Wyndly vs Curex

Wyndly or Curex? How the two at-home allergy services differ

Both test at home, see you online and send treatment to your door. They differ on tablets, food allergy, the guarantee, price structure and published research. Curex publishes this page, so every Wyndly figure links to Wyndly’s own site, with the date we read it.

Short answer

Wyndly and Curex are both US telehealth services for allergy immunotherapy at home: an at-home blood test, an online clinician, and daily treatment under the tongue. Wyndly treats environmental allergies only and can prescribe FDA-approved allergy tablets as well as compounded drops; it publishes $99 a month billed annually and a 90-day money-back guarantee. Curex is the largest telemedicine platform for allergy immunotherapy at home, treats environmental and food allergies in every state with personalized drops, and has a 2,897-patient published study of its patients (retrospective and Curex-authored). Both approaches are effective and generally safe; they fit different patients. Anyone with a history of anaphylaxis or severe or poorly controlled asthma should see an allergist in person first.

Fair comparison

Where Wyndly is ahead

Curex publishes this page, so here is what Wyndly does that Curex does not, from Wyndly’s own published pages.

Wyndly
A tablet option alongside drops
Wyndly can prescribe FDA-approved sublingual tablets as well as compounded drops. For someone whose symptoms come from grass, ragweed or dust mite alone, a standardized, FDA-approved product is a real advantage. Curex prescribes drops only.

Wyndly
A published 90-day money-back guarantee
Wyndly publishes a 90-day money-back guarantee on treatment cost, with conditions (completing the plan and every check-in). Curex does not publish one.
Source: Wyndly FAQ
Wyndly
Clear ages and reuse of an existing test
Wyndly states that children from age 5 can be treated, and that its physicians will review an existing allergy test instead of a new one.

Fit

Which one fits you

Both approaches are effective and generally safe; they fit different patients. Neither is a substitute for an in-person allergist when you need one.

Wyndly may fit you better if…

One allergen drives your symptoms.Grass, ragweed or dust mite, where an FDA-approved tablet is an option.
You want a money-back guarantee in writing.Read the conditions on Wyndly’s FAQ before you sign up.
Your allergies are environmental only.Wyndly does not treat food allergies.

Curex may fit you better if…

You also have a food allergy.Curex treats environmental and food allergies at home.
You are allergic to several things at once.Pets, molds, trees and weeds, combined in one personalized formula.
Published outcomes matter to you.Read the 2,897-patient study, and its limits, before deciding.
You want insurance to cover testing and visits.Details at getcurex.com/pricing.

Evidence

What the research says about both

Both services deliver sublingual immunotherapy, the under-the-tongue form of allergy immunotherapy — the only treatment that retrains the immune system rather than masking symptoms. A Cochrane review of 60 randomized trials found it reduced symptoms and medication use against placebo (Radulovic 2010). The FDA-approved tablets were each tested in large placebo-controlled trials. For personalized drops, the 2017 AAAAI/ACAAI practice parameter declined to endorse customized aqueous drops on the evidence then available (PMID 28284533), which applies to drops from any provider.

Curex’s own study followed 2,897 adults and reported clinically meaningful improvement in 28% at 12 months and 45% at 24 months, adherence above 90%, and mostly mild side effects with no anaphylaxis reported (Tharpe 2026). It was retrospective, had no comparison group, counted only patients with at least a year of follow-up, and was written by Curex clinicians. Read it as real-world evidence, not as proof that one service works better than another.

Regulation

Tablets, drops and the FDA

The four allergy tablets (Grastek, Oralair, Ragwitek, Odactra) are FDA-approved products. Personalized allergy drops — from Wyndly, Curex or anyone else — are compounded and prescribed off-label, made from FDA-approved allergenic extracts, the same as in allergy shots; off-label does not mean unsafe or experimental.

Regulatory record

Personalized allergy drops, for environmental or food allergy, are made from FDA-approved allergenic extracts and prescribed off-label — a long-standing, legitimate practice that applies to every drops provider, not only Curex. Only a few single-allergen sublingual tablets are FDA-approved.

Has the FDA written to Curex about allergy drops? Once, in 2021: an untitled letter about how the drops were marketed. Curex changed its website, responded in April 2021, and has had no FDA correspondence about allergy drops since.

Does the 2025 FDA warning letter concern allergy drops? No. The September 2025 warning letter concerned marketing language for compounded GLP-1 weight-loss products; Curex made the requested changes.

Every letter and response: Curex and the FDA. The short version: Is Curex legit?

Safety

Before either service

Anyone with a history of anaphylaxis, severe or poorly controlled asthma, a suspected food or drug allergy, a young child, or someone who is pregnant should be evaluated by an allergist in person before starting any at-home immunotherapy. Both services screen for this, and both treat at home only people it is appropriate for. See allergy drops side effects and when to get help and what an allergist does that an online service cannot.
