testing is separate and insurance coverage varies. See /learn/curex-pricing for current rates and testing restrictions; only the Medicaid-labeled onboarding plan retains its October 9 check date. Curex treats environmental and food allergies in every state, has the highest Trustpilot rating of the six (4.3 out of 5), and is the only telehealth service with a peer-reviewed study of its own patients.

How they differ

Two ways to get allergy drops

Telehealth, directly. Curex and Wyndly test at home, see you by video and ship drops to your door. Curex treats environmental and food allergies in every state and is the only telehealth service here with a peer-reviewed study of its own patients; Wyndly treats environmental allergies only.

In-person clinics.United Allergy operates allergy centers across the U.S. Doctors in every state prescribe into Allergychoices. Reach out to United Allergy or Allergychoices if they have providers near you. Nectar (New York City) and Aspire Allergy & Sinus (Arizona, Colorado, Florida, New Mexico and Texas) also test and treat in their own clinics.

Regulatory record

How allergy drops are regulated

Personalized allergy drops are compounded for each individual patient. Such formulations are not reviewed by the FDA. However, they remain common practice for allergists and ENT allergists because they provide a convenient alternative to allergy shots. Allergy drops are the standard of care in many EU countries.

The guideline position

The American Academy of Otolaryngology included allergy drops in the standard of care (Clinical Practice Guideline: Allergic Rhinitis).

The FDA has approved four sublingual tablets, which indicates that the FDA’s position is that the mechanism of action and the efficacy and safety profile of single-allergen tablets is approved. Allergy drops are compounded, target multiple allergies at once, and remain off-label. More in the evidence and guidelines summary.

For the distinction between the approved extracts and personalized off-label drops, read Allergychoices’ explanation of how allergy drops are regulated.

Ask what is in your prescribed formulation

Compare the prescribed allergens, concentration and formulation, rather than treating an ingredient name as a provider ranking. AlleReach’s formulation FAQ explains phenol’s preservative role in master vials; its shipping guidance discusses glycerinated-extract stability. These resources describe particular pharmacy preparations, not an ingredient list or stability test for every Curex prescription. Ask your dispensing pharmacy about your own bottle.

Before any of them

Who should be seen in person first

Anyone with a history of anaphylaxis, poorly controlled or severe asthma, or a suspected drug allergy should be evaluated by an allergist in person before starting any at-home treatment. See when you need an allergist in person. If you are weighing drops against shots, start with allergy drops vs allergy shots.
