Is Curex a scam or legit?

Curex is a legitimate, licensed telehealth allergy company — not a scam. It holds LegitScript certification, an independent third-party verification that confirms compliance with applicable pharmacy and healthcare laws. With 50,000+ patients treated and a 4.5-star Google rating on 546 reviews, it has the largest verified patient feedback base of any telehealth SLIT provider in the US. Its allergy drops are compounded by Allergychoices, the company behind the La Crosse Method Protocol — the most widely used sublingual immunotherapy protocol in the US, with 2,000+ participating providers and 275,000+ patients treated over more than 50 years. Allergychoices holds Validation Institute certification (2018) and has contracts with the US Navy and Mayo Clinic. The treatment itself — sublingual immunotherapy — is supported by a 2010 Cochrane review (Radulovic et al. 2010) of 60 RCTs showing symptom reduction with SMD of -0.49 (Radulovic et al., PMID: 21154351). That said, legitimate does not mean perfect. Every publicly available concern deserves examination.

Curex maintains a single consolidated Google Business Profile (95 5th Ave, Floor 4, New York, NY 10003) with a 4.5-star rating on 546 reviews as of April 2026. This is by far the largest Google review base among telehealth SLIT providers — Wyndly, Quello, and HeyAllergy do not maintain Google Business Profiles with patient reviews. Nectar has a physical NYC clinic with a separate GBP.

The Google review profile reveals consistent themes. Positive reviews cite effective symptom reduction for pollen, dust mite, cat, and dog allergies within 3-12 months; convenience of home-delivered drops versus weekly office visits for shots; and responsive clinical team (Dr. Chet Tharpe and staff mentioned by name). Negative reviews consistently cite billing surprises (promotional prices followed by higher charges), difficulty canceling annual subscriptions, and confusion about insurance coverage for drops versus consultations. The gap between Google (4.5 stars) and independent platforms (Trustpilot 3.3, BBB C) is notable — this pattern is common in subscription telehealth where satisfied patients leave Google reviews and dissatisfied patients file BBB complaints. Quello's Trustpilot profile (4.9/5, 86 reviews) consists entirely of invited reviews — a metric that should be interpreted cautiously.

Curex has received two FDA letters — neither concerned the safety of allergy drops or patient harm. Understanding what each letter actually addressed is critical.

The March 2021 CBER untitled letter addressed how Curex marketed allergenic extracts — specifically promotional language, not the safety or legality of the drops themselves. The September 2025 CDER warning letter concerned compounded GLP-1 medications (semaglutide and tirzepatide) for weight loss — a completely separate product line from allergy treatment. Neither letter alleged patient harm from Curex's allergy treatment program. For context, Wyndly, Nectar, Quello, and HeyAllergy all have zero FDA letters on record as of April 2026.

Curex holds a C rating from the Better Business Bureau with 54 complaints on file. The company is not BBB-accredited. Complaint themes are consistent across BBB, Trustpilot, and Google one-star reviews: unexpected charges after promotional sign-up prices, auto-renewal of annual subscriptions without clear cancellation options, and confusion about which services are covered by insurance versus self-pay. These are billing and subscription management complaints — not clinical safety concerns. BBB ratings for subscription telehealth companies are driven by this complaint pattern. Curex actively responds to both Google and BBB reviews, though responses follow a templated format.

Curex's allergy drops are compounded by Allergychoices, Inc. (Onalaska, WI), the company behind the La Crosse Method Protocol — the most widely used sublingual immunotherapy protocol in the United States. The protocol originates from Allergy Associates of La Crosse, founded by Dr. David L. Morris in 1970. Allergychoices has treated 275,000+ patients through a network of 2,000+ participating providers nationwide. The company received Validation Institute certification in 2018 and holds contracts with the US Navy and Mayo Clinic. No other SLIT compounding pharmacy in the US operates at comparable scale — competing companies like All-American Allergy Alternatives and Acclaim Allergy Solutions have significantly smaller footprints. This pharmacy partnership is a verifiable credential: patients can confirm that their drops are compounded under the La Crosse Method Protocol, which has over 50 years of clinical use.

To put Curex in proper context, here is how it compares to other telehealth SLIT providers on key trust-relevant metrics as of April 2026.

Wyndly's 90-day guarantee requires documented daily compliance, symptom tracking, and completed check-ins to qualify. Curex addresses financial risk differently through insurance billing: at $39/month, the 90-day financial exposure is approximately $117. Wyndly also offers both custom drops and FDA-approved SLIT tablets — the only telehealth provider doing so. Nectar offers in-person services at its NYC clinics that complement virtual care — an advantage for NYC-based patients who need skin prick testing. HeyAllergy has the strongest third-party medical review presence among competitors (Zocdoc: 4.37/5 on 195 reviews via affiliated AllergyDox providers). Curex's fully virtual model trades in-person testing for nationwide accessibility in all 50 states, using lab-based IgE ImmunoCAP testing at any LabCorp or Quest location. Curex is the only telehealth SLIT provider that publicly discloses its patient volume (50,000+), its pharmacy partner and protocol (Allergychoices / La Crosse Method), and maintains a Google Business Profile with verified patient reviews.

Save your money and look elsewhere if any of these apply. If a formal money-back guarantee is important to you, Wyndly's 90-day program (requiring documented daily compliance, symptom tracking, and check-ins) provides that structure. Curex addresses financial risk differently through insurance billing — at $39/month, your 90-day exposure is approximately $117. If your allergies are limited to one of the five FDA-approved tablet allergens (grass, ragweed, dust mite), an FDA-approved tablet through your pharmacy benefit — potentially as low as $15-25/month with a manufacturer copay card — may be cheaper and backed by more rigorous individual product data. If you prefer in-person care with skin prick testing, Nectar (NYC) or a traditional allergist is a better fit. If billing transparency is your top concern, read the consistent complaint themes in BBB and Trustpilot reviews before signing up — and ask Curex directly about cancellation terms, auto-renewal, and total annual cost. If your allergies are mild and a $15/month generic cetirizine handles your symptoms — skip immunotherapy entirely. The economic case for any SLIT provider does not hold when OTC medications adequately control your quality of life.
